Accidental shot glass
This was supposed to be a 1/2-cup measuring cup for my dog's food. When I did my math, I used the radius when I meant to use the diameter, so it's only about a quarter the size it's supposed to be. Conveniently, it's just about right for a shot glass, so whatever!
The glaze is all white. I put it on a little too thick so it cracked and fell off around the top lip, but it's vitrified so it's still functional.
