Busycon Canalacalatum (aluminum, 1992) is a large, free-standing biomorphic abstract sculpture. BC was based initially on a fragment of a whelk seashell, for which it is named. Another source of inspiration for this sculpture was the beautiful form of the female figure, specifically the lower torso and legs. The original pattern was modeled full-size in plastilene, an oil-based clay, over a steel armature. Plaster molds were made from the finished clay, then a wax cast was made from the molds. The wax was sectioned, gated, and coated with a refractory mold material called ceramic shell. The finished shells were then fired in a large kiln at 1600 F, at which point the wax drains out (the "lost-wax" process). Aluminum ingots were melted in an electric induction furnace to a temperature of 1300 F, and poured into the shells. After cooling the ceramic shell was broken away to reveal the rough castings. These were joined via TIG welding, and the seams were "chased" to refine the form. The cylindrical aluminum base was fabricated and welded to the cast form. Black paint was applied to the base and sculpture interior to provide contrast. The process is both costly and labor-intensive, but the results make it all worthwhile.
