A guide to dating Wedgwood ceramics over the last 250 years

Dating old pottery is difficult - especially one that has been in operation for over 200 years such as Wedgwood.

Manufacturers were not overly concerned about sticking to 'rules' and would interchange marks - using different marks at the same time and using old batches later in the production runs.

This information has been culled from a number of sources - it is given in good faith and believed to be reasonably correct - however if you are going to use it for the basis of valuations, purchases or sales then you must verify it from independent, qualified sources. *
