What is Borosilicate Glass?
A type of glass containing boron trioxide that is highly resistant to thermal shock, making it ideal for cookware that transitions between extreme temperatures.
Borosilicate glass is a specialized type of glass that contains at least 5% boron trioxide, giving it exceptional resistance to thermal shock — the stress caused by rapid temperature changes. Unlike regular soda-lime glass, borosilicate glass can safely go from freezer to oven without cracking. This makes it the gold standard for laboratory glassware, premium cookware, and food storage containers. The TEVOLUX air fryer uses thick, tempered borosilicate glass bowls that can withstand the high temperatures of air frying (up to 400°F) and then be placed directly in the freezer or microwave. Borosilicate glass is also non-porous, meaning it will not absorb food odors, flavors, or stains over time — unlike plastic or ceramic-coated alternatives.
