ELI5: What makes something microwaveable or non-microwaveable? Is all food microwaveable?

Yeah, all food is microwaveable (well, unless it has gold or silver leaf in it as some pastries may).

Non-microwaveable cookware absorbs microwave radiation and so it'll get hot, and also prevent the food from getting hot.  That's all.

Microwaveable cookware generally does not absorb much microwave radiation.
