You use glass from morning to night every day, from the mirror you look in when you wash your face in the morning to the bulbs that light up your home after dark. All sorts of foods and drinks are stored in glass bottles and jars. Many of your electronic gadgets have glass screens. Cameras and spectacles, or eyeglasses, have glass lenses. The signals that carry your phone calls and texts, and Web pages when youre online, make part of their journey along glass communications cables. And every home, school and workplace has glass windows. You wouldnt want to live without glass.
