So here is a new mystery. At first glance one might think this a juicer of some sort, however I am not convinced. I personally have never seen a smooth sided juicer, though I am told they are available to reduce pulp. However there are 2 valleys in the side where the juice would just run out, no where to collect and pour.
This piece is about 4 inches in diameter, and while trying to clean it i discovered the orange will actually rub off the glass.
So..... what is it? All guesses welcome! By the way, the kids aren't around, so have at it ;)
