4" 10-12 oz. There is a small cobalt smudge on the handle. Cobalt, is the mineral that creates the bright blue seen on ceramics from all around the world. It is always...(well almost always) Blue.
It is a strong colorant, doesnt take much... so when working with it, we can get it on our fingers and not realize it, hence the small smudge, it doesnt show until the firing.
