Annealing copper

[RJSakowski]

In my experience a soak isn't required for annealing copper. Certainly, not an extended soak. It may be due to the high thermal conductivity drawing heat away as you anneal it. By the time you reach a higher annealing temperature, the annealing process has begun.

The references to lower temperature annealing ythat I had seen were for wire drawing processes and they did use an extended soak time.

Perhaps a BBQ or cook stove?

I had wondered about that, too. I have a single-burner propane stove we use for canning. It's used outside so we don't heat up the house too much during the process. It seems that canning almost always needs to happen during the hottest days of the year so having a version of an outdoor kitchen can be handy.

Thanks for the suggestion!

Good info, thanks.
