Casting Bronze Sculpture
The "Lost Wax Process".

6. Pouring the Bronze

The bronze ingots are melted (2100 degree F) in a crucible which is sitting in a special furnace. The cylinders or Ceramic shells are buried in a san pit to hold them upright, and protect everyone from bronze, should the cylinders or ceramic shell give way when bronze is poured into the hollow cavity of the cylinder. Melted bronze is then poured into the hollow cavity within the shell.

7. Revealing the Bronze

Once the bronze is cool, the shell is broken away with hammer and chisel. Bars and the funnel are also removed at this time.

8. Sandblasting

Any remaining shell is removed by two stages of sand-blasting; first with coarse, then with fine sand.
