The text on the sign reads:

Charcoal Making

Charcoal, which resembles coal, is a brittle, lightweight, black porous substance that is 85% to 98% carbon. It is produced by slowly heating wood in a kiln. This process, called pyrolysis, removes the water and volatile compounds from the organic material without burning it. For centuries, charcoal was favored as a fuel source because it burns hotter, cleaner, and more slowly than wood.

Much of the charcoal made at Piedmont was sent by railroad to mining ore smelters in Utah's Salt Lake Valley. Charcoal, which burns at more than 2,000° F, is used in smelting - a process of extracting metal, such as lead or copper, from its ore. Charcoal was also shipped to Fort Bridger as fuel for the blacksmith forges.

Workers filled the kilns with about 30 cords of pine logs, harvested in the nearby mountains. The logs were packed tight and double-stacked, end-to-end. The wood was lit, but not allowed to fully burn, just smolder. Charcoal makers controlled the heat by plugging small air vent holes around the base of the kiln. It took six to eight days of slow firing to reduce the wood to charcoal. Cooling took another five days. On average, 100 parts of wood yielded about 25 parts of charcoal, by weight.
