Glass is probably the most overlooked material in history. It is essential to our lives, even more important than plastic. To me, a world without glass is even harder to imagine than a terraforming Mars (which most scientists agree is practically impossible). Without this miracle all around us, you wouldn't be able to use a touch-screen phone, turn on a glass light, see from a window, wear glasses, or enjoy a drink from a glass bottle on your bedside table. You won't be able to receive email, phone calls or access the Internet.
