Glass art has been produced for several millennia. Glass was originally used for food storage, but artists found it an interesting medium for their expression. The ancient Roman artists made beautiful multi-colored wine glasses for their patrons. Modern artists create sculptures in many different forms from art. These pieces are often sold at fairs dedicated to displaying glass. They take this unique art and give it a platform of its own. This allows collectors an opportunity to see and find older pieces they are interested in, and it gives modern artists a showcase for their most recent work.
