I have been told that burning (not heating to 400 degrees) powder releases
toxic material that can contaminate the food. This may vary with the
chemistry of individual powders and even the amount of toxicity may not be
significant in small quantities. All black pepper, for example, contains
aflatoxins, but you need to consume obscenely large amounts to be affected.
I have seen several ovens set out for trash pickup in my neighborhood. Usually
it's a bad element or thermostat (both cheap and easy to fix if the parts are
available), but sometimes just tossed for cosmetic reasons. But the drawback
to home kitchen ovens is their limited size. Commercial ovens would be bigger
and are surprisingly cheap at second-hand restaurant supply businesses, but
they are pretty big and usually gas (a no-no for powder, I'm told).
Is anyone aware of a do-it-youself powdercoating oven site? It shouldn't be
difficult to construct a panelized oven that can be
large/small/dissassembled and stored. Refractory cement is cheap; lighter
insulation is available. Electric heating elements, door seals, and
thermostats are readily available as repair parts.
