Can glass be turned back into sand?

Question

Just Wondering... :)

Answer 1

Well technically yes although you wouldn't think of it as the 'sand' you're referring to. The term sand is actually a classification of grain size. It is defined as granular material with grains between 1/16th and 2 mm in size. The sand we typically see on say beaches is grains of silica (quartz) with other minor minerals like feldspar. It's called sand because the grains are between 1/16th and 2 mm in size. If the grains were smaller it would be called silt or clay. So you could turn glass back into sand simply by crushing it so the resulting grain sizes were in the proper size range. It wouldn't look like beach sand though because once silica is melted to become glass it loses it's crystalline structure (becomes amorphous).

They actually mix a couple of other ingredients with the sand to make glass: soda ash and limestone. The melting temperature is around 1400 to 1600 degrees centigrade. Without adding the soda ash and limestone, sand by itself would need a temperature of about 1850 °C, or 3360 °F to melt! A ceramic kiln can melt some things at those temperature ranges.

Answer 4

Glass is artificial compound not found in nature. So it can be broken down in terms of size so that it will be the same as grains of sand that come from rocks.

But it is not the same formula as sand that is usually mostly quartz.

Answer 6

yes. all you have to do is ground it up fine enough. This is also a trick that glass-eaters employ (I used to know one in the carnival!).

Answer 7

I don't think so but who nows.
