Glass

Look around you. All the things that we build, that we travel in, that we use in our homes, schools, and workplaces... just about everything is made from materials that we either dig out of the ground or get from the plants growing there. This colorful and informative book introduces young readers to one of these important materials -- glass. It explains what glass is, how it is formed, and how it is used to make bottles, jars, windows, mirrors, and lenses. It shows clearly just how important glass is to the world we live in. Book jacket.
