I came across this vase in Northern Virginia in the states.
The clear glass has a subtle aquamarine hint with a relatively thick (+/- 1/4") wall. The offhand piece shows some similarities to Blenko pieces, but I haven't seen this form or color.
I'll try to take a pic of the base, first round wasn't very clear. Has a 1 3/8" circular unfinished pontil mark with some fine hand grind marks to smooth edges.
Recycled glass from Mexico, Spain? 70's, relatively contemporary or brand new?
