Turn over a plate, cup or figurine and you will often find a mark on the base. That small stamp or signature can tell you who made the piece, where it came from, and roughly when. It can also mislead you, because famous marks have been copied for centuries. This guide explains how to read a mark and how far to trust it.
Types of marks
How a mark was applied is the first clue. Look closely, ideally with a magnifier and good light.
- Impressed marks are pressed into the soft clay before firing, leaving a recessed name, number or symbol. You can feel them with a fingertip. They're common on earthenware and stoneware, for example the impressed "WEDGWOOD" found on that firm's wares.
- Printed marks were applied by transfer or stamp. Some sit under the glaze, so they look sealed in and won't wear off. Others sit over the glaze and can be worn or felt slightly raised.
- Painted marks were added by hand with a brush. They vary from piece to piece because each was painted individually. The Meissen crossed swords and many Chinese reign marks are painted.
- Incised marks are scratched into the clay by hand, often as a signature on studio pottery.
Many pieces carry several marks: a factory mark, a pattern name or number, a decorator's mark, and sometimes a retailer's mark. A missing mark doesn't prove a piece is late or worthless. Plenty of early pottery was never marked at all.
What country names tell you
Country-of-origin wording is one of the most useful dating tools, because it was often added in response to import laws.
| Wording on the mark | What it usually suggests |
|---|---|
| No country name | Often made before 1891, or for the home market, but not proof of age |
| Country name alone, such as "England" or "Bavaria" | Usually 1891 or later |
| "Made in England" or another "Made in…" | Usually 20th century, most often from around the 1910s onward |
| "Nippon" | Japanese, made for export roughly 1891 to 1921 |
| "Japan" or "Made in Japan" | Usually 1921 or later |
| "Occupied Japan" or "Made in Occupied Japan" | The Allied occupation, roughly 1945 to 1952 |
| "West Germany" | After 1949 and before reunification in 1990 |
The 1891 date comes from the United States McKinley Tariff Act, which required imported goods to be marked with their country of origin. Many European and Japanese makers began adding country names around then. The fuller "Made in…" phrasing became common in the early 20th century. In 1921, US customs ruled that "Nippon" was a Japanese word rather than the English name of the country, so Japanese exports were marked "Japan" from then on.
Treat these as rules of thumb, not exact dates. Some makers adopted the wording earlier or later, and pieces made for a domestic market may never carry a country name.
Common makers and their marks
Wedgwood
Founded by Josiah Wedgwood in 1759, the firm used an impressed "WEDGWOOD" mark on much of its pottery, including the well-known jasperware. "ENGLAND" was added around 1891, and "MADE IN ENGLAND" appeared in the 20th century. Many Wedgwood pieces from 1860 also carry impressed three-letter date codes, which reference books can decode. Be aware that the similar-looking "WEDGEWOOD" spelling, with an extra E, was used by other makers.
Meissen
The Meissen factory near Dresden in Germany was the first in Europe to make true hard-paste porcelain, in the early 18th century. Its crossed swords mark, painted in underglaze blue, has been used since the 1720s, with variations over the years that specialists use for dating. It is one of the most copied marks in the world. "Dresden" on a mark usually points to one of the many other factories and decorating studios in the area, not to Meissen itself.
Royal Doulton
Doulton & Co. was a major English pottery. The "Royal Doulton" name and the familiar lion-on-crown mark came into use after the company received a royal warrant in 1901. Many Royal Doulton figurines also carry an "HN" number, which identifies the model.
Noritake
Noritake is a Japanese maker whose company roots go back to the early 20th century. Its export porcelain is a good example of the country-name rule: older pieces are often marked "Nippon", later ones "Japan". Noritake used many different backstamps over the years, including the well-known "M in a wreath" mark associated with the Morimura Brothers trading company.
Royal Copenhagen
The Danish factory, founded in the 1770s, marks its porcelain with three wavy lines, said to represent Denmark's three main waterways. A crown was added to the mark later. Its blue fluted and blue-and-white wares are especially well known.
Limoges
Limoges is a city and region in France, not a single company. Many factories worked there, including Haviland and Bernardaud, so "Limoges" on a mark tells you where the porcelain was made, not by whom. It is common to find two marks on one piece: an underglaze mark from the factory that made the white porcelain blank, and an overglaze mark from the studio or company that decorated it. Some pieces sold as "Limoges" were actually decorated by amateurs on imported blanks.
Fakes of famous marks
Valuable marks attract copyists. Some later factories made honest copies in an older style, while others added misleading marks on purpose. Widely imitated marks include the Meissen crossed swords, the Sèvres interlaced Ls, the shield mark associated with Vienna porcelain (often called the "beehive"), and Chinese reign marks, which were often added to later pieces as a mark of respect for earlier work, not always to deceive.
Warning signs include:
- A mark that looks too new. A crisp, bright mark on a piece that should be well over a century old deserves a second look.
- A mark in the wrong place or technique. For example, a mark sitting over the glaze where the genuine factory painted it under the glaze.
- Poor quality decoration. Smudged painting, blurred transfer printing or clumsy gilding rarely match a top factory's standard.
- No wear where there should be some. Old pieces used on tables usually show fine scratches and wear on the foot rim.
- Decal or sticker marks on a piece claimed to be early.
- Spelling mistakes or slightly altered names that imitate a famous maker.
Remember that a mark is only one piece of evidence. The clay or porcelain body, the glaze, the shape, the weight and the style of decoration should all agree with what the mark claims. If they don't, trust the object over the mark. Our guide on antique, vintage or reproduction covers more general signs of real age.
Looking up a mark
Once you have a clear photo of the mark, compare it with a good reference. Long-standing printed references include Geoffrey Godden's encyclopaedia of British pottery and porcelain marks and Kovels' guides to marks. Factory museums and collectors' clubs often publish mark charts for individual makers.
Tip: Photograph the mark straight on, with soft light from the side so impressed marks cast a shadow. AI Antique reads the whole object, not just the mark, and suggests a likely maker, country and period that you can then check against a reference.
Identifying the mark is only the first step towards a price. For valuable pieces, condition and recent sold prices matter just as much, as explained in how much is my antique worth.
