The glass may be broadly classified as:
1. Soda-lime glass
2. Potash lime glass
3. Potash lead glass
4. Common glass and
5. Special glasses.

1. Soda Lime Glass: It is mainly a mixture of sodium silicate and calcium silicate. It's fusible at low temperature. In the fusion condition it can be blown or welded easily. It's colourless. It is used as window panes and to the laboratory tubes and apparatus.

2. Potash Lime Glass: It is mainly a mixture of potassium silicate and calcium silicate. It is usually known as hard glass. It fuses at high temperature. It is used in the actual manufacture of glass articles which may have to with stand high conditions.

3. Potash Lead Glass: It is mainly a mixture of potassium silicate and lead silicate. That possesses bright lustre and good refractive power. It is utilized in the manufacture of artificial gems, electric bulbs, lenses, prisms and many others.

4. Common Glass: It is mainly a mixture of sodium silicate, calcium silicate and also iron silicate. It is brownish, green or yellow in color. It is mainly used within the manufacture of medicine bottles.

5. Exclusive Glasses: Properties of glasses might be suitably altered by changing standard ingradients and adding few additional ingradients. It has now emerged as versatile material to meet up with many special requirement in anatomist. The following is the list of many of the special glasses.

(a) Fibre glass
(b) Foam glass
(c) Bullet proof glass
(d) Structural glass
(e) Glass black
