The linear expansion coefficient of a glass teapot

The linear expansion coefficient of a glass teapot is 3.3×10-6/K.
High borosilicate glass (also known as hard glass), because the coefficient of linear thermal expansion is (3.3±0.1) ×10-6/K, it is also called borosilicate glass 3.3. It is a kind of glass material with low expansion rate, high temperature resistance, high strength, high hardness, high transmittance and high chemical stability. Because of its excellent performance, it is widely used in solar energy, chemical industry, pharmaceutical packaging, electric light source, process jewelry and other industries
