Question

Match the following classification of glasses with their specific uses:

a.	Soda lime glass	1.	Used in the manufacturing of glass articles which have to withstand high temperatures.
b.	Potash lime glass	2.	Used in the manufacturing of artificial gems, electric bulbs, lenses, Prisms, etc.
c.	Potash lead glass	3.	Used in the manufacturing of glass tubes, laboratory apparatus, plate glass, window panels, etc.
d.	Common glass	4.	Used in the manufacturing of medicine bottles

1. a - 1, b - 3, c - 2, d - 4
2. a - 3, b - 1, c - 2, d - 4
3. a - 3, b - 1, c - 4, d - 2
4. a - 1, b - 3, c - 4, d - 2

Answer 1

Correct Answer - Option 2 : a - 3, b - 1, c - 2, d - 4

Concept:

Different types of glasses, their constituents, and applications are as follows:

Type	Constituents	Applications
Potash lead glass (Flint glass)	Fusion of Silica, Potash, and Lead	Cut glass Electric glasses and lenses Prisms
Soda-lime glass (Soda ash glass/ Window glass)	Fusion of Silica, Lime, Soda, and Alumina	Doors Windows
Bottle glass (Common glass)	Sodium silicate, Calcium silicate, and Iron silicate	Household bottles Medicine bottles
Potash lime glass (hard glass)	Silicates of potassium and calcium	Used in the manufacturing of glass articles that have to withstand high temperatures Also used for Hollow equipment for laboratory
Optical glass	Phosphorus, lead silicate	Lenses
Borosilicate bottles (Pyrex glass)	Fusion of Silica, Borax, Lime, and Feldspar	Laboratory equipment

Hence, Option b is the correct match.
