Hi, I have a 7" tall bulbous cluthra vase with a wide flat rim that has been cased in clear glass. It doesn't have a pontil, which eliminates some of the most obvious potential glassmakers. The initial gather appears to have been pink with large white pieces of glass marvered in, then rolled in pink colored powders with chemicals to produce the bubbles, so the interior (including the top of the rim that was pulled down) shows a lot of white while the exterior shows primarily pink. There are lots of bubbles throughout the vase, but none get really big like some of Steuben's cluthra.
I am assuming it is a relatively modern vase, but if so, I don't have a clue where vases like this might have been made.
Any ideas where this could have come from? Thanks much!
