Staffordshire Pottery Identification Using Backstamps
The name of the pottery manufacturer and approximate date of manufacture can be discovered if the piece of pottery has a backstamp.There are way too many to list here as it would take a whole new website to list them all! The best reference book we have found is the Encyclopaedia of British Pottery and Porcelain Marks by Geoffrey A Godden and is probably the only book you will ever need. You can get a copy by clicking on the link below or alternatively your local library will probably have a copy in its reference section.

Registered Numbers
Registered numbers are a consecutive numbering system that started in 1884 for designs that were registered by companies. The Registered Number, usually written as Rd on the piece of pottery, gives the date when that design was registered to prevent copying, but it could have been made at any time later than that date.
Details of the registrations are held at the Public Record Office, Ruskin Avenue, Kew, Surrey. Telephone (0181) 8763444.
