How is glass made?

Question asked by: knowitall

Glass is composed of silica, from sand, and soda and lime.

It can be created naturally in small amounts - for instance if those constituents happened to be present then a lightning strike could result in the creation of glass!

Man made glass will tend to have other chemicals added to make it clear or coloured.

We now rely on glass everywhere where we want to see out but protect ourselves from the elements, with the exception of the use of plastic instead in a few places.

Thus your windows in your home are almost certainly glass.
