Cut glass refers to glassware that has been shaped and decorated by cutting into the surface with a sharp tool. This technique creates intricate patterns and designs, enhancing the glass's aesthetic appeal. Cut glass is often used for decorative items, such as vases and bowls, as well as functional pieces like drinking glasses. The process of making cut glass dates back to the 16th century and became particularly popular in the 19th century with the rise of Bohemian glass and American Brilliant Cut Glass. Artisans use various techniques, including wheel cutting and acid etching, to achieve different textures and effects on the glass surface.
