02. The defination of borosilicate glass

Borosilicate glass is a type of glass that includes at least 5% boric oxide. The boric oxide makes the glass resistant to extreme temperatures, and also improves its resistance to chemical corrosion. This glass is very popular in the manufacture of scientific instruments, and it was once widely used to make glass for kitchens as well. Today, soda-lime glass is the glass of choice for kitchenware, due to the fact that it is generally cheaper to produce.

Invention of borosilicate glass is generally credited to Otto Schott, a German glassmaker who worked in the 19th century. By the late 1800s, the process for making it had been refined, and in 1915, a famous line of borosilicate kitchen products was released under the Pyrex label. Because it is stronger and more durable than conventional glass, it has a number of far reaching uses.

This glass is not invincible, of course. It will crack if subjected to very sudden and radical temperature fluctuations, or if it is dropped. The glass is more likely to crack or snap than to shatter, however, making it safer to have around in a situation where breakage is a concern. In the event that products made with the glass do crack, it is generally easier and safer to clean up than shattered glass.
