@cliffordbeshers It’s a food container being washed (or just have been). And it’s dishwasher safe.
@cliffordbeshers Oh, is it the lid on a frying pan or a casserole, (and you’re frying/cooking something)?
@odd No, you were right with the food container. That’s the lid, and when I put it on the container, it was dry.
@cliffordbeshers Oh, so you’ve had it in the fridge or freezer, and the damp from the warm food evaporated and cooled and now shows up on the lid?
@cliffordbeshers I was going to suggest that it's Webb Space Telescope photos of the PartyTime Nebula.
