Kangxi 4 Character Mark: What It Reads, What It Means, and How to Tell a Genuine Mark

Short answer

• A Kangxi four-character mark is an inscription of four Chinese characters on the base of a piece of porcelain, naming the Kangxi reign of 1662 to 1722. It takes two main forms: 康熙年製 (Kangxi nian zhi), meaning "Made in the Kangxi reign," and 康熙御製 (Kangxi yuzhi), meaning "Made by Imperial Order of the Kangxi Emperor."
• Genuine Kangxi period four-character marks are rare. The standard imperial mark of the reign has six characters, 大清康熙年製 (Da Qing Kangxi nian zhi), meaning "Made in the Kangxi reign of the Great Qing dynasty." The four-character form drops the two characters that name the dynasty.
• Most four-character Kangxi marks a reader will meet are later pieces. According to the specialist reference Gotheborg.com, genuine four-character Kangxi nian zhi marks occur only inside a double-line square border and only on palace workshop decorated wares, while unbordered four-character marks are generally from the Guangxu period of 1875 to 1908 or later.
• A mark alone never proves a date. Chinese potters copied earlier reign marks for centuries out of respect for admired periods, and such apocryphal marks were not always meant to deceive. Museums and specialists judge the porcelain itself: the body, the glaze, the foot, the cobalt blue, the painting, and the calligraphy of the mark.

What a Kangxi Four-Character Mark Is

A Kangxi four-character mark is a short inscription written on the base of a piece of Chinese porcelain. It has four Chinese characters, and it names the Kangxi Emperor, who ruled China from 1661 to 1722. The mark is a reign mark, a form of dating inscription that records the dynasty and the emperor in whose reign a piece was supposedly made. Christie’s describes a reign mark as a record of the dynasty and the emperor during whose reign the piece was made, usually found on the base of a work of art commissioned for the emperor or his imperial household.

The phrase “Kangxi 4 character mark” is how collectors and searchers usually write it, but the mark itself is always in Chinese characters, never in English. It is most often written in underglaze cobalt blue, which is painted onto the porcelain body before the glaze is applied and fired, so the blue sits under a clear glaze. It can also appear in enamels over the glaze, in iron red, in gilt, or incised into the clay. It is usually found in the center of the base, and it is usually enclosed in a double circle or a double square, though unframed examples exist.

The Kangxi reign is one of the most admired periods in the whole history of Chinese porcelain. The Kangxi Emperor reigned for 61 years, the longest reign of any emperor in Chinese history, and his reign opened the High Qing era, a period of stability and prosperity after years of war. The imperial kilns at Jingdezhen in Jiangxi province produced porcelain of exceptional quality during his reign, including blue and white wares, famille verte enamels, and the copper red glazes known as peachbloom. Because Kangxi porcelain is so admired, its marks have been copied more than those of almost any other reign, and that is the first thing a reader needs to understand: finding the words “Kangxi” on a base is the start of the question, not the answer.

The Two Readings: Nian Zhi and Yuzhi

A four-character Kangxi mark can read in two ways, and the difference matters, because the two readings point to different kinds of pieces.

The first reading is 康熙年製, pronounced Kangxi nian zhi. The first two characters, 康熙 (Kangxi), are the era name of the emperor. The last two characters, 年製 (nian zhi), form a standard formula meaning “made in the period of.” Put together, the mark reads “Made in the Kangxi reign.” This is the four-character version of the ordinary imperial reign mark. Christie’s collecting guide states the rule plainly: four-character reign marks simply omit the first two characters recording the name of the dynasty, so the six-character mark 大清康熙年製 (Da Qing Kangxi nian zhi) becomes the four-character mark 康熙年製 (Kangxi nian zhi) when the words “Great Qing” are left out.

The second reading is 康熙御製, pronounced Kangxi yuzhi. The first two characters are the same, but the last two, 御製 (yuzhi), mean “made by imperial order” or “made for the emperor.” Christie’s translates the phrase as “Made by Imperial Order of the Kangxi Emperor.” A yuzhi mark is a stronger claim than a nian zhi mark. It says the piece was made to the emperor’s own order, not simply during his reign, and it appears on a small group of exceptionally fine wares. Christie’s records an imperial blue-ground falangcai bowl with a four-character Kangxi yuzhi mark in ruby-red enamel within a double square, and a painted enamel lotus vase with the same mark in blue enamel within a double circle. Both are described as exceedingly rare, and both belong to the palace workshop wares discussed later in this article.

A reader who finds a four-character Kangxi mark should therefore ask which of the two readings it carries. If the last two characters are 年製, it is a nian zhi mark. If they are 御製, it is a yuzhi mark. The distinction is visible even to a reader who knows no Chinese, once the two pairs of characters have been compared side by side in a reference book.

How to Read the Mark, Character by Character

Reign marks follow a fixed layout, and learning it is the fastest way to read any Chinese porcelain mark. A six-character mark is usually written in two vertical columns of three characters. The columns are read from top to bottom, starting with the right-hand column. A four-character mark is usually written in two columns of two, read the same way: right column first, top to bottom, then left column. A mark written in a single horizontal line is read from right to left. Christie’s explains that this system is thought to have grown from ancient Chinese traditions of writing on vertical strips of bamboo or bone.

Read in order, a six-character Kangxi mark breaks down as follows. The first two characters, 大清 (Da Qing), mean “Great Qing” and name the dynasty. The middle two, 康熙 (Kangxi), are the era name of the emperor. The last two, 年製 (nian zhi), mean “made in the period of.” A four-character mark drops the dynasty and keeps the era name and the formula, so it reads Kangxi, then nian zhi.

Two scripts are used for reign marks, and they look very different. Kaishu, or regular script, is the ordinary handwriting style most people associate with Chinese writing. It was introduced in China during the Sui dynasty of 581 to 618 and the Tang dynasty of 618 to 906, according to Christie’s. Zhuanshu, or seal script, is a much more angular and archaic-looking style that originated on ancient bronzes of the Shang and Zhou dynasties. Genuine Kangxi period marks are written in kaishu. The specialist reference Gotheborg.com states that, as far as its author has been able to confirm, seal script marks do not occur on genuine Kangxi period pieces, and Christie’s notes that seal script marks found favor later, during the Yongzheng period of 1723 to 1735 and after. A Kangxi mark written in seal script is therefore a reason for caution, not a proof of age.

The characters themselves also carry a warning. Kaishu is writing, and it shows the habits of an individual hand, which makes it hard to copy well. Zhuanshu is closer to drawing, with fixed and stylized forms, which makes it easier to copy. That is one reason specialists pay close attention to the calligraphy of a mark: a genuine imperial mark was written by one of a small number of trusted hands, and experts can sometimes recognize the individual handwriting.

Four Characters or Six: How the Two Marks Differ

The six-character mark is the normal imperial mark of the Kangxi reign, and it is the form a reader is most likely to see on a genuine Kangxi period piece. The Metropolitan Museum of Art, for example, holds a Kangxi period vase whose base carries a six-character inscription reading Da Qing Kangxi nian zhi; the museum’s essay on the piece notes the style of the writing suggests the years 1678 to 1688, although the museum’s object record dates the vase 1713 to 1722. The museum labels such pieces “Kangxi mark and period,” meaning that both the mark and the piece belong to the reign.

The four-character mark is the exception, not the rule, and that is the central fact of this article. Gotheborg.com, the standard online reference for Chinese porcelain marks, states the rule in plain terms: all genuine Kangxi period marks should be of six characters, and the only genuine four-character Kangxi nian zhi marks are those done within a double-line square border and used exclusively for palace workshop decorated wares, the highest level of imperial porcelain. All four-character Kangxi marks without borders, the same source states, are from around the Guangxu period of 1875 to 1908, when four-character kaishu marks were widely used.

That rule is stated strongly, and it is worth treating as a working rule rather than a law of nature. Other specialists have pointed out that many four-character Kangxi marks exist on imperial wares illustrated in Palace Museum publications, and that exceptions may exist. But the broad picture is not in dispute: genuine period four-character marks are rare, they belong to a narrow class of palace workshop wares, and the great majority of unbordered four-character Kangxi marks a reader will meet are later pieces. A four-character mark without a border should therefore be read as a later mark until the porcelain itself proves otherwise.

The yuzhi marks are a partial exception to the rule, and they show why the subject needs care. Christie’s records genuine Kangxi period yuzhi marks in double circles as well as double squares, on painted enamel wares made in the palace workshops. The double circle that frames a yuzhi mark is not the same as an unbordered nian zhi mark, and the wares that carry yuzhi marks are a distinct and exceptionally rare group. The two readings, nian zhi and yuzhi, have different histories, and they should not be confused.

The Kangxi Emperor and the Porcelain of His Reign

Kangxi was born Xuanye on 4 May 1654 in Beijing, the son of the Shunzhi Emperor. He came to the throne in 1661 at the age of seven, after his father’s death, and power was held at first by four regents and his grandmother, the Dowager Empress Xiao Zhuang. He took personal control in 1669, when he had the regent Oboi arrested at the age of 15. He reigned until his death on 20 December 1722, a reign of 61 years that remains the longest of any emperor in Chinese history. The era name Kangxi, which is usually translated as peaceful harmony, was used from 1662, which is why museums date Kangxi porcelain to 1662 to 1722 even though his reign began in 1661.

Kangxi was a scholar as well as a soldier. He campaigned in the north and west, including in the Mongolian lands described in our guide to China’s Inner Mongolia, and he annexed Taiwan in 1684. He also sponsored learning on a large scale, and the great Kangxi Dictionary, a standard reference for the Chinese script, was compiled under his patronage and completed in 1716. His court valued the arts, and porcelain was among the arts he patronized most closely.

The porcelain of his reign was made at Jingdezhen, a town in Jiangxi province that had been the center of Chinese porcelain production for centuries. The imperial kilns there made wares for the court, while the many private kilns of the town made wares for merchants, officials, and export. The distinction matters, because imperial wares, known as guanyao or official ware, and private kiln wares, known as minyao or the ware of the people, were made to different standards and carried different marks. Christie’s notes that the quality of genuine reign marks varies, but on pieces specially commissioned for the emperor the mark should be of the highest caliber, matching the finesse of the work itself, while lesser quality ceramics made during the reign but not for imperial use often carry less well executed marks.

The early Kangxi years were difficult for the kilns. Jingdezhen had been damaged in the wars that brought the Qing dynasty to power, and production had to be rebuilt. According to Sotheby’s, the official Zang Yingxuan was sent to Jingdezhen in 1681 to oversee the rebuilding of the kilns and to serve as imperial supervisor, and the famous peachbloom group of copper red wares was produced in the early years of the reign under his supervision. The Met holds several peachbloom pieces dated to 1678 to 1688, including a water jar with incised decoration under a peachbloom glaze, which shows how quickly the kilns recovered.

The reign also saw new techniques arrive at court. European enamel techniques were introduced into the Qing court in the 1680s, and by 1693 the Kangxi Emperor had established 14 new technical workshops within the Forbidden City in Beijing, including a dedicated workshop for painted enamels, known as falangcai. Christie’s records that the bodies of falangcai pieces were thrown and fired at the imperial kilns in Jingdezhen, but their painted enamel decoration was completed in Beijing, in the palace workshops. It is on these palace workshop wares that the four-character yuzhi marks appear, which is why the marks and the wares belong together in any account of the subject.

Genuine Period Marks and Apocryphal Marks

The most important idea in Chinese porcelain marks is the apocryphal mark, and it is also the most misunderstood. An apocryphal mark is a reign mark that names an earlier reign than the one in which the piece was made. For hundreds of years, Chinese potters copied the marks of earlier reigns out of respect and reverence for those periods. Christie’s states this plainly: such marks were not necessarily intended to fool buyers into thinking they were buying an earlier work of art. A later piece with an earlier mark can be an honest tribute, a workshop following a revered model, or a deliberate fake, and the mark alone cannot tell a reader which of the three it is.

The practice began early. In the early Kangxi period, potters still used the six-character mark of the Ming emperor Chenghua, who reigned from 1465 to 1487, and occasionally that of the Jiajing Emperor. Christie’s gives the same picture: it is not uncommon to find 15th-century Ming dynasty reign marks on Qing dynasty blue and white porcelain made in the Kangxi period. The two most copied apocryphal marks, according to Christie’s, are those of the Xuande period of 1426 to 1435 and the Chenghua period, both famed for the quality of their imperial porcelain. Toward the end of the Kangxi reign, the Kangxi six-character kaishu mark became the one in general use, according to Gotheborg.com.

The Kangxi Emperor himself intervened in the use of marks. In 1667, according to Christie’s, he issued an edict forbidding the use of his reign mark on porcelain, in case the ceramics were smashed and discarded, which would have meant destroying the imperial name. The result was that many porcelain marks of the period consist simply of empty underglaze blue double circles, or of auspicious symbols in underglaze blue, such as an artemisia leaf, a lingzhi mushroom, or the head of a ruyi scepter. Gotheborg.com records a similar point: during the Kangxi period, the habit of adding reign marks to porcelain not commissioned by the emperor was addressed and forbidden by public edicts. A Kangxi period piece with no mark at all, or with only a double circle, is therefore entirely normal, and an unmarked piece is not automatically a lesser piece.

The later history of the four-character mark runs in the other direction. Gotheborg.com states that Kangxi marks seem not to have been copied during the 18th century, possibly because the Yongzheng and Qianlong emperors were concerned with their own image and regarded their own porcelain designs as superior. The copying came later. In the Guangxu period of 1875 to 1908, four-character kaishu marks were widely used, and many pieces bearing four-character Kangxi marks date from that period or from the 20th century. Collectors discussing the subject have noted the same pattern: a four-character underglaze blue Kangxi mark on an ordinary dish is most likely to belong to a piece made for export in the late 19th or early 20th century, when Chinese domestic porcelain consumption was driving the practice of adding apocryphal marks of a favorite earlier emperor to the base.

How Museums and Specialists Judge a Piece

A reign mark is one piece of evidence, and specialists treat it as the least decisive piece on its own. Gotheborg.com states the position clearly: since around 1995 there has been a rise in computer-aided designs, and no mark can be trusted any more as the single feature on which to base any judgment of authenticity. Overall style and quality should be the true criteria.

The first thing a specialist examines is the porcelain body and the glaze. Kangxi porcelain is finely potted, with a smooth white body and a clear glaze. The throwing of the body matters as much as the glaze: wheel-thrown porcelain has an even wall and a regular foot, while hand building pottery techniques leave different marks in the clay, so the way a piece was formed is itself part of the evidence. The foot, the unglazed ring on the base where the piece stood in the kiln, is often carefully finished. The cobalt blue used in Kangxi blue and white wares is a deep sapphire color, clear and bright rather than muddy or gray. The painting is confident and well drawn, with fine lines and controlled washes. A piece that looks coarse, heavy, or carelessly painted is unlikely to be a Kangxi period piece, whatever its mark says.

The second thing is the calligraphy of the mark itself. Sir Harry Garner, the scholar cited by Gotheborg.com, suggested that Kangxi marks could be divided into three chronological groups on the basis of their calligraphy: early period marks are bold; middle period marks are freely written and rather loose; and late period marks are precise, tight, rather small, and less free than the other two groups, occurring especially on small pieces of superb quality such as peachbloom wares and the small cups known as month’s cups. The Metropolitan Museum of Art’s essay on its Kangxi vase notes that the style of the writing suggests the years 1678 to 1688, although the museum’s object record dates the vase 1713 to 1722, so the dating rests on exactly this kind of reasoning: the style of the writing helps to date the piece within the reign. A mark that is stiff, uneven, or drawn rather than written is a warning sign, because a genuine mark was written quickly and confidently by a practiced hand.

The third thing is the fit between the mark and the piece. A mark of the highest quality should sit on a piece of the highest quality. Christie’s makes the point directly: a poorly written mark on a ceramic intended for the emperor should raise alarm bells, while less well-executed marks are expected on lesser quality ceramics made for ordinary use. A superb mark on a coarse body, or a crude mark on a superb body, is an inconsistency that needs explaining.

The fourth thing is the shape, the decoration, and the palette. Certain forms and palettes belong to certain periods, and a specialist checks whether the decoration matches the reign the mark names. Famille verte enamels, for example, are characteristic of the Kangxi period, while the famille rose palette, with its opaque pink enamels, belongs to the following reigns. A piece painted in famille rose but carrying a Kangxi mark is a later piece, however well the mark is written.

Finally, specialists check the record. Museum collections provide the reference points: the Met, the British Museum, and the Victoria and Albert Museum all hold Kangxi period porcelain with published descriptions, and the British Museum’s collection includes Kangxi dishes made at Jingdezhen. Auction houses publish detailed lot essays with photographs of marks, and reference books such as Gerald Davison’s Marks on Chinese Ceramics, published in 2021 and listing around 4,200 marks, give a reader the means to compare a mark against documented examples. No single comparison settles a question, but a mark that matches no documented genuine example is a serious problem.

Kangxi Porcelain Styles You Will Meet

A reader meeting Kangxi porcelain will usually meet one of a small number of styles, and knowing them helps to place a mark in context.

Blue and white porcelain is the best known. Cobalt blue is painted under a clear glaze, and Kangxi blue and white is admired for the depth and clarity of its blue and for the freedom of its painting. Landscapes, figures, flowers, and animals are common subjects. Most Kangxi export porcelain, the ware made for sale overseas, is blue and white, and most of it is unmarked. The Asian Art forum discussion of four-character marks notes that there is no indication that the use of Kangxi markings of either kind was the rule for export wares, which means a blue and white export piece with a Kangxi mark deserves a second look rather than instant belief.

Famille verte, meaning “green family,” is the overglaze enamel palette of the Kangxi period. Enamels in green, red, yellow, aubergine, and black are painted over the glaze and fired at a lower temperature. The effect is closer to a picture built up from small patches of color, the same principle behind mosaic painting, than to a single wash of glaze. The Victoria and Albert Museum holds a Kangxi period famille verte dish painted with a scene from the drama The West Chamber, which shows the palette at its most narrative and detailed.

Peachbloom is the name collectors give to the copper red monochrome glazes of the Kangxi reign. The glaze is a soft pinkish red, said to imitate the skin of a ripening peach, and it appears on a small group of vessels for the scholar’s table in eight different shapes, including the beehive-shaped waterpots known as taibai zun. Copper red glazes had been largely abandoned at Jingdezhen since the early Ming dynasty and were revived and improved only during the Kangxi reign, according to Sotheby’s. The Met’s peachbloom water jar of 1678 to 1688 is a typical example.

Monochrome glazes more generally are a hallmark of the reign: pale celadon greens, deep sacrificial blues, mirror blacks, and yellow glazes all appear on Kangxi wares. The Victoria and Albert Museum holds a Kangxi dish decorated with dragons on a yellow ground, made at Jingdezhen, which shows the monochrome tradition at its most confident.

Falangcai, the painted enamels made in the palace workshops, are the rarest and most refined of all. Their bodies were made at Jingdezhen and their decoration was completed in Beijing, and they carry the yuzhi marks discussed above. A falangcai piece is a palace object in the fullest sense, and genuine examples are counted in small numbers in museums and in the published record.

Common Fakes and Pitfalls

The most common pitfall is the simplest: assuming that a Kangxi mark means a Kangxi date. It does not. The mark records what was written on a piece, not when the piece was made, and for most of the pieces a reader will meet, the two are different. The majority of pieces bearing Kangxi, Yongzheng, or Qianlong marks are not from those reigns.

The second pitfall is the seal script Kangxi mark. As noted above, seal script marks are not confirmed on genuine Kangxi period pieces, and they became fashionable only from the Yongzheng period onward. A Kangxi mark in seal script is almost certainly later, and a dealer or seller who presents it as a period mark should be asked for a fuller explanation.

The third pitfall is the unbordered four-character mark on an ordinary piece. A four-character Kangxi nian zhi mark without a double-line square border, on a dish or bowl of ordinary quality, is most likely a Guangxu period or 20th-century piece. The border matters: it is the feature that separates the rare genuine palace workshop examples from the common later ones.

The fourth pitfall is the modern fake. Since the mid-1990s, computer-aided designs have made it possible to reproduce reign marks with a precision that hand copying could never achieve, and Gotheborg.com warns that no mark can now be trusted as the single basis for a judgment of authenticity. A mark that looks too perfect, too regular, or too mechanically even deserves suspicion, because genuine marks were written by hand and show the small irregularities of handwriting.

The fifth pitfall is the export piece with an English mark. After 1891, goods imported into the United States had to be marked with their country of origin in English, and later pieces often carry the words “China” or “Made in China” alongside or instead of a Chinese mark. A piece that carries both a Kangxi reign mark and an English country-of-origin mark is a later export piece, not a Kangxi period one.

The sixth pitfall is to ignore the porcelain and trust the mark. The body, the glaze, the foot, the weight, and the painting are harder to fake than a few characters on a base, and they are where specialists start. A reader who cannot judge those features should not buy on the strength of a mark alone.

Where to See Genuine Kangxi Porcelain

The best way to learn what genuine Kangxi porcelain looks like is to look at it in a museum, where the pieces have been studied and published. The Metropolitan Museum of Art in New York holds a strong collection of Kangxi porcelain, including peachbloom-glazed vases and water jars made at Jingdezhen, with object records that give dates, mediums, and credit lines. The British Museum in London holds Kangxi dishes and vases made at Jingdezhen, including pieces from the Sir Percival David Collection, one of the great collections of Chinese ceramics. The Victoria and Albert Museum in London holds Kangxi famille verte dishes and monochrome wares, with published accession numbers and descriptions.

Smaller collections are worth visiting too. The Burrell Collection in Glasgow holds Kangxi blue and white vases and monochrome wares, and the Palace Museum in Beijing and the Shanghai Museum hold related examples of the rarest palace workshop pieces, including the falangcai bowls with yuzhi marks that Christie’s cites as comparisons. If you want to compare collections, our guide to the biggest museum in the world explains how the largest museums are measured and what each of them holds.

Seeing genuine pieces in person teaches what photographs cannot: the weight of a well potted vase, the depth of a peachbloom glaze, the crispness of a well written mark, and the difference between a glaze that has aged for 300 years and one that was made to look old. A reader who plans to collect should spend time in museum galleries before spending money in shops or salerooms.

What to Do If You Own a Piece With This Mark

Start by looking, not by assuming. Read the mark using the layout described above, and note whether it is a nian zhi mark or a yuzhi mark, whether it is written in regular script or seal script, and whether it sits inside a double circle, a double square, or no border at all. Photograph the base in clear light, and photograph the whole piece, including the foot and any damage.

Then look at the piece itself. Is the body fine and white, or coarse and gray? Is the glaze clear and smooth, or cloudy and uneven? Is the painting confident or hesitant? Is the foot carefully finished? Compare what you see with published museum pieces of the same form, and be honest about the differences.

Do not clean the piece aggressively, and do not try to remove staining or wear from the base, since the condition of the base and the foot is part of the evidence. Keep any paperwork that came with the piece, including receipts, old labels, and previous descriptions, since provenance is part of how specialists judge an object.

If you want an opinion on a piece, take it to a specialist: a museum curator, an auction house Asian art department, or an independent appraiser who specializes in Chinese ceramics. Authentication needs handling the piece, examining it under magnification, and comparing it with known examples, and none of that can be done from a photograph alone. This article cannot authenticate a piece, and it gives no valuation, because values vary by piece, by condition, and by market, and a mark is only one part of the evidence.

Handle porcelain with care in the meantime. Hold a piece with two hands, support the base, keep it away from the edge of tables and shelves, and store it where it cannot be knocked. Porcelain that has survived for 300 years deserves another 300, and careful handling is the cheapest form of preservation.

FAQ

What does a Kangxi four-character mark say?

A Kangxi four-character mark reads either 康熙年製 (Kangxi nian zhi), meaning “Made in the Kangxi reign,” or 康熙御製 (Kangxi yuzhi), meaning “Made by Imperial Order of the Kangxi Emperor.” The first is the ordinary four-character reign mark. The second is a rarer mark used on palace workshop wares made to the emperor’s own order.

What is the difference between a four-character and a six-character Kangxi mark?

A six-character mark reads 大清康熙年製 (Da Qing Kangxi nian zhi), meaning “Made in the Kangxi reign of the Great Qing dynasty.” A four-character mark drops the first two characters, 大清 (Da Qing), which name the dynasty, and keeps the era name and the formula. The six-character form is the standard imperial mark of the reign, and genuine Kangxi period pieces normally carry it. Genuine period four-character marks are rare and belong mainly to palace workshop wares.

Does a Kangxi mark mean the piece was made during the Kangxi reign?

No. A reign mark records what was written on a piece, not when the piece was made. Chinese potters copied earlier reign marks for centuries, out of respect for admired periods and sometimes to mislead buyers. Such marks are called apocryphal marks. Most pieces bearing Kangxi marks were made later, often in the 19th or 20th century, so the mark must be judged together with the body, the glaze, the painting, and the calligraphy.

Are four-character Kangxi marks rare?

Genuine Kangxi period four-character marks are rare. According to the specialist reference Gotheborg.com, genuine four-character Kangxi nian zhi marks occur only inside a double-line square border and only on palace workshop decorated wares. Four-character yuzhi marks on painted enamel palace wares are also rare. But four-character Kangxi marks as a whole are common, because later pieces, especially from the Guangxu period of 1875 to 1908 and the 20th century, very often carry them.

What is a Kangxi yuzhi mark?

A Kangxi yuzhi mark reads 康熙御製 (Kangxi yuzhi) and means “Made by Imperial Order of the Kangxi Emperor.” It appears on a small group of exceptionally fine palace workshop wares, including painted enamel falangcai bowls and vases. Christie’s records examples in ruby-red enamel within a double square and in blue enamel within a double circle. A yuzhi mark is a stronger claim than an ordinary nian zhi mark, and genuine examples are exceedingly rare.

What does apocryphal mean in Chinese porcelain?

An apocryphal mark is a reign mark that names an earlier reign than the one in which the piece was made. Chinese artisans copied the marks of admired earlier reigns for hundreds of years, often out of respect rather than to deceive. The most copied apocryphal marks are those of the Xuande period of 1426 to 1435 and the Chenghua period of 1465 to 1487. An apocryphal mark does not automatically make a piece a fake, but it does mean the mark cannot be used to date the piece.

How can you tell a fake Kangxi mark?

No single test is enough, and a mark alone never proves a date. Warning signs include a Kangxi mark written in seal script, which is not confirmed on genuine Kangxi period pieces; a four-character mark without a border on an ordinary piece; a mark that looks mechanically perfect, which may have been made with computer-aided design; a mark combined with an English “Made in China” stamp; and a poorly written mark on a piece claimed to be imperial. The porcelain itself matters more than the mark: the body, the glaze, the foot, the cobalt, and the painting must all match the reign the mark names.

Did Kangxi export porcelain carry reign marks?

Most Kangxi export porcelain is unmarked. Reign marks were used mainly on wares made for the court and the imperial household, and there is no indication that marking was the rule for export wares. In 1667 the Kangxi Emperor issued an edict forbidding the use of his reign mark on porcelain, and many pieces of the period carry only an empty double circle or an auspicious symbol instead of a mark. An export piece that carries a Kangxi mark therefore deserves careful examination rather than instant belief.

What is the Kangxi period?

The Kangxi period is the reign of the Kangxi Emperor, dated by museums to 1662 to 1722. Kangxi came to the throne in 1661 at the age of seven, and the era name Kangxi was used from 1662. He reigned for 61 years until his death in 1722, the longest reign of any emperor in Chinese history. The Qing dynasty, of which he was the second emperor to rule over China, lasted from 1644 to 1911.

Where can I see genuine Kangxi porcelain?

The Metropolitan Museum of Art in New York, the British Museum in London, and the Victoria and Albert Museum in London all hold published collections of Kangxi period porcelain made at Jingdezhen, including blue and white wares, famille verte dishes, and peachbloom-glazed pieces. The Palace Museum in Beijing and the Shanghai Museum hold related examples of the rarest palace workshop wares. Museum galleries are the best place to learn what genuine Kangxi porcelain looks like before judging any single piece.
