Hi there,
Would it be possible to see images of the top edge at the mouth of the vase, and also the underside? If no images, is the mouth fired or ground. Underside... pontil, cased with clear, ground? What about age wear?.. Or do you have any idea of age? What is the size of the piece? Pictures would be great..... It is a nice looking piece of glass...... Strikes me as Czech, but I'll reserve the opinion pending additional images or information.
