Corelle is a brand ofglassware anddishware. It is made of Vitrelle, atempered glass product consisting of two types of glass laminated into three layers.[3][4] It was introduced byCorning Glass Works in 1970, but is now manufactured and sold byCorelle Brands.[5]
Corelle is best known for its three-layered glass. Nevertheless the Corelle product line includes items of other materials, such as stoneware and plastic.
Vitrelle is the brand name specific to the three-layered glass material. The outer layers are clear glass, while the inner layer is opaque white. For those items with colored decoration, the decoration is a glassy ink applied on the outside of the three-layered item. The resulting tableware is strong and lightweight.[4]
Corelle dishware has come in many different patterns over the years since it was introduced, but most of these were retired when Corning divested itself of theCorning Consumer Products Company. Many of the patterns were also used inCorningWare cookware. Retired patterns are still widely available.[6]
