dremd,
Thanks for running the test.
I have done silver soldering before, and I was able to do it easily with a regular propane torch.
When I tried to braze refrigeration line, the propane didn't get things hot enough. I found it necessary to use MAPP gas and a turbo torch. The turbo torch and propane still would not work.
So I have to heat everything up really hot, to cherry red...
Were you getting the copper heated to cherry red in your test? It could surely make a difference in oxidation.
Thanks,
