Lusterware is a type of pottery or porcelain that has a shiny, metallic glaze. This glaze is created by adding metallic salts during the firing process, which gives the surface a reflective quality. Lusterware can come in various colors, often featuring iridescent effects that change with the angle of light. This decorative technique has been used since ancient times, with notable examples from the Islamic Golden Age and later in European ceramics during the 19th century. Lusterware is popular among collectors and is often used for decorative items like vases, plates, and bowls.
