well technically the paint is mostly plastic so at about 175C it should be alright (might run a little) but probably biggest issue would be off-gassing as it partially melts. There are topics about it for baking acrylic on glass, but they are talking about some specific craft paint that can withstand heat. Best bet would be to just get a small piece of metal (could probably just use aluminum foil) and see what happens. I would probably use a toaster oven instead of the house oven just in case something goes bad or there are some bad smelling fumes that might not go away and that way you could do it out doors so the house doesn't smell. Also, make sure your paints are free of anything like Cadmium or Cobalt as they could cause toxic fumes when heated.
