Borosilicate is a type of glass that contains silica and boron trioxide. This unique composition gives it a low thermal expansion coefficient, making it resistant to thermal shock. As a result, borosilicate glass is commonly used in laboratory glassware, cookware, and other applications where durability and heat resistance are essential. One of the most well-known brands of borosilicate glass is Pyrex, which is popular for its kitchenware. Additionally, borosilicate glass is often used in scientific instruments and optical devices due to its clarity and strength. Its versatility makes it a preferred choice in various industries.
