How to Identify Antique Pottery Marks
To identify a pottery mark, photograph the whole object and its complete mark, then compare the lettering, clay, glaze and shape with documented manufacturer and museum references. A recognizable symbol is a research lead, not proof of authenticity or age.
An actual pottery-mark scan, checked against references
On October 20, 2026, we sent this source photograph to the identification service used by AntiqSnap, using the app’s prompt with no maker or date supplied as notes. The text below is an actual result, not a staged device screenshot.
This appears to be a Royal Copenhagen porcelain plate with a printed commemorative backstamp for Hans H. Hansen and the title "Sol over Grønland / Sunshine over Greenland." It likely belongs to a collectible series or special edition decorative plate rather than everyday tableware.
| Question | Actual AI response | Reference check |
|---|---|---|
| Maker | The result names Royal Copenhagen. | Consistent with the visible stamp. The manufacturer’s backstamp reference explains the stamp and three-wave motif. |
| Date | 20th century | The photograph’s source labels the plate as 1958. The broad AI era is compatible with that label, but does not establish an exact year. |
| Title | Royal Copenhagen commemorative plate for Hans H. Hansen | The phrase “for Hans H. Hansen” is an interpretation, not a verified dedication. The photograph shows the name and design title; do not convert that wording into a commemorative attribution without evidence. |
The identification helps choose what to investigate. It does not verify condition, authenticity or a sale price. We have not treated generated price estimates or comparable-listing suggestions as actual market evidence.
Test method and source output
Actual identification-service response using the app’s prompt, English/USD, no user notes, original source JPEG. The app normally resizes large photographs, so device results can differ.
Read the captured response extracts. Source references and photograph credits appear beside the comparison above.
Find and photograph the evidence
Inspect the underside, foot ring, lid, and handles without scraping or polishing. Photograph the complete object first, then the base, every mark, and any damage. Use indirect daylight and take a second close-up with light from the side when lettering is impressed rather than printed. Keep the camera parallel to the mark and include its outline; a cropped letter can hide important context.
Write down height and width, the colors you see, whether the base is glazed, and exactly what the inscription says. Use a question mark for an uncertain character rather than guessing. For a partial mark, record the visible letters in order and note where the surface is worn.
Read a real backstamp photograph
The photograph shows why you should capture the whole underside: the green maker stamp, the blue marks, and the design wording occupy different parts of the base. Transcribe them separately. The visible maker name provides a starting point, but the design title and other lettering give additional details to investigate.
Do not turn every letter into a date code. Compare a complete mark with the appropriate manufacturer’s documented records before assigning a year, and check whether the material and design agree.
Separate the different kinds of marks
| What you see | What to investigate | What it cannot establish alone |
|---|---|---|
| Printed factory name or backstamp | Maker, factory location, documented stamp variations | An exact production date |
| Impressed letters in the clay | Maker name, workshop or production notation | Whether the piece is authentic |
| Painted initials or numbers | Painter, decorator, pattern or inventory notation | The meaning of an unexplained number |
| No visible mark | Form, body, glaze, decoration and provenance | That the object is old or worthless |
Documented examples to compare
The V&A describes the Chelsea anchor and Meissen crossed swords as familiar ceramic marks, while also noting that such marks were copied. Its discussion of A-marked porcelain shows that even museum researchers can have unresolved attributions. Compare your photograph with the illustrated collection examples in V&A: An A–Z of Ceramics; do not assign a maker from the symbol alone.
For a piece marked Wedgwood, start with the manufacturer’s history and the full inscription. The V&A records Josiah Wedgwood’s practice of stamping his wares. That history provides context, but a name alone does not identify a particular year or establish a price. See V&A: Wedgwood, an introduction.
Build a defensible identification
Keep a short record with three columns: observed detail, possible explanation, and source that supports it. Compare a similar shape and decoration, not just a matching word. If a source gives a date range, preserve that range rather than inventing a single year. When a proposed maker conflicts with the clay body or construction, leave the identification open.
A marketplace asking price is not a sale result. Before estimating resale value, compare condition, size, pattern, completeness, repairs, and documented sold examples. If the item may be valuable, a ceramics specialist can examine details that a photograph misses.
Use a photo identifier as a starting point
AntiqSnap accepts photos of ceramics and collectibles and provides possible identity, historical context, and estimated value information. Begin with a clear overall photograph, then compare the result against your mark close-up and reference sources. Treat uncertain text and authenticity as questions to verify.
Take this checklist with you
- Overall object, underside and complete mark photographed
- Dimensions and condition recorded
- Letters transcribed without guessing
- At least one documented maker reference checked
- Attribution and value uncertainties kept in the notes
Common questions
How do I identify a Royal Copenhagen backstamp?
Photograph the complete underside, including the crown stamp, lettering, blue waves and any painter’s marks. Compare the whole mark with the manufacturer’s documented backstamp reference; a symbol alone does not prove age or authenticity.
How do I identify pottery with no maker name?
Record the object’s shape, measurements, clay, glaze and decoration. Compare documented museum examples and provenance; an absent mark is not a reliable date test.
Can pottery be antique without a mark?
Yes. An absent mark is not a reliable date test. Research the object’s form, materials, decoration, and provenance as well.
Does a familiar logo prove authenticity?
No. The V&A documents copied ceramic marks. Check the object against reference examples and seek specialist examination for important purchases.
