Once more, my mouth has opened too wide, or too late at night
(either one will do).
When I wrote about acrylic medium, my mind was still on the
sealing ceramic pieces thread. I have rarely seen acrylic medium used as
RESIST (but VERY often used to seal pieces).
What I wrote was geared towards sealing ceramic ware. My EXTREME
apologies to those confused. Everything there still holds true,
including sticking it in the oven. At lower temperatures, acrylic medium
is...yucky (I still can't think of a better word).
The big question is, what happens at higher temperatures? About
THIS, I do not know for sure. My instincts say, burning a material that
is, by nature, sort of a plastic, is not a good idea...but at very high
temperatures, I would think it would burn off completely...but I do not
have the first clue as to what gases may be introduced. As I said to
those who replied, when the manufacturers made this material, they had no
idea it would be burned! It is non toxic in it's wet or dry state, but
burned, I don't know.
Acrylic medium SOUNDS like the ideal resist...it's easy to apply,
not much smell and comparitively easy to clean up.
However (and my extreme apologies for this), my mind was not
thinking in terms of burning this stuff off! I have no ideas what the
risks are, but I feel compelled to do a bit of research and FIND OUT! I
think I will call the manufacturers of a few brands and let you all know
what they have to say. Like I say, they probably didn't think that
someone would decide to incinerate it. :)
Again, my sincere apologies for blabbing to the entire list with
my brain in neutral. While I do know a bunch of stuff about acrylic
paint (I was a painter before I was a potter), I never bothered to ponder
about burning it. Unless it happened to adorn a painting I particularily
hated. ;)
