It is 7 inches across and 6 1/2 inches top to bottom. 1 3/4 inches deep.
I think it was used as a soap dish, and has a little lime-like substance. It should come off, but I didn't know exactly what to use. There is a line in the glass as shown in picture 5 and two little smooth nubs of extra glass on the scallop as shown in picture 4.
