Today much sculpture is made for intermittent display in galleries and museums, and the ability to transport and store the increasingly large works is a factor in their construction.
Small decorative figurines, most often in ceramics, are as popular today (though strangely neglected by modern and Contemporary art) as they were in the Rococo, or in ancient Greece when Tanagra figurines were a major industry, or in East Asian and Pre-Columbian art.
Sculpture is the branch of the visual arts that operates in three dimensions. Durable sculptural processes originally used carving (the removal of material) and modelling (the addition of material, as clay), in stone, metal, ceramics, wood and other materials but, since Modernism, there has been an almost complete freedom of materials and process.
A wide variety of materials may be worked by removal such as carving, assembled by welding or modelling, or molded, or cast.
A basic distinction is between sculpture in the round, free-standing sculpture, such as statues, not attached (except possibly at the base) to any other surface, and the various types of relief, which are at least partly attached to a background surface.
