glassroots hyacinth vase

I found this on ebay recently and recognised it as a glassroots hyacinth vase although it is unmarked. I feel sure it is glassroots as the shape, weight and even the water staining which the glassroots vases seem to suffer from is so distinctive of the glassroots vases. I also have a lime green one unsigned of this shorter vase and a cranberry signed glassroots taller vase. Will photograph them all together.
