As proposed, someone should definitely merge this with redsmith. They are the same thing! I'd do this if I knew the process. Maybe someone with the knowledge cares enough?

- My grandfather was a coppersmith in the RAF during the 1940s and later. He didn't specialise in artistic work, although my Grandmother had a model of a spitfire he cast from a single (old UK) penny. His work was on aircraft maintenance in copper, brass and bronze. No one in my family has ever heard of a 'redsmith' =- perhaps its a US term?

Does one quench copper? I thought quenching was for ferrous metals, and was a hardening technique. This needs to be fixed in the article. It starts out saying annealing, then describes quenching. PuggBottom (talk) 20:34, 14 July 2009 (UTC)[reply]

Working with copper has much in common with the working of alloys of copper like brass (brazing)

Phew this article needs a grammar tidy up, but not tonight! My grandfather was a coppersmith in the RAF, this article misses that a great deal of the work is in brass and bronze. Pipework, manifolds, floats, engine part, brazing. Stub Mandrel (talk) 02:00, 13 November 2017 (UTC)[reply]

The article claims that copper was probably the first metal used by humans. That seems unlikely; gold must have been user much earlier. Gold can be found pure in nature. Nuggets can be welded into larger blocks and formed into any shape by cold hammering. Gold can also be cold-hammered into thin sheets, which can then be formed by repoussé or chasing into complicated objects. Native copper is much rarer, and is nowhere as workable. It probably did not see significant use until humans learned how to smelt and cast it. --Jorge Stolfi (talk) 14:54, 19 April 2019 (UTC)[reply]
