A lustreware goblet handmade by Jonathan Chiswell Jones, a UK-based ceramics artist. Designs vary slightly and each goblet is individually numbered and signed.
This luxury ceramic features an organic, leafy design. The design reflects light, and like oil on water, can break into iridescent colours.
Sometimes described as a modern alchemy, the lustreware process dates back ten centuries to potters of the Islamic empire, and has a fascinating history. To make lustreware pottery, silver and copper salts are mixed with clay and painted on the surface of the glazed pot. A third firing, in which the kiln is deprived of oxygen, deposits the metal in a minutely thin layer which combines with the glaze, creating the multicolour iridescent finish.
The goblet is vitrified (a glass-like substance) and fully waterproof. The lustre surface is vulnerable to abrasion so pots should be treated carefully if you want them in pristine condition - or used normally and enjoyed with their scars of honour. Dishwashing is not good for the lustre; clean with soap, water and a sponge.
