Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion, making them resistant to thermal shock (which the main cause for cracks in glass besides physical knocks), more so than any other common glass. Though more difficult to make than traditional glass due to the high melting temperature required, it is economical to produce. Its superior durability, chemical and heat resistance finds use in chemical laboratory equipment, cookware, lighting, and in certain kinds of windows.


Borosilicate glass was first developed by the German glassmaker Otto Schott in the late 19th century. In 1915 the Pyrex kitchen ware was introduced using Borosilicate glass, the name became a synonym for borosilicate glass in the English-speaking world. However, borosilicate glass is the name of a glass family with various members tailored to completely different purposes.

Physical characteristics:

The temperature differential that borosilicate glass can withstand before fracturing is about 165 °C (329 °F). This compares well with soda lime glass, which can withstand only a 37 °C (99 °F) change in temperature and is why typical kitchenware made from traditional soda-lime glass will shatter if a vessel containing boiling water is placed on ice, but Pyrex or other borosilicate laboratory glass will not


Health and science - virtually all modern laboratory glassware is made of borosilicate glass. It is widely used in this application due to its chemical and thermal resistance and good optical clarity. Electronics - borosilicate glasses also have an application in the semiconductor industry in the development of microelectromechanical systems (MEMS). Cookware - glass cookware is another common usage Borosilicate glass is sometimes used for high-quality beverage glassware as well. The Borosilicate glass is thin and durable, microwave- and dishwasher-safe. Lighting & many light fixtures - many high-quality flashlights & light fixtures use borosilicate glass for the lens. This increases light transmittance through the lens compared to plastics and lower-quality glass. Optics - most astronomical reflecting telescope use glass mirror components made of borosilicate glass because of its low coefficient of thermal expansion. In addition - aquarium heaters are sometimes made of borosilicate glass and interesting also is the fact that The thermal insulation tiles on the Space Shuttle were coated with a borosilicate glass.

And on a personal note ...

We love using the borosilicate glass material in our products for all the reasons mentioned above, the borosolicate glass is of-course an integral part of our Bell Jar table lamp collection and more!
