The thermally bonded layers give Corelle its strength, allowing it to be much thinner than other dinnerware. Introduced by Corning Glass Works in 1970, it is now manufactured and sold by World Kitchen. Corelle is chemical resistant, durable, and lightweight: A typical Corelle dinner plate measuring 26 centimetres across weighs 355 grams.Corelle has had hundreds of patterns over the years since it was first introduced. Most of these patterns were retired once this brand name was purchased by World Kitchen. Many of the Corelle patterns also were used in CorningWare cookware. Many of the retired patterns are still in demand even though they are necessarily used items being resold due to this demand. The most popular of these retired patterns are Blue Heather, Butterfly Gold, Colonial Mist, Indian Summer, Meadow and Spring Blossom Green (Crazy Daises).
