I felt like I have heard it and maybe have done it a while ago but I am not 100% sureI will be cooking a Boston Butt in the oven for 12 hours at 225 degrees, which I did over Thanksgiving but it was just a tad drier that I had hoped so I am hoping that the plastic wrap would keep some of the moisture in.
Yes, it meltsAnd even when you heat up food in the microwave it can happenPlus, if it doesn't melt it still gives off artificial hormones from the compounds that the plastics are made fromOne Dartmouth University Study showed that plastic wrap heated in a microwave oven with vegetable oil had 500,000 times the minimum amount of xenoestrogens needed to stimulate breast cancer cells to grow in the test tubeThe xenoestrogens are proven to come from heated plastic wrapIt's something most people don't knowSo you definitely shouldn't use it in a real oven!
Aluminum sulfate is: Al2(SO4)3 Aluminum hydroxide and sulfuric acid form when it is hydrolyzed, so the opposite reaction will yield your aluminum sulfate (every reaction can go backwards, unless it is a strong base/acid!)
