How Do You Turn Sand into Glass?

Imagine you're playing with a bag of tiny white beads, that's like sand. If you put them in an oven and heat them up to around 2,000 degrees, they melt into something clear and smooth, just like glass! It’s like turning sugar crystals into syrup with enough heat.

Sand is mostly made of a mineral called silica, which turns into glass when it melts. The more heat you apply, the smoother the glass becomes. People have been doing this for thousands of years, even ancient Egyptians used it to make shiny jewelry and mirrors.
