Are unmarked Chelsea pieces common, and how are they identified?

Unmarked Chelsea pieces appear frequently, and so the debate over copyright still remains. Even reference sources warn that distinguishing Chelsea from some of its close makers can be difficult, and after the 1770 Duesbury acquisition, overlap becomes apparent. Identification is then based on style families, paste tone, glaze appearance, and familiar forms from published Chelsea pieces. Painting reveals some of the history, but repainting is common, so surface examination is important. When looking for figures, note the quality of the modelling, the finish of the base, and how the enamels fit into the relief. For tableware, compare edge profiles, rim finish, and gilding.
