Nothing to excuse you for Ivo.
You have your references, and I have my observations. I would be quite curious as to the reference(s) you are referring to that led you to a PK attribution on this piece.... I am always willing to learn, and if I have missed something, I would be remiss if I did not ask you to direct me towards the information that would have led me, like you, in a different direction on this attribution.
I did, quite clearly I thought, state it was my humble opinion.... and last I checked, I was entitled to one based on my observations and personal research..... There is nothing in Truitt Vol I or Vol II that is like the piece and linked to PK, and most examples in that book are like what I actually understand PK production to be. I would have to mention that the "benchmark threaded" piece they show as a first example for PK in Vol I, is in fact, a Kralik production item. (There is that darn error in a book thing I was talking about) There is also nothing else in any other publication I have seen that attributed similar production to PK. Written information on PK and Kralik is quite sparse as far as I have found, hence my interest in studying the glass as much as I have. I can also not find any examples on the internet that are similar PK production. Threading on PK pieces, yes, but nothing with this style of glass treatment and shape.
Additionally, I would have to point out, the records under lock and key until 2090 for Kralik are not records that cover this time frame of production (according to the archive records for years covered by the data), so even if they could be accessed, empirical data is all that would be available for identification of this piece anyway. Other than Loetz, the largest percentage of written material on this subject (Kralik and PK) is as a result of empirical study.
I never stated at any time I was an expert, and writing a book would certainly not make me one. Hermann Spaink proved that beyond a shadow of a doubt with his book on Tango.
For what it is worth, I obviously have a different opinion than you on the origins of this vase. That seems to have offended you in some manner, setting forth the tone of sarcasm I sensed in your first response and your follow up comment. I am also, for what it is worth, quite comfortable and confident in my opinion that it is not a piece of PK production. You are certainly not obligated to agree with me.
I get the distinct impression that because I have not put something in writing (a book), you feel that my observations should be questioned more intensely at this point. Honestly, I am OK with that. I question many opinions on here at times.
But, if you choose to dismiss and question my observations with the public tone of sarcasm I am sensing, then please politely provide me, also publicly, with the reference materials you are basing your attribution on. I would love to see them, as I have been unable, in the last several years of studying this glass, to locate them. I look anxiously forward to getting copies to review.
