Metallurgy is a domain of materials science and engineering that studies the physical and chemical behavior of metallic elements, their inter-metallic compounds, and their mixtures, which are known as alloys.
A blacksmith is a metalsmith who creates objects primarily from wrought iron or steel, but sometimes from other metals, by forging the metal, using tools to hammer, bend, and cut. Blacksmiths produce objects such as gates, grilles, railings, light fixtures, furniture, sculpture, tools, agricultural implements, decorative and religious items, cooking utensils, and weapons. There was an historical distinction between the heavy work of the blacksmith and the more delicate operation of a whitesmith, who usually worked in gold, silver, pewter, or the finishing steps of fine steel. The place where a blacksmith works is called variously a smithy, a forge or a blacksmith's shop.
Metalworking is the process of shaping and reshaping metals to create useful objects, parts, assemblies, and large scale structures. As a term it covers a wide and diverse range of processes, skills, and tools for producing objects on every scale: from huge ships, buildings, and bridges down to precise engine parts and delicate jewelry.
An anvil is a metalworking tool consisting of a large block of metal, with a flattened top surface, upon which another object is struck.
A silversmith is a metalworker who crafts objects from silver. The terms silversmith and goldsmith are not exact synonyms, as the techniques, training, history, and guilds are largely the same but differed in that the end product may vary greatly.
Gilding is a decorative technique for applying a very thin coating of gold over solid surfaces such as metal, wood, porcelain, or stone. A gilded object is also described as "gilt". Where metal is gilded, the metal below was traditionally silver in the West, to make silver-gilt objects, but gilt-bronze is commonly used in China, and also called ormolu if it is Western. Methods of gilding include hand application and gluing, typically of gold leaf, chemical gilding, and electroplating, the last also called gold plating. Parcel-gilt objects are only gilded over part of their surfaces. This may mean that all of the inside, and none of the outside, of a chalice or similar vessel is gilded, or that patterns or images are made up by using a combination of gilt and ungilted areas.
Repoussé or repoussage ( ) is a metalworking technique in which a malleable metal is shaped by hammering from the reverse side to create a design in low relief. Chasing or embossing is a similar technique in which the piece is hammered on the front side, sinking the metal. The two techniques are often used in conjunction.
A rivet is a permanent mechanical fastener. Before being installed, a rivet consists of a smooth cylindrical shaft with a head on one end. The end opposite the head is called the tail. On installation, the deformed end is called the shop head or buck-tail.
Mokume-gane (木目金) is a Japanese metalworking procedure which produces a mixed-metal laminate with distinctive layered patterns; the term is also used to refer to the resulting laminate itself. The term mokume-gane translates closely to 'wood grain metal' or 'wood eye metal' and describes the way metal takes on the appearance of natural wood grain. Mokume-gane fuses several layers of differently coloured precious metals together to form a sandwich of alloys called a "billet." The billet is then manipulated in such a way that a pattern resembling wood grain emerges over its surface. Numerous ways of working mokume-gane create diverse patterns. Once the metal has been rolled into a sheet or bar, several techniques are used to produce a range of effects.
Metal fabrication is the creation of metal structures by cutting, bending and assembling processes. It is a value-added process involving the creation of machines, parts, and structures from various raw materials.
Filigree is a form of intricate metalwork used in jewellery and other small forms of metalwork.
Sinking, also known as doming, dishing or dapping, is a metalworking technique whereby flat sheet metal is formed into a non-flat object by hammering it into a concave indentation. While sinking is a relatively fast method, it results in stretching and therefore thinning the metal, risking failure of the metal if it is "sunk" too far.
Huaca Rajada, also known as Sipán, is a Moche archaeological site in northern Peru in the Lambayeque Valley, that is famous for the tomb of Lord of Sipán, excavated by Walter Alva and his wife Susana Meneses beginning in 1987. The city of Sipán is dated from 50–700 AD, the same time as the Moche Period.
A tinsmith is a person who makes and repairs things made of tin or other light metals. The profession may sometimes also be known as a tinner, tinker, tinman, or tinplate worker; whitesmith may also refer to this profession, though the same word may also refer to an unrelated specialty of iron-smithing. By extension it can also refer to the person who deals in tinware, or tin plate. Tinsmith was a common occupation in pre-industrial times.
Metalworking hand tools are hand tools used in the metalworking field, powered entirely by the operator. There are lots of tools, fit for different actions to the material, such as shrinking or modifying its surface.
The English wheel, in Britain also known as a wheeling machine, is a metalworking tool that enables a craftsperson to form compound curves from flat sheets of metal such as aluminium or steel.
Planishing is a metalworking technique that involves finishing the surface of sheet metal by finely shaping and smoothing it.
Bidriware is a metal handicraft from the city of Bidar in Karnataka, India. It was developed in the 14th century C.E. during the rule of the Bahmani Sultans. The term "bidriware" originates from the township of Bidar, which is still the chief center of production. The metal used is white brass that is blackened and inlaid with silver. As a native art form, Bidriware obtained a Geographical Indications (GI) registry on 3 January 2006.
In metallurgy, cold forming or cold working is any metalworking process in which metal is shaped below its recrystallization temperature, usually at the ambient temperature. Such processes are contrasted with hot working techniques like hot rolling, forging, welding, etc. The same or similar terms are used in glassmaking for the equivalents; for example cut glass is made by "cold work", cutting or grinding a formed object.
Metal spinning, also known as spin forming or spinning or metal turning most commonly, is a metalworking process by which a disc or tube of metal is rotated at high speed and formed into an axially symmetric part. Spinning can be performed by hand or by a CNC lathe.
