Glass

Glass has widespread practical, technological, and decorative use from window panes and tableware to optics. Traditionally, glass has been used to make vessels, such as bowls, vases, bottles, jars, and drinking glasses, since it can be formed into any shape. Paperweights and marbles have also been made from it in its most solid forms. It is possible to color glass by adding metal salts or to paint and print it as enameled glass.
