Answer 2

Answer:

True

Explanation:

Glass is a solid-like and transparent material which is used in many applications in our daily lives. Glass is made from natural and abundant raw materials (sand, soda ash and limestone) that are melted at very high temperature to form a new material which is called as glass. At high temperature glass is structurally similar to liquids, however at ambient temperature it behaves like solids. As a result, glass can be poured, blown, press and moulded into plenty of shapes.

Glass melting requires raw materials which are of two kinds: different types of sand and recycled glass. These raw materials are mixed together, charged in a furnace where there are melted at around 1500°C to form molten glass. The molten glass is then taken out of the furnace to be shaped and cooled down afterwards. For many applications the glass obtained may be further processed to have specific properties such as increased mechanic strength and higher resistance to breakage.

Therefore, the above statement is true that "glass is made of sand".
