A coppersmith, also known as a redsmith, is a person who makes artifacts from copper. The term redsmith comes from the colour of copper.

Examples of objects made by modern coppersmiths

These include:-

• jewellery, sculptures, weather vanes, overmantels, fenders, decorative panels, and challenge shields;
• plates and cookware, cigarette cases, tobacco jars, tea and coffee pots, jugs, vases, trays, frames, rose bowls;
• awnings, light fixtures, fountains, range hoods, cupolas, and stills.

Notable copper styles in the UK include Newlyn in Cornwall and Keswick in Cumbria. Coppersmith work started waning in the late 1970s and early 1980s and those in the sheetmetal trade began doing the coppersmith's work, the practices used being similar to those in the plumbing trade. Coppermiths in recent years have turned to pipe work, not only in copper but also stainless steel and aluminium, particularly in the aircraft industry. They are one of the few trades that have a mention in the Bible.^[1]

Properties of copper

Copper is generally considered to be a soft metal, meaning it can be worked without heating. Over a period of working the metal in this way it can "work-harden". This means that the molecules within the copper are compressed and irregular in their arrangement. This causes stress in the metal and eventually cracking the metal along these stress points. In order for the copper to be worked to any extensive degree it must be annealed. This process involves heating the metal and then rapidly cooling it in water. The cooling stage is known as quenching. By heating the copper, the molecules in the metal are relaxed, and thus able to align themselves in a more uniform fashion. This allows for easier shaping of the metal. In order to keep this uniformity within the metal, it is cooled instantly. This prevents the molecules from moving around and causing tension in the structure of the metal. Unlike ferrous metals—which must be cooled slowly to anneal—copper can be cooled slowly in air or quickly by quenching in water.

In regions where copper is mined like Iberia and India there are a number of centres where the coppersmith trade has flourished.
