Copper lustre mug with raised textured decoration

This copper lustre mug dates to the Victorian era, circa 1860, and was produced in England. The piece features a distinctive raised textured surface treatment with a copper-colored metallic glaze that creates a lustrous appearance, which was achieved by applying metallic oxides to the ceramic body. Copper lustre pottery became highly popular during the Victorian period as an affordable alternative to actual copper or silver vessels. These pieces are particularly valued by collectors of Victorian ceramics and decorative arts for their distinctive metallic sheen and craftsmanship. The textured surface on this example makes it especially interesting to collectors who appreciate unusual decorative techniques in 19th-century pottery.
