How to identify antique pottery marks
A mark on the base can be your best clue—but it is only one part of identifying antique ceramics.
Start with the underside
Turn the piece over gently and inspect the foot ring, base, rim, and inside the lid. Makers may use printed backstamps, impressed names, painted initials, registration numbers, or a combination of these. A missing mark does not prove that a piece is old or unimportant.
Photograph marks clearly
Use diffuse daylight rather than flash. Take one full image of the object, then a close, sharp image of every mark. Photograph the shape, decoration, handles, and unglazed base too. Scale matters, so record height and width.
Read the clue in context
Compare the complete mark—not only a single letter—with documented examples. Look for the country of origin, factory name, pattern number, painter’s mark, or wording such as “Made in England.” The clay body, glaze, decoration style, and construction can help determine whether the mark fits the piece.
Watch for common traps
“Antique” is often used loosely in listings. A reproduction can carry a mark, and a mark may identify a manufacturer without dating an exact production year. Never rely on a single online listing as proof of value.
What to do next
Search museum collections, factory histories, auction archives, and specialist references for comparable examples. Use AntiqSnap to organize your photographs and generate research leads, then verify important finds with a ceramics specialist.
