We all use glass. Even if you drink out of plastic cups and never look in a mirror, there's a very good chance you have glass windows in your home. If you own a vehicle, it has glass windows, too. The world would be a very different place without glass — and not in a good way! If you haven't spent a lot of time thinking about glass before, then you have come to the right place. This website is a place where we publish articles about glass, glass blowing, various building materials made from glass, and so much more.
