I was looking online for factual information but have not been able to find anything definitive yet. I do remember reading a while back that batting designed for the microwave has been cleaned/processed more than other 100% cotton battings to ensure it contains no scrim or other metal fragments. Whatever I read stated that even though batting may be 100% cotton, it still contains some degree of metal and other materials due to the manufacturing and cleaning process which causes problems in the microwave. Wish I could remember where I found that information.........but so far no luck.
