I know I saw this somewhere but I can't seem to find it again after an hour of reading the forum! What are the numbers on plastic that are safe to use for CP molds? I was looking at a Stouffer's Mac N Cheese dish thinking it would be perfect to make two large bars in. It's got a 1 on the bottom. I'd think it is safe since you can put it in a 350° oven, but maybe the chemicals in soap make the difference not the heat?
