High temperatures 1500 to 1800 degrees Fahrenheit and pressure force the wax from the shell and the wax melts out, thus becoming "lost". If the sculpture is large or complex, it will usually have to be divided into smaller pieces, with each piece needing its own individual mold.
Pewter, an alloy of nickel and silver, is another less-costly alternative. The artist then gives the surface a smooth reflective shine by polishing it with a cloth dusted with light abrasives.
Gorgeous, yes! Thank you for your intercession, Judith.
The main work starts only now. Break Out Once the bronze and ceramic shell has cooled, the ceramic shell is broken off to separate the bronze metal from the shell.

The client can also provide photos to give the bronze sculpture artists an idea of what he or she wants. Next, he sharpens details in the face, hair, and finger and toenails using small, specially shaped iron tools.
The workers must wear protective face shields, clothing, gloves, and boots. An armature is usually necessary when portraying a figure in motion or in a standing posture. Once again, bubbles may need filling, and surface details and structures may have to be rebuilt wherever pieces are joined.

STEP 2: After the bronze has cooled and solidified, the mold is broken open, discarded, and the casting--the final "positive"--is removed. He uses hot metal tools as well as his hands. Here, a dramatic mane has been added, and texture on the face has been smoothed. The "lost-wax" process explained above is primarily used for casting sculptures in bronze.
