First Bronze Pouring of "Ascension"

Today was the first pouring of bronze for "Ascension"!  The shells had been built up over the hollow wax sections over a period of time. The shells were then placed into the furnace and the wax was melted out - a process referred to as "lost wax".

Next they took special buckets and collected the molten bronze and poured the liquid metal into the now-hollow ceramic shells. Once the bronze cools, they break apart the ceramic shells using hammer and pneumatic tools. After removing the hard shells, the sprues are then cut off using plasma torches.

Once that is completed, the sections of bronze are cleaned up by sand-blasting the last bits of plaster shell residue.

Finally, after the pieces are cleaned up they are ready to be welded back together.

Tomorrow I'll post photos of the sculpt being metal-chased.
