vintage teal green spatter glass vase, mid-century Murano glass or Blenko?

Unmarked vintage hand blown spatter glass vase in a beautiful teal green color. It's in excellent condition without damage. Stands about 6" tall.

We've been told this is a Blenko (or possibly Kanawha?) piece, though it looks more like Italian art glass to me. I haven't seen spatter glass from West Virginia glass makers before!
