The particular emphasis was on foundry and forge technology to meet the demand of trained manpower in the primary metal manufacturing sectors like automobile, heavy engineering, machine and component manufacturing etc. Two carefully designed advanced diploma courses, namely foundry and forge technology, were offered.

In more recent excavations, hammerscale recovery has been conducted in a more systematic manner, using the grid method noted above. For example, in an excavation in 1992, by means of establishing a grid and collecting local samples, the former location of a hearth and an anvil was determined despite the lack of the direct remains of either.

Forging a nail. Valašské muzeum v přírodě, Czech Republic. Forging is one of the oldest known metalworking processes. [1] Traditionally, forging was performed by a smith using hammer and anvil, though introducing water power to the production and working of iron in the 12th century allowed the use of large trip hammers or power hammers that increased the amount and size of iron that could ...
Brew in a bag (BIAB) is a simplified all-grain technique developed in Australia. [54] The main pioneer and continuing authority on this method is Patrick Hollingdale. [54] The hallmarks of BIAB are a single brewing vessel, a fine mesh bag to hold the grist (crushed malt/grain) and a single heat source.
Through the 19th and very early 20th centuries, this method of construction evolved to produce extremely high quality anvils. The basic process involved forge-welding billets of wrought iron together to produce the desired shape. The sequence and location of the forge-welds varied between different anvil makers and the kind of anvil being made.
In Germany, tilt hammers of up to 300 kg were used in hammer mills to forge iron. Surviving, working hammers, powered by water wheels, may be seen, for example, at the Frohnauer Hammer in the Ore Mountains. The belly helve hammer was the kind normally found in a finery forge, used for making pig iron into forgeable bar iron. This was lifted by ...
Two typical methods using only hammer and anvil would be hammering on the anvil horn, and hammering on the anvil face using the cross peen of a hammer. Another method for drawing is to use a tool called a fuller, or the peen of the hammer, to hasten the drawing out of a thick piece of metal. (The technique is called fullering from the tool.)
The metal (known as the "workpiece") is transported to and from the forge using tongs, which are also used to hold the workpiece on the smithy's anvil while the smith works it with a hammer. Sometimes, such as when hardening steel or cooling the work so that it may be handled with bare hands, the workpiece is transported to the slack tub ...
