The forge is the heart from the blacksmith's shop. It is in the forge that this 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 changed and become newer with time, though the principles remain unchanged. The commonest forge may be the one fired by coal, charcoal or coke. The forge is really a specifically created fire place the location where the temperature may be controlled so the metal is heated on the temperature the blacksmith wants, according to what he offers 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 the metal is positioned and heated.
· The Tuyere the pipe leading in the hearth in which air is forced. The strength of the hearth and also the heat it makes depends on the volume of air being fed for it through the Tuyere tube.
· The bellows would be the mechanism where air is forced through 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 force air in to the Tuyere



The blacksmith adjusts the amalgamation of air and fuel from the hearth the produce the exact temperature necessary to heat the metal. A conventional blacksmith's forge have a flat bottomed hearth together with the Tuyere entering it from below. The main in the fire is a mass of burning coke in the heart of the fireside. Around this burning coke might be a wall of hot, but not burning coal. This wall of coal serves two purposes. It provided insulation and contains and focuses the heat of the fire to a limited area, allowing the blacksmith to heat the metal in the precise manner. The new coal also becomes transformed in coke which may then be utilized for fuel to the hearth.

The outer wall of the fire is made up of a layer of raw coal, and this can be kept damp to be able to control heat from the inner layer of hot coal in order that is may slowly "cook" into coke.

How big the fireplace and the heat it produces could be changed by either adding or removing fuel from this also and adjusting mid-air flow. By changing the shape in the surface layers of coal, the contour of the fire can even be modified to fit the form from the metal piece being heated.

Many modern blacksmiths use gas forges. They're fueled by either natural gas or propane. The gas is fed in the hearth, that is lined by ceramic refractory materials, and mixed with air and ignited. The stress of which the gas is being fed into the hearth can be adjusted to alter the temperature. While gas forges are easier to use and wish less cleaning and maintenance, the drawback is the fact that, unlike a coal fired forge, the shape with the fire is fixed and should not be changed to match the form and size of the metal being heated.
