This style of Burleigh Ware mark dates from the 1930s onward.

Details

The circular mark with:

• “BURLEIGH” arched around the edge

• Central script-style monogram of the initials B & L

• “WARE”, “BURSLEM” and “ENGLAND”

…is the form introduced in the 1930s. It continued in use for several decades afterward (with some minor variations).

Key supporting points from pottery reference sources:

• The trade name “Burleigh Ware” became more widely used from the 1930s.

• Marks featuring the B & L initials in script format within a circular arrangement with “Burslem England” are specifically noted as introduced in the 1930s and used continuously thereafter.

• Earlier marks (pre-1930s) more commonly used globe devices, beehive motifs, or different arrangements of “Burgess & Leigh”.

There is no single exact year for this mark — it was a standard backstamp used over a long period starting in the 1930s. Exact dating of an individual piece would also depend on the pattern, any additional impressed numbers, or style of the item itself.
