The forge will be the heart in the blacksmith’s shop. It’s inside 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 developed and grow modern-day as time passes, nevertheless the fundamental principles remain unchanged. The most common forge may be the one fired by coal, charcoal or coke. The forge can be a specifically created open fireplace the place that the temperature can be controlled so that the metal is heated to the temperature the blacksmith wants, determined by what he promises to do - shaping, annealing or drawing. The there main areas of the forge are:

· The hearth where the burning coke (and other fuel) is contained well as over that your metal is put and heated.
· The Tuyere the industry pipe leading into the hearth by which air needs. Great and bad the hearth and also the heat it makes is dependent upon the quantity of air being fed with it from the Tuyere tube.
· The bellows would be the mechanism where air needs over the Tuyere tube in the hearth. While earlier bellows were pumps run by muscles power, modern forges have high power fans or bowers to force air in to the Tuyere

The blacksmith adjusts the mixture of air and fuel inside the hearth the generate the exact temperature needed to heat the metal. A traditional blacksmith’s forge will have a flat bottomed hearth using the Tuyere entering it from below. The core in the fire would have been a mass of burning coke down the middle of the fireside. 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 heat from the fire into a limited area, allowing the blacksmith to heat the metal in the precise manner. The new coal also becomes transformed in coke which can then be used as fuel to the hearth.

The outer wall in the fire comprises of a layer of raw coal, which are often kept damp so as to control heat in the inner layer of hot coal in order that is may slowly “cook” into coke.

How big is the hearth and also the heat it makes may be changed by either adding or removing fuel from it as well and adjusting the air flow. By changing the form with the surface layers of coal, the contour with the fire may also be modified to suit the shape with the metal piece being heated.

Many modern blacksmiths use gas forges. These are generally fueled by either propane or propane. The gas is fed in the hearth, which is lined by ceramic refractory materials, and when combined air and ignited. Pressure of which the gas is being fed in the hearth can be adjusted to vary the temperature. While gas forges are simpler to use and wish less maintenance and cleaning, the disadvantage is, unlike a coal fired forge, the shape of the fire has limitations and will not be changed to suit the shape and size of the metal being heated.
