Question

The constituents of soft glass?

Answer 1

• Glass is an inorganic solid material that is usually transparent or translucent that is used in numerous applications in our daily lives.
• There are generally two types of glasses, one such type is soft glass and the other is hard glass.
• Soft glass is generally known as soda-lime glass and hard glass is generally referred to as borosilicate glass.
• The soft glass is made up of soda also known as sodium carbonate (${\mathrm{Na}}_2{\mathrm{CO}}_3$), silica (silicon dioxide ${\mathrm{SiO}}_2$), and lime (calcium oxide $\mathrm{CaO}$), and their chemical composition is as follows-
• Sodium carbonate (${\mathrm{Na}}_2{\mathrm{CO}}_3$) - 15%
• Silicon dioxide( ${\mathrm{SiO}}_2$) - 70%
• Calcium oxide( $\mathrm{CaO}$) -9%
• The general formula for soft glass is- ${\mathrm{Na}}_2\mathrm{O}.\mathrm{CaO}.6{\mathrm{SiO}}_2$
