Clarification on the Coppery Black. I found the part I was looking for. It was an email to RareRipes. It's not that you can't anneal, but most of us aren't going to buy a new annealer to be able to make the coppery black work. Here is what was said in the email:

"As you probably know, the Coppery Black is a fussy one. I guess anything
beautiful is never easy. Anyway, I have found it is best to anneal the
Coppery Black directly from the torch, rather than batch anneal from cold.
If you can do that, you should have better luck. Another thing that can
affect the copper sheen is the oxygen content in the kiln, believe it or
not. I have had the best luck annealing the Coppery Black with our mini
annealer since it remains open at all times, allowing air in. I know you
don't have one of these, but experimenting with the opening on your kiln may
help.

One more thing I have found. The Coppery Black has a base glass of the Op.
Hi Density Black. It is a very dense glass. I have found that the beads do
very well without annealing. I rarely lose any of them to cracking, and I
have a lot that I never annealed, something also to consider if you continue
to have problems."
