What happens when sand is heated?

Answer 1

It gets hot.

If it gets hot enough then the molecular, crystalline bonds deform and it becomes a gelatinous mass of hot goo. When this goo cools down slowly, the bonds reform and will (depending on the cooling time) form into crystalline structures (which, while still in semi-fluidic form, can be moulded into all sorts of shapes) to form common glass (whose colour and rigidity depend upon impurities).

Conclusion : BUT! who really cares!?

Answer 2

If it's heated hot enough, it makes glass. Other than that, it just gets hot.

Basically, the sand gets so hot that it melts (in a sense) together and then, when cooled rapidly, it doesn't have time to form a crystal lattice (grains of sand), so it stays melted together.

Answer 3

Sort of. When sand is heated to 1700 degrees Fahrenheit, it liquifies. When cooled, it turns glassy.

But to get something that looks more like our everyday glass, there has to be a more controlled process. Some chemicals are needed to clear the melt, and cooling has to be carefully controlled to avoid cracking.

Answer 4

nothing... its like trying to burn a rock...

Answer 5

If you heat the water long enough, it will evaporate and only the sand will be left.

Answer 6

It melts and becomes glass.

Answer 7

Sand does not burn.

Answer 8

It Turns to Glass ya Dope

Answer 9

Most people have misinterpreted your question--I believe that they think you mean does sand spontaneously combust, but I believe that you mean what happens when you turn sand up to very high temperatures. In this case, it turns into a glasslike substance (you should just use a Wikipedia article on burning or sand--at least it is written and corrected by 5-20 people over many weeks or even months who have time to do research and consider the topic intensely and not just written by one person in 3 minutes).
