The forge is the heart of the blacksmiths shop. It is inthe forge that the blacksmith heats metal until it reaches a temperature andbecomes malleable enough for him to use his other equipment to shape it. The traditional blacksmiths forge has evolved and becomemore sophisticated over time, but the basic principles remain unchanged. Themost common forge is the one fired by coal, charcoal or coke. The forge is aspecially designed fire place where the temperature can be controlled so thatthe metal is heated to the temperature the blacksmith wants, depending on whathe plans to do - shaping, annealing or drawing. The there main parts of theforge are:· The hearth where the burning coke (or otherfuel) is contained and over which the metal is placed and heated.· The Tuyere which is a pipe leading into thehearth through which air is forced. The strength of the fire and the heat itproduces will depend on the amount of air being fed to it through the Tuyeretube.· The bellows are the mechanism by which air isforced through the Tuyere tube into the hearth. While earlier bellows werepumps operated by muscles power, modern forges have high power fans or bowersto force air into the Tuyere The blacksmith adjusts the mixture of air and fuel in thehearth the produce the exact temperature needed to heat the metal. Atraditional blacksmiths forge will have a flat bottomed hearth with the Tuyereentering it from below. The core of the fire will be a mass of burning coke inthe center of the hearth. Around this burning coke will be a wall of hot, butnot burning coal. This wall of coal serves two purposes. It provided insulationand contains and focuses the heat of the fire to a limited area, allowing theblacksmith to heat the metal in a precise manner. The hot coal also becomestransformed in coke which can then be used as fuel for the hearth. The outer wall of the fire is made up of a layer of rawcoal, which is often kept damp so as to control the heat of the inner layer ofhot coal so that is may slowly cook into coke. The size of the fire and the heat it produces can be changedby either adding or removing fuel from it as well and adjusting the air flow.By changing the shape of the outer layers of coal, the shape of the fire canalso be modified to suit the shape of the metal piece being heated. Many modern blacksmiths use gas forges. These are fueled byeither natural gas or propane. The gas is fed into the hearth, which is linedby ceramic refractory materials, and mixed with air and ignited. The pressureat which the gas is being fed into the hearth can be adjusted to vary thetemperature. While gas forges are easier to use and require less maintenanceand cleaning, the drawback is that, unlike a coal fired forge, the shape of thefire is fixed and cannot be changed to suit the shape and size of the metalbeing heated.
