Borosilicate glass is different from soda-lime glass because it:

Borosilicate glass is distinguished from soda-lime glass primarily by its melting point. It is formulated to withstand higher temperatures, which makes it ideal for applications that require thermal stability, such as laboratory glassware and cookware. This higher melting temperature is due to the specific composition of borosilicate glass, which includes silica and boron trioxide, providing it with enhanced durability and resistance to thermal shock.

In contrast, soda-lime glass, which is the most common type of glass, is made primarily from silica, soda, and lime. This composition leads to a lower melting point compared to borosilicate glass. The increased temperature resistance of borosilicate glass allows it to be used in environments where high heat is present, something that soda-lime glass would not handle effectively.
