The internet doesn't help.

Wtf is that?

It feels plasticky and hard. But I don't think it's happy to see me since it's broken in half and I probably did it when cleaning it.

If you help me figure out what it is, I will clean my microweave in return.

Edit: It's a Mica cover. TIL.

Ceramic or mica waveguide cover. Do not use the microwave without replacing it, it stops radiation getting in the electronics and blowing them up.

    Mica cover does not stop radiation whatsoever. It stops boiling grease from your overheated sausage from drizzling onto the electronics.

    It's still a bad idea to use a microwave without a mica cover, it's gonna stink with burning grease after a few uses.

    Most microwaves do not have waveguide nowadays, the magnetron sits right behind the mica cover.
