This is a Venice Clay amphora / Arts and Craft style vase.

 It measures 9 1/4" tall.

 It is stamped on its base, but it's difficult to read because it's smudged: Venice Clay Handmade USA., along with a G. Steinborn signature in a different ink.

 The glaze color is Blue Fog. 

The exterior of the vase is in very good, clean condition. The interior of the vase has light residue from use. Visible in the photo of its interior.
