Borosilicate glass includes boron trioxide, which has a low coefficient of thermal expansion. This implies that, unlike conventional glass, it will not crack when exposed to high-temperature changes. For high-end restaurants, laboratories, and vineyards, its durability has made it the glass of choice. Borosilicate glass contains about 15% boron trioxide, which is the magical component that modifies the behavior of glass and makes it resistant to thermal shock. The "Coefficient of Thermal Expansion," or the rate at which the glass expands when exposed to heat, is used to determine how resistant the glass is too extreme temperature fluctuations. As a result, borosilicate glass can go straight from the freezer to the oven rack without splitting. This implies that you may pour boiling hot water into borosilicate glass to steep tea or coffee without worrying about the glass fracturing or cracking.
