I'm coming in late, here (been up to my eyeballs in alligators,
now have three hundred Orchid emails) but it occurs to me that the
argentium experiment might have gone wrong because the metal was
"enclosed in a pyrex container". If the lid was close fitting,
this would severely limit the amount of oxygen available to the
metal, thus defeating the purpose, no?
My gosh, Noel----you are brilliant! Of course! I had focused on
the insulation factor, but that probably is not as significant as
the oxygen factor. Folks were hoping not to have any ill effects
from their dirty ovens by enclosing in pyrex. In fact, though, any
discoloration generally comes off in pickle. The exception may be
the exceptionally dirty oven that is dirty enough that it
smokes.....but in that case, it really is time to clean anyways,
don't you think?
Another interesting thing is that following my suggestion of leaving
the lid off to cut down on the insulation factor also allows the
oxygen in. So, folks, let's forget the enclosed container idea, ok?
Thanks so much for pointing out what we all should have seen----hind
sight is an amazing thing, isn't it?
By the way, I am about to send my laptop off for repair, and then
off to Haystack for two weeks, so I don't know whether I'll be
available much between now and September. So, remember
firstname.lastname@example.org as a resource.....(as well as Trevor and all
the other brilliant minds on Orchid.)
