The forge will be the heart with the blacksmith’s shop. It is from the forge how the blacksmith heats metal until it reaches a temperature and becomes malleable enough for him to use his other equipment to shape it.

The original blacksmith’s forge has evolved and grow modern-day as time passes, though the basic principles remain unchanged. The most frequent forge is the one fired by coal, charcoal or coke. The forge is a specially engineered fire the location where the temperature might be controlled so that the metal is heated to the temperature the blacksmith wants, depending on what he offers to do – shaping, annealing or drawing. The there main areas of the forge are:

· The hearth the place that the burning coke (or other fuel) is contained as well as over which the metal lies and heated.

· The Tuyere which is a pipe leading in the hearth through which air has. The effectiveness of the flames and also the heat it creates depends on how much air being fed with it over the Tuyere tube.

· The bellows will be the mechanism through which air needs with the Tuyere tube into the hearth. While earlier bellows were pumps run by muscles power, modern forges have high power fans or bowers to make air into the Tuyere

The blacksmith adjusts a combination of air and fuel inside the hearth the generate the exact temperature required to heat the metal. A normal blacksmith’s forge will have a flat bottomed hearth together with the Tuyere entering it from below. The core of the fire would have been a mass of burning coke in the heart of the hearth. For this burning coke is a wall of hot, however, not burning coal. This wall of coal serves two purposes. It provided insulation and has and focuses the temperature in the fire to some limited area, allowing the blacksmith to heat the metal within a precise manner. The hot coal also becomes transformed in coke which may then be used as fuel to the hearth.

The outer wall from the fire consist of a layer of raw coal, and this can be kept damp so as to control the warmth with the inner layer of hot coal to ensure that is may slowly "cook" into coke.

How big is the flames and also the heat it creates might be changed by either adding or removing fuel from it too and adjusting the air flow. By changing the design from the surface layers of coal, the form of the fire can be modified to fit the form from the metal piece being heated.

Many modern blacksmiths use gas forges. They are fueled by either gas main or propane. The gas is fed to the hearth, which can be lined by ceramic refractory materials, and blended with air and ignited. Pressure to succeed at which the gas has been fed in to the hearth might be adjusted to alter the temperature. While gas forges are simpler to use and require less maintenance and cleaning, the drawback is that, unlike a coal fired forge, the shape from the fire has limitations and should not be changed to accommodate the shape and size the metal being heated.
