Question

Write a note on the manufacturing of glass.

Answer 1

1. Glass is prepared by heating (SiO) silicon-di-oxide until it melts, about 1700°C, and Sodium Carbonate is added to it.
2. Then it cooled down really fast.
3. When SiO2 silicon-di-oxide melts, the silicon and oxygen atoms break out of their crystal structure.
4. If we cooled it slowly, the atoms would slowly line up back into their crystalline arrangement.
5. But if we cool the liquid fast enough, the atoms of the silica will be halted in their tracks, they won’t have time to line up, and they will be stuck in any old arrangement, with no order to the arrangement of the atoms.
6. We call materials like this amorphous.
