How Is Sand Turned into Glass?

Answer

Sand is turned into glass by super heating the sand. Sand must be heated to about 1700 degrees Celsius in order for it to become hot enough to melt and become liquid. The liquid sand is then cooled and becomes glass. Sand usually stays in a state that is somewhat between a liquid and a solid and is more easily manipulated in that state. In commercial glass making, sand and other items like calcium carbonate and sodium carbonate are mixed together to create glass.
