What is one primary use of glass in sculpture?

One primary use of glass in sculpture is that it can be cast in molds or sculpted by hand. This versatility allows artists to create complex forms and detailed textures, transforming a traditionally fragile material into a medium for intricate and durable artistic expressions. When glass is heated to a malleable state, it can be formed into various shapes through casting in molds, which is ideal for replicating precise designs. Additionally, glass can be sculpted by hand, enabling artists to manipulate the material to achieve their desired artistic vision. This method broadens the scope of creativity in glass sculpture, as it accommodates both large-scale works and detailed small pieces, making it a favored material for sculptors looking to explore innovation in their art.
