Well, in all seriousness Susan, what do you really know about this? It is
very likely that polymer clay emits toxic fumes during firing, and it is
likely that those fumes can deposit residual compounds on the oven walls,
which could revolatilize and contaminate food. Do you have any good reason
at all to be sceptical of this?
You are making assumptions that you have no right to make, especially when
people's health is at risk. Please leave such judgements to the experts.

Hello Vince
I was asked to test "cold clay" for summer circle where they did not
have a kiln-white and red types. Kind of red clay and ball clay perhaps
with some bentonite and a binder that in +- 170C 340 F become firm.
The first thing that shocked me when I opened the package was the
terrible smell of the binder. I tested it in my kiln. I doubt if I would
use it at home.
