Like a million others, I have a set of enameled cookware that has seen enough use that the enamel has boiled, burned, or chipped off down to the cast iron substrate. Surprisingly, the outer painted surface that takes direct fire is undamaged. It seems reasonable, then, that removing the inner enamel coat mechanically (grind or blast or peen) and applying a hard, high temperature coating (engine enamel or powder coat) would restore the finish and allow me to continue cooking/frying on the cookware. It seems a simple solution that can be done in any home back yard. However, the obvious question is whether the new coating would off-gas food-borne toxins into the food when heated.
I've searched many "Maker" websites and even asked a Major Manufacturer of one of the coatings and every answer I've gotten is, "Uh, I dunno. So maybe not."
Is it safe to cook/fry/bake/boil food safely on a painted surface?
(and you guys thought this wasn't a technical question)
