Lusterware is a type of pottery or porcelain with a metallic glaze that gives the effect of iridescence. The technique on pottery was first developed in Mesopotamia (modern Iraq) in the early 9th century. It is produced by metallic oxides in an overglaze finish, which is given a second firing at a lower temperature in a "muffle kiln", or a reduction kiln, excluding oxygen. The Lusterware effect is a final coating applied over the ceramic glaze, and fixed by a light second firing, applying small amounts of metallic compounds (generally of silver or copper) mixed with something to make it paintable (clay or ochre). This is then fired in a reducing atmosphere at a temperature high enough to "soften" the glaze from the first firing, and break down the metallic compounds, leaving a very thin ("perhaps 10 or 20 atoms thick") layer that is fused with the main glaze, but is mainly metal. Lusterware normally only uses one colour per piece, and the range is limited a "gold" derived from silver compounds was historically the most common. The process has always been expensive and rather unpredictable, always requiring two firings, and often the use of expensive materials such as silver and platinum. The very thin layer of luster is often delicate, and many types of Lusterware are easily damaged by scratching removing the metallic layer, or by contact with acids. Lusterware has therefore always been for display and occasional use, although by the 19th century it could be relatively cheap. Many pieces show the luster effect only working correctly on parts of the surface, or not at all.
