How can I tell if a pottery piece is a reproduction?

Look at the base first. Marks, glaze, and the bottom of a piece often reveal more than the decoration. Many reproductions have marks that are slightly off in size, shape, or spelling, or that appear crisp and new on a piece claimed to be old. Fake marks are sometimes applied to unmarked pieces.

Check weight, glaze, and detail. Reproductions may be heavier or lighter than originals, show blurrier molded details, or have glaze colors that are close but not quite right. Wear on the base should look natural, not uniformly scratched.

Compare with documented examples from reference books or reputable collector resources. Pottery collectors often know the subtle differences between original production and later copies. If a piece may be valuable, ask a specialist dealer or an appraiser who handles pottery to examine it before buying or selling.
