The origin and function of quartz
2 years ago
592
These react together to form silicon dioxide,whose molecules arrange themselves into a regular crystalline form known as quartz.Quartz is commonly found in sand,where it often makes up most of the grains and is the main ingredient in most type of glass.Of course, you probably noticed that glass isn't made of multiple tiny bits of quartz,and for good reason.For one thing, the edges of the rigidly formed grains and smaller defects within the crystal structure reflect and disperse light that hits them.But when the quartz is heated high enough the extra energy makes the molecules vibrate until they break the bonds holding them togetherand become a flowing liquid,the same way that ice melts into water.
