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.

It’s an important shield thing, you should replace it with a new one. When ours failed it caused the microwave to start to do very loud and distressing electrical arc zapping sounds inside.
