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.

See the comment under mine for the correct answer(microwave cover).
If you find the model number on the tag, you should be able to order a replacement cover from somewhere like Amazon or similar.
It’s not, it’s a ceramic microwave cover
