Building a Traditional Charcoal Making Kiln
As part of the island kajiba project, reclaimed and natural materials were used to construct a larger traditional style charcoal making kiln. The basic concept is a simple chamber with a door on one end and a chimney on the other, insulated and sealed by being buried in clay soil, and roofed to keep off the rain. Carefully controlling the airflow into and out of the kiln during operation is the key to making quality charcoal with efficiency.
Softwood charcoal made in the kiln (preferably from Red Pine) will be chopped and screened for use in the workshop. Its primary end will be as fuel for the forge, but smaller sizes right down to the dust are used for specific purposes at other stages in the sword making process. For example, wet charcoal fines make up the insulating forge bed and charcoal dust makes up about a third of the yaki-ire clay mixture.
