Corelle is a brand of glassware and dishware. It is made of Vitrelle, a tempered glass product consisting of two types of glass laminated into three layers. There's nothing else like Corelle. The secret is our proprietary three-layer glass—yes, glass--fired to an amazingly strong and lustrous finish, backed by our No Chip, No Crack Guarantee. Corelle dinnerware comes in styles for every taste, mood and season, and you can mix and match them to make them your own. Is Corelle made in America? Is Corelle made of bone china?
