The forge is the heart in the blacksmith’s shop. It’s within the forge the blacksmith heats metal until it reaches a temperature and becomes malleable enough for him to work with his other equipment to shape it.

The standard blacksmith’s forge has developed and turn into newer with time, but the basics remain unchanged. The most typical forge will be the one fired by coal, charcoal or coke. The forge is a specially designed open fireplace in which the temperature may be controlled so your metal is heated towards the temperature the blacksmith wants, according to what he plans to do - shaping, annealing or drawing. The there main elements of the forge are:

· The hearth the place that the burning coke (and other fuel) is contained and also over that the metal lies and heated.
· The Tuyere which is a pipe leading in the hearth by which air needs. The potency of the hearth along with the heat it produces is determined by the quantity of air being fed to it from the Tuyere tube.
· The bellows will be the mechanism through which air needs through the Tuyere tube to the hearth. While earlier bellows were pumps operated by muscles power, modern forges have high power fans or bowers to push air in the Tuyere

The blacksmith adjusts the mix of air and fuel in the hearth the generate the exact temperature required to heat the metal. A conventional blacksmith’s forge may flat bottomed hearth with all the Tuyere entering it from below. The core from the fire is a mass of burning coke in the center of the fireside. Surrounding this burning coke is a wall of hot, although not burning coal. This wall of coal serves two purposes. It provided insulation and has and focuses heat from the fire with a limited area, allowing the blacksmith to heat the metal inside a precise manner. The new coal also becomes transformed in coke which could then be used as fuel for that hearth.

The outer wall from the fire is made up of a layer of raw coal, that is kept damp so as to control the warmth in the inner layer of hot coal in order that is may slowly “cook” into coke.

The size of the flames as well as the heat it generates could be changed by either adding or removing fuel from that also and adjusting mid-air flow. By changing the shape of the surface layers of coal, the contour with the fire can be modified to accommodate the design from the metal piece being heated.

Many modern blacksmiths use gas forges. These are fueled by either propane or propane. The gas is fed to the hearth, that’s lined by ceramic refractory materials, and combined with air and ignited. The pressure from which the gas has fed to the hearth can be adjusted to alter the temperature. While gas forges are easier to use and require less cleaning and maintenance, the disadvantage is always that, unlike a coal fired forge, the shape in the fire has limitations and can’t be changed to match the form and height and width of the metal being heated.
