An iridescent periwinkle blue lusterware footed teacup and
Lusterware is a type of pottery characterized by a metallic iridescent glaze that creates a rainbow-like effect on the surface. This technique dates back to the Islamic world but became highly popular in European porcelain production during the 19th and early 20th centuries. The process involves applying a thin layer of metal oxides to a previously fired glaze and firing it again in a reducing atmosphere. Footed cups of this style were often used for specialty drinks like mocha or chocolate, reflecting the ornate tea culture of the mid-century period. The combination of pierced 'reticulated' edges on the saucer and iridescent glazes was a hallmark of decorative porcelain intended for display as much as for use. These pieces are now collected for their striking visual appeal and the technical skill required to achieve the luster effect.
