Glass art refers to individual works of art that are substantially or wholly made of glass. It ranges in size from monumental works and installation pieces, to wall hangings and windows, to works of art made in studios and factories, including glass jewelry and tableware.
The first uses of glass were in beads and other small pieces of jewelry and decoration. Beads and jewelry are still among the most common uses of glass in art, and can be worked without a furnace.
It later became fashionable to wear functional jewelry with glass elements, such as pocketwatches and monocles.
