Burnout

The molds are set in a kiln to burn out the wax. We say burn-out , not a melt-out because the kiln gets crazy hot, as you’ll see. This guarantees all the wax is gone from the mold – which is important because were any left behind when the bronze was poured in, it would cause something like a small explosion. Also, the extreme heat “fires” the mold into a harder substance better able to support the heat and weight of the bronze. (Pictures by Howard)

This kiln is made from an old electric clay kiln which Howard refitted to run gas and expanded a bit with extra firebricks. Most of his gear is home built of the highest design and workmanship.
