Topic: two cans and a drill - heat and can lining (3 msgs / 83 lines)
1) From: Sam49
A reply post regarding cans over the stove burner raises the question of 
the impact of the high heat on the lining material for food containing cans.
There is no definitive answer, but the heat from the burner will 
certainly be in excess of 500 degrees F if it is going to be hot enough 
to roast the beans.
I wouldn't try this one without answering that question first.
I gave up pursuing the HGBM method due to concerns about the toxic fumes 
from the non-stick lining in the dough bowl where the beans would be 
roasting.   Heat guns are putting out temps quite a bit above those 
necessary to generate the fumes from the non-stick coating.
I know some dismiss this issue, but I think it is a real concern.

Yeah, that would be a bit of a poser, if you used a non-stick lined
bowl.  Luckily, I didn't have a dog bowl handy, so I used a a plain,
non-lined stainless steel mixing bowl.  It's retired now - I got tired
of fighting the ever-changing (but always chilly) porch environment,
but the small bowl worked fine for 4 oz, and I'm pretty sure it was
limited by the heat source vs air temp; at least half again would
probably work mechanically, and that was a smallish mixing bowl.
