The five basic forging processes are often combined to produce and refine the shapes necessary for finished products. For example, to fashion a cross-peen hammer head, a smith would start with a bar roughly the diameter of the hammer face: the handle hole would be punched and drifted (widened by inserting or passing a larger tool through it), the head would be cut (punched, but with a wedge), the peen would be drawn to a wedge, and the face would be dressed by upsetting.

London was the largest with a population of 10,000 and Winchester the second largest with 6,000 people. The Domesday Book gives some idea about what life in towns was like . Coal is a natural mineral that forms over the span of millions of years while charcoal is a manufactured product created from wood

These operations generally require at least a hammer and anvil, but smiths also use other tools and techniques to accommodate odd-sized or repetitive jobs.In forge welding, the pieces to join are heated to what is generally referred to as welding heat. For mild steel most smiths judge this temperature by color: the metal glows an intense yellow or white. At this temperature the steel is near molten. Iron is a naturally occurring metallic element. It is almost never found in its native form (pure iron) in nature. It is usually found as an oxide or sulfide, with many other impurity elements mixed in. Drawing does not have to be uniform. A taper can result as in making a wedge or a woodworking chisel blade. If tapered in two dimensions, a point results. Some areas had watchmen or constables who would patrol the area to prevent crimes. Most minor crimes were dealt with by the local lord. A judge, who was appointed by the king, travelled to each county to deal with serious crimes. a b Davis, J.R. (1998). Metals Handbook, 2nd Ed. Materials Park, OH 44073-0002: ASM International.

Bending can be done with the hammer over the horn or edge of the anvil or by inserting a bending fork into the hardy hole (the square hole in the top of the anvil), placing the work piece between the tines of the fork, and bending the material to the desired angle. Bends can be dressed and tightened, or widened, by hammering them over the appropriately shaped part of the anvil. Grinding stones, abrasive paper, and emery wheels can further shape, smooth, and polish the surface. Another common technique was welding. Welding is the process of joining two pieces of metal together by heating them until they melt and then hammering them together. Drawing lengthens the metal by reducing one or both of the other two dimensions. As the depth is reduced, or the width narrowed, the piece is lengthened or "drawn out."In the medieval period, there was no organised police force and most law enforcement was organised by local people. In some areas, every male over the age of 12 had to join a group called a tithing , and they had to make sure no one else in the group committed a crime. If someone was the victim of a crime, they had to raise the ‘hue and cry’, meaning other villagers had to come to help find the criminal. An Aide-Memoire to the Military Sciences volume 1 by Royal Engineers, British Service, 1845, Col. G.G. Lewis, senior editor Heating iron to a "forging heat" allows bending as if it were a soft, ductile metal, like copper or silver. Main features of Neoclassicism ironwork (also referred to as Louis XVI style and Empire style ironwork) include smooth straight bars, decorative geometric elements, double or oval volutes and the usage of elements from Classical antiquity ( Meander (art), wreaths etc.). Forging—the process smiths use to shape metal by hammering—differs from machining in that forging does not remove material. Instead, the smith hammers the iron into shape. Even punching and cutting operations (except when trimming waste) by smiths usually re-arrange metal around the hole, rather than drilling it out as swarf.

Narrator: Most people in medieval England were farming peasants who lived in villages in the countryside. They had a hard life working all day on farms owned by nobles. By the 12th century this was changing. New towns developed around religious buildings, castles or trade routes. These towns were crowded, noisy and smelly. At dawn, a bell would ring to begin the day. Townspeople would attend their first religious mass of the day. Steel is an alloy of iron and between 0.3% and 1.7% carbon by weight. The presence of carbon allows steel to assume one of several different crystalline configurations. Macroscopically, this is seen as the ability to "turn the hardness of a piece of steel on and off" through various processes of heat-treatment. If the concentration of carbon is held constant, this is a reversible process. Steel with a higher carbon percentage may be brought to a higher state of maximum hardness.

These metals are all quite malleable, and humans' initial development of hammering techniques was undoubtedly applied to these metals. The Romans (who ensured that their own weapons were made with good steel) noted (in the 4th century BC) that the Celts of the Po River Valley had iron, but not good steel. The Romans record that during battle, their Celtic opponents could only swing their swords two or three times before having to step on their swords to straighten them.

As an example of drawing, a smith making a chisel might flatten a square bar of steel, lengthening the metal, reducing its depth but keeping its width consistent. The smith first cleans parts to be joined with a wire brush, then puts them in the fire to heat. With a mix of drawing and upsetting the smith shapes the faces so that when finally brought together, the center of the weld connects first and the connection spreads outward under the hammer blows, pushing out the flux (if used) and foreign material.

During the Chalcolithic era and the Bronze Age, humans in the Mideast learned how to smelt, melt, cast, rivet, and (to a limited extent) forge copper and bronze. Bronze is an alloy of copper and approximately 10% to 20% Tin. Bronze is superior to just copper, by being harder, being more resistant to corrosion, and by having a lower melting point (thereby requiring less fuel to melt and cast). Much of the copper used by the Mediterranean World came from the island of Cyprus. Most of the tin came from the Cornwall region of the island of Great Britain, transported by sea-borne Phoenician and Greek traders. Photo by Hans Splinter.

They seem to have maintained a near monopoly on the knowledge of iron production for several hundred years, but when their empire collapsed during the Eastern Mediterranean upheavals around 1200 BC, the knowledge seems to have escaped in all directions. In the final part of the 18th century, forged ironwork continued to decline due to the aforementioned industrial revolution, shapes of the elements in the designs of window grilles and other decorative functional items continued to contradict natural forms, surfaces begin to be covered in paint, cast iron elements are incorporated into the forged designs. Elizabeth Brim, noted for feminine imagery of lingerie or shoes in her work, also for the Brim technique of inflating balloons of hot metal with compressed air.Any foreign material in the weld, such as the oxides or "scale" that typically form in the fire, can weaken it and cause it to fail. Thus the mating surfaces to be joined must be kept clean. To this end a smith makes sure the fire is a reducing fire: a fire where, at the heart, there is a great deal of heat and very little oxygen. The smith also carefully shapes mating faces so that as they come together foreign material squeezes out as the metal is joined. To clean the faces, protect them from oxidation, and provide a medium to carry foreign material out of the weld, the smith sometimes uses flux—typically powdered borax, silica sand, or both.
