Vintage Hand Blown Glass Emerald Green 10" Vase - Likely Blenko Or Murano This vintage hand blown glass vase is in excellent condition with no chips, cracks, or any sort of flaw. It is a beautiful emerald green color (with lots of bubbles in the glass) that is almost always recognized as Blenko, but this piece is not marked, so im not sure if it is just a really good match. If it wasn't made by Blenko, it was likely made in the Murano or Empoli regions of Italy by a local art glass maker. Measures approximately 10" inches tall and 7" inches wide at the widest point.
