​​​​​​​ANTONIN RÜCKL & SONS 1919-1939

Including WILHELM KRALIK & SONS Czech Glass

These are the two lidded jars in question, left is A and right is B, both have pointed finials and an orange glass background with a loose multi color spatter on lid and base, but not the exact same tones or shades on both pieces. For this exercise that does not matter, as the shapes will identify the pieces, and the other decors found on the same shapes which are already identified as Kralik and marked as Kralik. You may want to look at my page CzechGlass-I in the middle section, where I show some Kralik vases with bottom spatter decors, since there were many produced.


​The other two combination images shown above show jar B with three other decors, which are definitely Kralik. The second image shows both jars and a series of Kralik vases in between in the same glass color range decorative mix.


The biggest issue for some is the label on the jar A. There is a Royal Art Glass label, which was attributed to another glass house in the German GlasMarken Lexicon, a large reference book publication that is considered an excellent work of good repute regarding International vintage and antique glass marks, especially European.

Since it's publication, and the intense focus on F. Welz by a few, and the marks and labels attributed to them, one being this RAG mark on a label, we have found at least 12 different Czech glass pieces from the same period with this label applied to it. As more glass pieces are found, this label is now considered by many as a distributor label, found on several glass company's products and shipped by the same exporter/distribution company. Did the lexicon make an error, it depends how you look at it and what their criteria was based on, and how much information was available to them. One result is assured, you can no longer use this label to attribute the glass to the Franz Welz company.


I will write an article about this study and results which took five years and several collector's efforts to accumulate data and come to this conclusion.


To continue with this study I am adding 3 more examples of the Jar A shape, with 2 decors which are definitely attributable to Kralik. The black millefiori decor, and the red with white and blue/black spatter, both in shapes that are signed with a Kralik mark. The jar in blue and red mottled decor and iridescent finish is a rarer decor, still interesting to see and add here. More Kralik glass pieces are added on the bottom of this page which are related to the original topic of the two jars A & B either in decor or shape with a Kralik mark.

Butler Brothers Ads - Confusion why   glass item selections provide an ID


There seems to be some confusion about the information I provided on this site for the last 3.5 years and my grateful use of the Monograph published by the West Virginia American Glass Museum, in Weston Virginia. Compiled in 2012 by the multi tasking and busy founder Tom Felt. There is one BB ad I have not used here on the site at all, or discussed, because in my opinion it contains glass from several production houses, some of which is not within my site's purview. 


One glass collector in particular, keeps comparing, what I say here on another site, with his own sources of information, regarding the Franz Welz Klostergrab business enterprises, including coal, glass and other categories. The main problem is the mixing together of two vastly different time periods, the mid to end of the 19th century, and the 20th century interwar period of 1920-40. Attributions for this company go from one end of their existence to the other, pointing out documentation available before WWI, and applying them from 1920 and later. This is where the wholesale of glass exports from Czechoslovakia comes in, with the glass ads. There is absolutely no proof that Welz produced glass then, this is documented in the Truitt's Volume II. They may have had another role, such as distributors, as the Royal Art Glass label was finally proved to be the case. The ad below may all be by Kralik, or at least half of it is. They may be marked by a different type of font, that should not be used as an identification of a maker, but of a distributor.



We are helped in this endeavor by the huge number of glass exports made by Kralik, and the fact that Kralik used the same decors on many shapes and vice versa. They also had multiple plants, different marks, and could do glass decor and shape variations that seem endless in their numbers. Before you identify a piece of Czech glass, make sure you are not in the Kralik ballpark, because it's boundaries are still unlimited. My own Ruckl glass research has evolved with this in mind, as they are the main competitor in this specific field. I will start with a current series of glass jars that seem to be in limbo between Kralik and Welz on a collector site. They are Kralik and I will show why.

MoreCzech - KRALIK GLASS I


This page is the first in a series to help with the identification of W. Kralik decorative glass exports, produced during the same interwar period, yet not identified anywhere else.  I am including several USA Butler Brothers wholesale calalog images which pertain to Kralik pieces, as most Bohemian - Czechoslovakia decorative glass were by Kralik, ads that were placed between 1928 and 1931. These will help you see the variety and style of this company's Art Deco Czech glass and help you with their unmistakable identification. Labels or not.
