    The forge may be the heart of 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 be newer as time passes, however the basic principles remain unchanged. The most frequent forge may be the one fired by coal, charcoal or coke. The forge can be a specially designed hearth the place that the temperature might be controlled so your metal is heated for the temperature the blacksmith wants, based on 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 other fuel) is contained well as over that your metal is placed and heated.

    · The Tuyere the pipe leading in to the hearth whereby air needs. The potency of the fireplace as well as the heat it makes depends on how much air being fed with it through the Tuyere tube.

    · The bellows would be the mechanism where air is forced over the Tuyere tube in the hearth. While earlier bellows were pumps operated by muscles power, modern forges have high power fans or bowers to force air into the Tuyere

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

    The outer wall in the fire comprises of a layer of raw coal, and this can be kept damp in an attempt to control the warmth in the inner layer of hot coal so that is may slowly "cook" into coke.

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

    Many modern blacksmiths use gas forges. These are generally fueled by either gas main or propane. The gas is fed in the hearth, that’s lined by ceramic refractory materials, and combined with air and ignited. Pressure at which the gas is being fed in to the hearth could be adjusted to alter the temperature. While gas forges are easier to use and wish less cleaning and maintenance, the downside is, unlike a coal fired forge, the shape from the fire has limitations and cannot be changed to fit the contour and sized the metal being heated.
