Brass is an alloy made of copper and zinc.
I don't have much experience with it myself. I did make one or the other piece, but my hands and wrists hated me for it, so I never got another spool of brass wire.
Luckily the other JAC members are not that shy about using brass, so I am able to present another Oldies but Goodies Challenge!
