The little blue one seemed to melt a bit and stuck to aluminum baking pans after baking. When we pulled them out there were bruises on the aluminum bottom of the pot that we couldn't scrub away. We ended up cutting small circles out of parchment paper and placing them in the bottom of the baking dish to keep the foil cups from sticking and it worked really well but it would have been a lot better if we didn't have to.
