Usage
Borosilicate glass's refractory properties and physical strength make it ideal for use in laboratories, where it is used to make high-durability glass lab equipment, such as beakers and test tubes. In addition, borosilicate glass warps minimally when exposed to heat allowing a borosilicate container to provide accurate measurements of volume over time.
During the MID-twentieth century borosilicate glass tubing was used to pipe coolants (often distilled water) through high power vacuum tubebased electronic equipment, such as commercial broadcast transmitters.
Glass cookware is another common usage; A borosilicate glass pie plate is almost the American standard pie dish. Borosilicate glass measuring cups, featuring painted-on markings illustrating graduated measurements, are also widely used in American kitchens.
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.
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.
Borosilicate glass can handle both extreme heat and cold, making it very popular for laboratory glassware and other scientific instruments. It also has a reduced rate of thermal expansion, which can make it useful for things like telescopes and other high precision lenses where the surface of the lens must be very even to get a clear image.
The glass is also resistant to chemical corrosion, which can be extremely useful for experiments and chemical storage. Although all glass tends to be fairly chemical resistant, this variety is able to handle extremely volatile chemicals, along with nuclear waste.
In addition to being found in scientific labs, borosilicate glass can also be seen in windows, high-end lighting, cookware, and some other applications. As a general rule, products made with it will be more expensive than those made with ordinary glass, because these products require greater heat and more labor to produce.
