Crackle Glass Hat Vase. The reason I call it a hat vase, if you display it by flipping it over, it looks just like a ten gall hat, and it can be displayed this way, if you choose. However, it makes a beautiful center piece vase. The vase is as wide as it is tall. It is 9 1/4" tall and 9 1/4" x 9 1/4" wide. It has a hand applied light blue glass trim to the rim of the glass. The entire vase is beautifully crackled. Shapr pontil scar created from being hand blown. This particular piece was made by the Blenko Glass Company, circa 1950's.
