A fine 19th century Wedgwood teapot, this piece is in earthenware (apparently Queens Ware) glazed with Wedgwood version of a Rockingham glaze, which is a beautiful burgundy-purple color.
This glaze was introduced by Wedgwood at the Paris Exhibition of 1878. It remained in production until about 1911.
This teapot is similar to Wedgewood's #129 shape, but Robin Reilly claims that Rockingham was a shape name as well as a glaze name, so this piece may be in the "Rockingham" shape; it is marked ROCKINGHAM on the bottom.
The lid features Wedgwood's Sybil knob handle in the center, a design which goes back to the late 18th century.
The decoration is what Wedgwood called "Vigornian Ware". Robin Reilly describes this form of decoration as being acid-etched- with the patterns for the etchings having been designed by John Northwood, but close examination of this example strongly points to the decoration being wheel-cut (another common technique for decoration glass in the late 19th century). Close examination of the teapot in color plate C56 of Reilly's "Wedgwood" (volume II) suggests that the decoration on that pieces was achieved in the same way.
The initials "CD" are inter-twinned in the center of each side.
The pot is 6.75" tall and 7" from handle to spout.
Condition: glaze is crazed all over, inside and out. Slight roughness to the front edge of the spout. One very minor spot of glaze loss to the top edge of the Sibyl's cowl.
Marked WEDGWOOD on the bottom, this piece dates to 1878-1891.
