Agnes has given us some valuable about disposing of
pickle and has alleviated my concern about copper and silver residue.
However, I did find some disturbing about heating brass.
Some of it consists of 30% or more of zinc, and the balance is
copper. I learned this from an article written by Charles Lewton
Brain, which is on the Orchid website.
I referred to the article as I had a strange occurrence in the studio
when I was annealing a 1"X6" 16 gauge strip of brass planning to
runit through the rolling mill to reduce it to 18 gauge and Suddenly
my smoke detector alarm went off. I immediately shut off the torch,
but could not detect any smell of smoke. I resumed trying to
annealthe brass, and the alarm went off again. I quenched the brass
and set it aside.
I do a lot of annealing of silver, and lately some copper as I am
using thecopper in practicing anticlastic raising. Never, had the
alarmgo off before.
For a test I took a large piece of copper, and set about annealing
it. No problem. The alarm was silent.
Obviously it was fumes from the brass that triggered it, in all
probability the zinc content. or whatever else is in it. As I had
purchased the batch of brass at a garage sale, I I did learn that
brasses are composed of different compositions, but have no idea
about the composition of the batch I go. However, after receiving the
warning from my smoke detector, I have no intention of trying to heat
the brass again.
I never use brass, but as I had these on hand thought I could do
something interesting with them. Not a good idea. Alma
