English: This small lustre-painted bowl was produced in Kashan, a city in central Iran known for its ceramic production between the 11th and 13th centuries. Kashan ceramics were made of fritware, a mixture of minerals (namely glass and clay).[1] They were painted over with lustre, which gives the ceramic surface a bright, metallic gleam.[2] Due to its flat base and wide rim, the shape of this bowl in the Aga Khan Museum Collection echoes the design of a metal vessel. The lustre also suggests the sheen of gold.
