[1] They had to live near the kiln, usually in a charcoal burner's hut (Köhlerhütte or Köte in Germany, Austria and Switzerland). During the Middle Ages ...
Apart from structural wood preservation measures, there are a number of different chemical preservatives and processes (also known as timber treatment, lumber treatment or pressure treatment) that can extend the life of wood, timber, and their associated products, including engineered wood. These generally increase the durability and resistance ...
A charcoal burner tending his charcoal clamp, in which he is producing charcoal. The process takes days, and the clamp has to be monitored to stop the fire from breaking out (technically, the oxygen from breaking in). Coke and charcoal are both produced by charring, whether on an industrial scale or through normal combustion of coal or wood ...
Fire hardening is the process of removing moisture from wood, changing its structure and material properties, by charring it over or directly in a fire or a bed of coals. . This has been thought to make a point, like that of a spear or arrow, or an edge, like that of a knife or axe, more durable and efficient for its use as a tool or we
There is reference to using wood chips - and each wood will give a different hugh when burned to charcoal -- Just as ANY beginning BBQ-er if Apple wood and Peach wood -- even when burned to black charcoal give off a different flavor for the wood-- or if you BBQ in black-oak, THEN follow that by apple and Cherry -- if the flavor is the same is ...
