Preparing and Loading the Charcoal Kiln

The first fire is relatively small and is intended to dry out some of the moisture in the clay/earth around the kiln remaining after construction and before winter. After cooling and cleaning it out, a “floor” is created above the steel floor slats using thin boards and brown charcoal from previous charcoal runs. Then the wood (mostly Pine) is split and stacked vertically from back to front leaving only a small airspace at the top. The front will be filled with kindling and bark and then the opening closed up and mostly sealed before lighting. Controlling the air intake slows down the burn and prevents loss/crumbling/cracking of charcoal wood. read more about the kiln and making charcoal.

Installing the Higuchi (tuyere)

Installing/repairing the higuchi (tuyere), the point where the air enters the forge and temperatures are very high. In this case the fire clay to form the tuyere and fit it to the brick construction Japanese swordsmith forge is a traditional brasque recipe consisting of 6:2 charcoal powder/fines to natural clay, mixed with just enough water to stick together well. The forge must be allowed to dry fully before lighting or steam will crack the clay. see more of the island forge kajiba project
