How to read the bottom of your china.

The marks on the underside of a piece of china can tell you almost everything — who made it, when, where, and sometimes by whom. Knowing how to read them is the first step in figuring out what you've inherited.

Understanding Porcelain Marks

Reading the marks on inherited china

Porcelain marks are the identification system for fine china. A mark can tell you the factory of origin, the approximate date of production, the decorator, the form or model number, and sometimes the specific artist. Different eras and different countries used different marking conventions, so learning to recognize the categories is the first step in turning a piece over and knowing what you're looking at.

The four main types of marks

Most porcelain marks fall into four technical categories. Painted marks are applied by hand with a brush, usually in underglaze blue (painted before the final glaze and firing) or in overglaze enamel or gilt (painted on top of the glaze). Hand-painted marks are typical of 18th-century European porcelain and higher-end 19th-century pieces. They show slight variation from piece to piece because they are individually applied.

Impressed marks are pressed into the soft clay before firing and show as a recessed design. Wedgwood and early English pottery and porcelain commonly used impressed marks. Impressed date codes and maker names often appear alongside other marks. Printed marks are transferred onto the piece using a paper or metal transfer, producing a uniform, ink-like appearance. Printed marks dominate 19th- and 20th-century commercial porcelain. Molded marks are part of the mold itself and appear as raised designs on the underside — common on Belleek and some figurines.

How marks evolved over time

Early European porcelain makers used simple hand-painted marks, often in blue, derived from coats of arms or factory symbols. By the mid-19th century, industrial production had standardized printed marks, and factories began adding date codes, pattern numbers, and retailer marks. The late 19th century brought legal requirements for country-of-origin marks on exports, driven primarily by the US McKinley Tariff Act of 1891. This law, and its 1921 revision requiring "Made in" rather than just the country name, is one of the most useful tools for dating inherited china from this period.

Throughout the 20th century, marks became more elaborate — incorporating factory logos, pattern names, decorator initials, and series information. Modern marks often include website addresses or copyright notices, which can be used to identify recent production. The history of the mark is, in a sense, the history of the factory.

European marks

European factories produced the most prestigious porcelain, and their marks are correspondingly well documented. The Meissen crossed swords (introduced around 1720) is the oldest continuously used porcelain trademark and has changed in documented ways over three centuries. KPM Berlin uses a scepter and, on decorated pieces, an orb with a cross. Sevres uses the interlaced L's of Louis XV. Vienna uses a beehive shield. Nymphenburg uses a shield. French Limoges factories — dozens of them — each have their own mark, often with additional decorator marks added separately. German Rosenthal, Hutschenreuther, and others each have distinct printed backstamps that changed by decade.

English marks

English porcelain makers developed sophisticated dating systems. Wedgwood used a three-letter impressed date code system starting in 1860. Royal Worcester used a system of dots around a central mark that changed annually. Royal Doulton applied a dated backstamp. Spode, Minton, Coalport, and Derby each had printed marks that evolved by era. English bone china from these major makers is generally dateable to within a few years based on the mark style alone.

American marks

American porcelain is a smaller but distinct category. Lenox, the major American fine china maker, used various wreath and palette marks through its history — including an early green wreath mark (1906-1924) that is the most desirable. Other American makers like Rookwood, Weller, and Roseville are classified as pottery rather than china, but carry similarly documented marking systems. American china production was smaller in scale than European or Asian, so the range of marks is narrower.

Asian marks

Asian porcelain marks are the most complex because they span more than a thousand years of production and include reign marks (imperial dating), factory marks, export marks, and decorator marks. Chinese reign marks in four or six characters identify the emperor during whose reign the piece was purportedly made — but the majority of reign marks found on inherited pieces are later copies or tributes, not genuine period marks. Japanese marks range from traditional calligraphic signatures to the English-language "Nippon," "Japan," and "Occupied Japan" marks required for export. Each era of Japanese porcelain marking has specific rules and value implications.

Common confusions

Several categories of marks trip up inheritors and general dealers alike. The Meissen crossed swords has been copied for centuries — many 19th-century German, French, and Asian factories produced wares with swords or sword-like marks that resemble Meissen but are not. The "Dresden" mark (often a crown over "Dresden") is a regional decorator designation, not a single factory — multiple studios in Dresden decorated blanks from other makers. Nippon vs. Made in Japan marks on otherwise similar pieces date them to very different periods and value tiers. Pattern numbers are not model numbers and vice versa. A specialist distinguishes these daily; recognizing the categories is the first step for an inheritor.

Quick Reference

  • Painted marks: High-end European, often 18th-19th century
  • Impressed marks: Wedgwood, early English wares
  • Printed marks: Most 19th-20th century commercial porcelain
  • Molded marks: Belleek, figurines, some art porcelain
  • Country alone: Typically 1891-1921
  • "Made in [country]": Typically post-1921

Photo Tip

Flip the piece over and photograph the mark straight on, in clear light. Include any additional numbers, letters, or symbols near the mark — these often carry dating or decorator information. If a mark is faint, try angling the piece under a bright lamp until the mark catches the light. Photograph each different mark separately rather than crowding them into one frame.

An Honest Take

What usually isn't valuable

A prestigious-looking mark does not automatically mean a piece is valuable. Here are the common situations where marks mislead inheritors.

Fake Meissen crossed swords

The Meissen crossed swords has been imitated more than any other porcelain mark. 19th-century German factories, French decorators, and Asian export makers all produced pieces with crossed-sword marks designed to suggest Meissen without quite copying it. Most inherited "Meissen" china is not genuine Meissen. The paste quality, painting precision, and mark style all need to match period-correct Meissen, not just the general shape of the swords.

Generic "Limoges" without a maker

"Limoges" refers to a region in France where many different factories produced porcelain — not a single company. A piece marked only "Limoges France" with no specific maker (like Haviland, T&V, or GDA) is typically a generic white-ware blank that was decorated commercially, often by an amateur painter. These pieces sell for modest amounts unless the painting is unusually fine.

"Dresden" decorator marks on plain blanks

Dresden crown marks indicate that a piece was decorated in Dresden by one of many studios that bought blank porcelain from other factories. The blanks themselves may be anything from fine Meissen to ordinary commercial ware. Without knowing the decorator and seeing the quality of the painting, a "Dresden" mark alone doesn't guarantee value, and many Dresden-decorated pieces are ordinary.

Post-1950 production with prestigious marks

Many famous factories — Meissen, Royal Doulton, Wedgwood, Herend — still produce china today. Modern marks from these factories appear on genuine porcelain but on current production, not antiques. A Meissen piece with a 1980s mark is worth a fraction of an 18th-century piece with the same crossed swords. The mark style itself, not just the name, determines the period.

Common Questions

Frequently asked about porcelain marks

Marks are almost always on the underside of the piece. On plates, bowls, and cups, flip the piece over and look at the center of the foot or the base. On pitchers, teapots, and vases, check the bottom. On figurines, marks are usually on the underside of the base, sometimes inside a hollow cavity. Some pieces also carry marks on the side of the foot ring. Use good light at an angle — marks often catch the light better when the piece is tilted. A magnifying glass helps with small or worn marks.
Country-of-origin marks help date the piece. The US McKinley Tariff Act of 1891 required imports to be marked with country of origin, so a piece marked only with a country name (like "Nippon" or "Germany") is generally from between 1891 and about 1921. The phrase "Made in" was required starting around 1921 in the US, so "Made in Germany" or "Made in Japan" typically indicates production after that date. "Occupied Japan" marks date pieces to 1945-1952. These rules are not absolute and vary by country, but country marks are a useful dating starting point.
Distinguishing genuine marks from copies requires examining the mark alongside the piece as a whole. Factors specialists consider include the quality of the paste (the porcelain body itself), the weight and feel of the piece, the quality of painting and gilding, the way the mark is executed (hand-painted, printed, or impressed), and the style details of the mark compared to documented examples for that period. Meissen crossed swords, Chinese reign marks, and Sevres marks have all been widely copied for centuries. The mark alone is never sufficient to confirm authenticity — it must match everything else about the piece.
Painted marks are applied with a brush, typically in underglaze blue or overglaze colors, and are common on high-end European porcelain like Meissen. Impressed marks are pressed into the clay before firing and create a recessed design — common on Wedgwood and early English wares. Printed marks are transferred from paper or metal and produce a very uniform, ink-like appearance — standard on most 19th and 20th century commercial porcelain. The type of mark is itself a clue to period and quality, since hand-painted marks generally indicate earlier or higher-end production.
Not necessarily. Some early porcelain — particularly 18th-century pieces made before marking became standard — is genuinely unmarked and can be very valuable. Some pieces also had marks ground off intentionally, sometimes to evade import duties or to disguise the maker. However, most unmarked china found in estates is simply unmarked commercial production with limited resale value. A specialist can often attribute unmarked pieces based on the paste, form, decoration, and style. If you think the piece looks old or well-made, it's worth having photos evaluated before assuming it has no value.
Turn the piece upside down on a stable surface. Use natural daylight or a bright lamp angled from the side rather than directly overhead. Get close — the mark should fill a large portion of the frame — and make sure it is in focus. If the mark is hard to see, try angling the piece under the light until the mark catches; sometimes turning it slightly reveals details that disappear from other angles. Photograph every different mark and any numbers or symbols separately. If there are multiple marks on the same piece, capture each one clearly rather than trying to fit them all into one shot.
