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

The original blacksmith’s forge has evolved and become newer over time, but the basic principles remain unchanged. The most common forge may be the one fired by coal, charcoal or coke. The forge is a specially designed fire place in which the temperature can be controlled in order that the metal is heated to the temperature the blacksmith wants, according to what he intends to do - shaping, annealing or drawing. The there main parts of the forge are:

· The hearth the place that the burning coke (or any other fuel) is contained and also over that your metal is placed and heated.
· The Tuyere the industry pipe leading into the hearth by which air is forced. The effectiveness of the fire as well as the heat it produces depends on the amount of air being fed with it through the Tuyere tube.
· The bellows will be the mechanism in which air has with the Tuyere tube in to the hearth. While earlier bellows were pumps run by muscles power, modern forges have high power fans or bowers to make air in to the Tuyere

The blacksmith adjusts the mixture of air and fuel inside the hearth the generate the exact temperature had to heat the metal. A regular blacksmith’s forge will have a flat bottomed hearth using the Tuyere entering it from below. The core from the fire would have been a mass of burning coke during the hearth. Surrounding this burning coke might be a wall of hot, but not burning coal. This wall of coal serves two purposes. It provided insulation and possesses and focuses the warmth of the fire to a limited area, allowing the blacksmith to heat the metal within a precise manner. The coal also becomes transformed in coke that may then be part of fuel to the hearth.

The outer wall of the fire consist of a layer of raw coal, which are often kept damp in an attempt to control the warmth from the inner layer of hot coal to ensure is may slowly “cook” into coke.

How big the hearth along with the heat it makes might be changed by either adding or removing fuel as a result at the same time and adjusting mid-air flow. By changing the design with the surface layers of coal, the shape with the fire can also be modified to match the form with 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 is lined by ceramic refractory materials, and combined with air and ignited. Pressure of which the gas has been fed in to the hearth may be adjusted to alter the temperature. While gas forges are easier to use and wish less cleaning and maintenance, the drawback is that, unlike a coal fired forge, the shape with the fire has limitations and can’t be changed to accommodate the design and height and width of the metal being heated.
