A Look At Interwar Decors and Shapes

-The yellow and pale blue spatter decor, shared by several Czech interwar producers


















One of our Czech collector member, has the habit of claiming that if a decor is on one of his *'Welz' shaped pieces (*his attributions), every order glass piece with a similar decor is also 'Welz'. No Question. These conclusions are usually based on images of spatter application decors, not actual study of the glass. So you have all the pit falls of different camera settings, different conditions, different skill levels, etc.


My opinion was that the specific example #1 was a Kralik product, part of a family of pitcher or jugs usually in the Tango style, but this one was in this yellow and blue spatter on clear. My statement was dismissed as the jug had no pontil, and this was not a Kralik product for that reason according to the 'Welz' collector. Since I have a large portion of Kralik pieces in my collection, his statement made no sense


Another collector had documentation to show a basket with the same decor, in the Harrach cabinet, at the Passau glass museum, several photographs with clear identification as Harrach.


Of course, Mr. 'Welz' denied these facts as well, calling them a mistake made by several Czech and Bohemian glass experts in Europe and America, something that does happen, but not frequently, at a respected Glass Museum level, especially for Harrach glass, who is well documented, and known. 


I am providing more images which are considered the same decor, but when you see them all together on the same page, does not look quite right. My criteria for judging a glass spatter is a close look at the combined colors, in daylight. By using a flash, you can totally transform the glass piece with the harsh light. One of the pit falls that I was talking about. 


If the colors used completely match, that is a good sign, how they were applied is not as important, as it is a hand crafted step of rolling the vase onto a maver surface with chips of glass spread over it. The items would be produced by the same maker.


If the colors have variations, in shade, hue, or the addition of more colors, or the cased glass interior has an opaque color, this will also point to another producer, of course, the shape matters as well. An identified shape by consensus, may be a determining factor. Pontils or not, do not. The examples below do not qualify as the same decor, hence diferent producer, Kralik #1 again.
