Answer 1

Glass is an inorganic solid material that is usually transparent or translucent in nature. The glass is usually made up of sand, the common form of silica is easily available in nature. The chief component of glass is silicon dioxide (${\mathrm{SiO}}_2$). There are many types of glasses in which there are four main types-

• Annealed Glass
• Heat Strengthened Glass
• Toughened Glass
• Laminated Glass
• Pyrex glass

Pyrex glass is the type of glass that is used for making glass apparatus and cooking utensils. It is created by combining barium silicate( ${\mathrm{Ba}}_2{\mathrm{O}}_4\mathrm{Si}$) with sodium silicate(${\mathrm{Na}}_2\mathrm{O}{\left({\mathrm{SiO}}_2\right)}_{\mathrm{x}}.{\mathrm{xH}}_2\mathrm{O}$)
