Ivo...noted & possible. I assume that statement holds true for european vase blanks & incorrectly did not consider that point dealing with a european blank since many of our finer glass companies in the Corning NY area did not feel this way as many blanks from multiple finer hand blown operations, Steuben, Sinclaire, etc. produced vase blanks featuring ground pontils with straight tops...sans ruffles & flairs. Evidently our companies didn't follow the european design approach.
