the constituents of hard glass is potassium carbonate , limestone and silica
The type of glass used in laboratories is BOROSILICATE it is a heat resistant glass. It's main constituents are silica, which is used in normal glass, and boron.
Diamond is hardest Diamond cuts glass Glass does not cut diamond
The Macbook is hard. It is made of polycarbonate glass and plastic. The screen is glass too.
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 more resistant to thermal shock than any other common glass.
soft glass Hard glass crown glass flint glass glass ceramics etc
Glass is about 6-6.5
it is Orthoclase
Glass is easy to break and steel is hard
soft because it will absorb the impact more than hard glass
a hard glass test tube is a test tube made out of glass that is almost impossible to break.
The two main constituents of glass are : Silicon Dioxide , Sodium Carbonate. Alumina or borosilicate are added depending on the nature of the glass required. Glass is a 'supercooled' liquid. , that is a liquid below its natural freezing point. Supercooled liquids do not have a crystalline structure, which pure solids have. However, glass if left for long periods of time (hundreds of years) may start to 'cloud', this is the crystals forming from the supercooled liquid.
