Sculpture is a type of visual art that operates in three dimensions. The word sculpture comes from the Latin word sculpere, which means to carve. Sculptors use a variety of materials to create their sculptures. While many traditional materials include wood, stone, metal, and ceramics, other sculptors specialize in non-traditional materials. They use materials such as ice, toothpicks, and even LEGO. Sculptors also use materials, colors, texture, and size to evoke an emotion or response from the viewer. Their methods vary, too. Sculptors use one of four primary methods to make their sculptures. These methods include carving, molding, casting, and assembling.
