Glass
Glass is made of silica and contains silicon oxide.
 
Type of glass
 

 
Glass and composition Characteristics

Fused silica glass

  • Silica
  • Resistant to heat
  • Chemically inert

Soda-lime glass

  • Silica
  • Calcium carbonate
  • Sodium carbonate
  • Low melting point
  • Easy to shape

Borosilicate glass

  • Silica
  • Boron oxide
  • Sodium oxide
  • Aluminium oxide
  • High resistance to heat and chemicals compared to soda-limed glass

Lead crystal glass

  • Silica
  • Lead(II) oxide
  • Sodium oxide
  • Low melting point
  • High refractive index
 
Application of glass
Application Explanation
Laboratory apparatus
  • Made of borosilicate glass
  • High resistance to heat and chemicals
Bulb
  • Made of soda-lime glass
  • Resistance to heat 
  • Easily to shape
