This is a 9" vase in the more unusual amber uranium glass. I am very inclined to say that this is a Murano piece mostly because of the rough snapped pontil which I associate with Murano glass. A name that has cropped up in research is Vittorio Zecchin who worked for Venini and others in the 1920's-30's but at the moment that is speculation. I've seen amber pieces by him named as "Opalina" which might indicate uranium. Any thoughts welcome.
