What is Borosilicate Glass?

Most people don’t realize is that not all glass is created equally. Borosilicate glass is a special kind of glass that incorporates two chemicals in high concentration: boron trioxide and silica. These safe and environmentally-friendly chemicals make borosilicate glass more heat resistant than other forms of glass on the market. Borosilicate glass is completely non-toxic and highly durable. Borosilicate glass does not crack at high temperatures found in ovens. It’s ideal, therefore, for casserole dishes.
