Obviously, with this term we do not refer exclusively to the specific group of modern "fusion and soldering" techniques whereby, through the application of high temperatures (obtained with an oxyacetylene welding torch, various kinds of burners, electric arc, etc.), two metal pieces sometimes of different nature are "welded" together, but to the whole set of "assembling" techniques used to join the different components of an artwork. Welding is a widely used technique in contemporary sculpture, although examples can be seen in the most ancient statuary. The bronze casting technique offered undeniable advantages over stone carving, as the greater cohesion of the material allowed the artist to explore more freely the expressive possibilities of posture and pose of its subject into space, without risking any damage and thus achieving a more lifelike and natural result.

With the Renaissance, and the general rediscovery of the culture of classical antiquity, the technique was revived. Site specific art is in fact a permanent installation. Bronze casting of small-sized objects was still employed, but these were "solid" castings, unfeasible on a larger scale. The technique fell into disuse during the Middle Ages, surviving only in the Byzantine Empire. Among the best-preserved ancient pieces produced with this method are the Riace Bronzes (Bronzi di Riace), dating back to the Classical period. � The dry stage: The plaster no longer contains moisture and it is at maximum strength.The lost-wax technique, for casting large, hollow bronze statues, has been known since ancient times. Tools get clogged and require cleaning quite often.

The mixture hardens substantially and metal tools are required for its manipulation. a small scale model or rough draft of an unfinished sculpture.

The plaster is very fragile at this stage. The plaster becomes brittle and it can be cut with a knife or dug into with a spoon. � The rigid stage: Occurs once the mixture begins to set. Plaster can be applied with a putty knife or spatula, and it can be modeled like clay. � The putty stage: The plaster thickens to the consistency of toothpaste. PLASTER STAGES � The liquid stage: This stage occurs immediately after mixing with water.
