Micro-Charring for Pigment, Tinder or Medicine To read about what charcoal is, see The History of Charcoal .

Apart from its use as a fuel for smelting, smithing and domestic heating, charcoal has a long history of use as pigment, tinder and medicine. Pigment Charcoal is a black substance that does not decay; it is completely light-fast (will not fade when exposed to sunlight) and chemically stable (it will not oxidize or change color over time). This makes it very useful in artwork and for writing. The oldest use of charcoal outside of a hearth was as pigment for drawing and painting on cave walls, more than 30,000 years ago. Sketching with charcoal sticks remained popular throughout human history and continues today. Painting with finely ground charcoal developed into a specialized ar

To read about the crucible method of producing charcoal, see Micro-Charring .  To read about wood preservation, see Charring Fence Posts . Creating charcoal begins with preparing a burn site. With the mound method, this means scraping clean a level, above-ground surface, cleared to prevent the spread of fire. This can include building earthwork sides or half-walls to reduce the labor of enclosing the burn pile. However, a safer and more certain method is to dig a trench or pit hearth, and to conduct the charcoal burn below grade. Burning within a sheltering bank of earth provides two major benefits, compared with open mounds: 1) It reduces the dirt-shoveling labor involved in repeated burns, so long as the same site is used each time. Rather than having to cover an entire mound with dirt every time a charcoal mound is fired, th
