Input:
This container is plastic. There is no such thing as a safe microwaveable plastic, not withstanding the many microwavable foods sold in plastic. Studies consistently show nasty things like dioxins are given off in the microwave process. Far safer is large pyrex bowl with a lid (I use a pyrex pie pan).
