Hello, any advice on this piece of glass I have purchased please. It looks scandinavian,and very much like an ariel piece. It certainly had a lot of work, by a skilled artist to make it. It is 5 3/4" tall & 5" diam. at the top. It is cobalt blue glass, with some grey & lighter blue added. It has been ground before being blown, and each ground area has been pricked to leave an air bubble. It has had a cobalt blue strap laid around the top rim,and has a clear base, with tiny air bubbles throughout. It has a flat base with concave ground pontil. There is no writing, or printing on it. It is a lovely item, which is why I bought it, but would love to know who made it, etc. Regards, John. :huh:
