Many people are unaware of the fact that copper work-hardens, the
more you flex it the stiffer it gets, silver does this too. To make
either silver or copper tubing and small gauge wire workable you
should anneal (Sp.?) it! This can be easily done in the home oven, set
the oven for 400 to 500 degrees F. and put the wire or tubing in and
let it heat for about an hour then turn the oven off allow it to cool
over night. You will now find the tubing or wire very easy to work.
Of course as you work it it will harden again and you can repeat the
annealing until the job is done.
