As happens with any successful idea or product, Josiah Wedgwood found that he had to face imitators after he created new wares at his pottery. Jasper and Black Basalt were the most heavily imitated, and the biggest group of imitators were the other Staffordshire potteries.
EJ Birch was one of these potters, know best know for his copies of Wedgwood's dry-body wares, especially Basalt, but also Caneware. he opened his pottery in 1796 and it closed in 1814.
This a creamer in a fairly well-known Birch form: a barrel shape with engine turning at the top and bottom and sprigged figural relief in the center. It dates to about 1800-1814. It would have originally been part of a tea or coffee service, but after 200 years, pieces have gone their separate ways, and it's rare to find even a partial set surviving together.
Size: It's 4" tall and 5" from handle to spout.
Condition: one small shallow chip on the side of the spout, otherwise fine. The body of the piece is finely pimpled all over, showing that Birch like all the imitators had manufacturing issues producing these sort of wares.
Mark: impressed "Birch" on the bottom. Initials at the base of the handle
