Borosilicate glass is a strong heat-resistant glass traditionally used to make scientific lab glass. Borosilicate glass doesn't need to be as thick as traditional glass to be just as strong due to the bonding capability boron oxide. Borosilicate is simply a different type of glass that is resistant to temperature swings and scratching. In addition to being dishwasher safe borosilicate will not become cloudy over time; you can rest assured that after 1,000 cycles, the glass will be as clear as the day you bought it.

Bely recommends using care when placing ice into the glass to avoid fracturing the inner layer. Do not use metal spoons or place the glass into a crowded dishwasher.
