How to Read Ceramic Factory Marks Carefully

Identification GuidesDate Published
← All guides & stories

Factory marks can identify a maker, range or registration, but many changed over time and were copied or revived.

What to examine

Record the exact mark, colour, printing method and relationship to glaze. Compare with museum or factory archives, not a random image match.

Avoid the common trap

A genuine mark can appear on a later body or an altered object. Assess paste, glaze, decoration and wear together.

Record your findings

Photograph the whole object, the feature in context and a close-up with scale. Note what is observed separately from any conclusion.

Reliable starting points

  • [V&A collections](https://www.vam.ac.uk/collections)
  • [The Metropolitan Museum of Art: Heilbrunn Timeline](https://www.metmuseum.org/toah/)

Identification should combine several forms of evidence. Do not use destructive tests, and seek a specialist opinion where attribution or value matters.
