Bodum's insulated glassware is made from durable Borosilicate glass. Borosilicate glass is a strong heat-resistant glass that weighs less than traditional glassware. Used to make scientific lab glass, borosilicate glass (medical grade glass) is stronger than traditional "soda-lime" glass and can be used for everything from drinkware to cookware.
