Hi Keith, I will not be so rude as to "shoot you down". :thup:
The comment that I would make regarding the piece is that although the piece has some light ribbing, applied leaves, and is mold blown and ground on the lip, reminiscent of some Kralik work (and also many others including English).... the primary thing that leads me in a different direction is the use of graduated opalescence in the body of the vase. They also did leaves, just not quite this folded, at least that I have seen. Typically, the Kralik work using opalescence in the piece will have a pretty consistent opalescence throughout the body of the vessel. That is not to say that it is always a real milky opalescence, just that the color is consistent. I have an early vase in my collection which is by them, and it has a light opalescent body similar to the upper portion of this piece, but it is basically the same at the top and bottom of the body. I can not think of having seen a Kralik piece with this type of graduation. My guess is that would also be what Alfredo sees in the piece.
Lastly I would say that almost all of the work on identifying Kralik (and others) is based on empirical study since no accessible records exist for the company. Marcus did point out that here is material sealed in archives by the Czech Republic and will not be accessible until around 2090. As a result of the empirical study, the discovery of a single piece of marked or identifiable glass could change many of the currently accepted concepts regarding Kralik.
Personally, I am sticking with possibly English for this piece...... but I would not rule out another Bohemian company either.... Just not Loetz, Kralik Pallme-Koenig or Rindskopf.....
