Glass blowers have been creating art out of raw materials for a long time. The student cased glass lamp shades we offer are one example of the careful craftsmanship of skilled glass blowers. While many novices to antique lighting would falsely assume these glass covers had been painted to achieve a certain color, the reality is that most of these covers are two different layers of glass. Since the days of the Victorian era, cased glass lamp shades have been created by combining two layers of glass in molten form on top of each other using a tool known as a pontil. Once the glass is forcibly blown into a mold, it hardens into the popular shades that have made many antique lamps and lighting fixtures into home-front favorites.
