How is Glass Made?

Inquiring minds need to know:  how is glass made?  Click on this link for a video explaining the process.  Glass is actually made from liquid sand. You can make glass by heating ordinary sand (which is mostly made of silicon dioxide) until it melts and turns into a liquid. When the molten sand is allowed to cool, it doesn’t return back to its gritty yellow state that you began with—the heating causes it to undergo a complete chemical transformation, thus attaining a new inner structure. Regardless of the technique employed for cooling the molten sand, it never quite sets into a quintessential solid. Instead, it turns into a frozen liquid or—what a material science graduate would like to call—an amorphous solid. Basically, glass is more like a cross between a solid and a liquid, featuring some crystalline structures generally found in solids, as well as some molecular randomness often seen in liquids.

Now you know!
