Set of Two Glasses

Bodum's double-walled insulated glassware is made from durable Borosilicate glass.

Dishwasher & microwave safe.

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. Borosilicate glass substitutes boron oxide in place of the soda and lime used in traditional glassware. The boron oxide acts as a glue holding the silicate together, and due to the small size of boron particles, the glass is held together tighter, resulting in a stronger end result.

Borosilicate glass doesn't need to be as thick as traditional glass to be just as strong. Borosilicate is simply a different type of glass that is resistant to temperature swings and scratching. Because the particles are held together so tightly, borosilicate glass is dishwasher safe and will not become cloudy over time. After 100 cycles, the glass will be as clear as the day you bought it. Treat with care as you would any glass product.
