I was very surprised to walk into the local St. Vincent de Paul shop to find this beautiful console bowl with the Corn Flower cutting. I have never seen, in the wild, a piece cut with Corn Flower in any colour other than pink, hawthorne (Heisey) or the pilseners with the red bases. Definitely never the green.
I don’t know the glass maker. A photo of this piece shows up in Walter T. Lemiski’s book Elegant Glass with Corn Flower but does not indicate the provenance.
