Joe sez:

wire
and heat them cherry red with the propane torch and them quench in a bucket
of
water, they will be soft again. Though there is sort of a limit to how many
times you can get away with this.

As others have pointed out, when annealing copper it doesn't matter
whether you quench or not. The result is the same. I don't bother.
Maybe Joe is in more of a hurry to cool down those hot washers.

Chilling them knocks the oxidation scab off the washer. Then you use 1500
grit on a piece of glass to make them smooth.

Please note
Brass is what is called "hot short" and any heating will tend to harden it
and it becomes very brittle.
