Instruction of borosilicate glass:

1.Borosilicate glasses are most well known for having very low coefficient of thermal expansion, making them resistant to thermal shock, more so than any other common glass.

2.Borosilicate glass is sometimes used for high-quality beverage glassware. Borosilicate glass lends the kitchenware and glassware increased durability along with microwave and dishwasher compatibility.

3.Borosilicate glass has higher percentage of light transmittance than ordinary glass.

4.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.

5.In addition to the quartz, sodium carbonate, and calcium carbonate traditionally used in glassmaking, boron is used in the manufacture of borosilicate glass. Typically, the resulting glass composition is about 70% silica, 10% boron oxide, 8% sodium oxide, 8% potassium oxide, and 1% calcium oxide (lime). Though somewhat more difficult to make than traditional glass (Corning conducted a major revamp of their operations to make it), it is economical to produce because its superior durability, chemical and heat resistance finds excellent use in chemical laboratory equipment, cookware, lighting, and in certain cases, windows.

6.Borosilicate glass begins to soften around 821°C (1510°F); at this temperature, the viscosity of type 7740 Pyrex is 107.6 poise. Borosilicate glass is less dense than ordinary glass.
