Unlike regular glass, which is composed of silicon dioxide, sodium oxide and calcium oxide, or – to put it simply – silica, soda and lime, the borosilicate glass composition also includes at least 5% boric oxide. This special ingredient produces borosilicate glass, or “boro”, as it is often called, notable for its high tolerance to heat and extreme resistance to severe temperature changes.
