Borosilicate glass - Wikipedia, the free encyclopedia (396 words) |
 | In addition to the quartz, sodium carbonate, and calcium carbonate traditionally used in glassmaking, boron is used in the manufacture of borosilicate glass. |
| Borosilicate glass has a very low thermal expansion coefficient, making it a popular material for objects like telescope mirrors, where it is essential to have very little deviation in shape. |
| Borosilicate glass is sometimes used for high-quality beverage glassware; Bodum, Inc. markets a line of French coffee presses and double-walled beverage glasses made of borosilicate, lending them increased durability and microwave/dishwasher compatibility. |
