Backstamps

A backstamp on a piece of ware can tell you much about a piece. Some backstamps can date the ware, such as the George S. Harker mark used from 1879 to 1890. Some describe a particular process, such as Cameoware, Pate sur Pate or Stone China.

Others were used to identify ware for jobbers, such as Harmony House and Columbia Chinaware. Using different backstamps would allow the pottery to convey a different meaning to the same piece of ware. The buyer might see ware with the Statue of Liberty Columbia Chinaware stamp as superior to ware with a Bakerite stamp.
