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 5 or 6 different Czech glass pieces from the same period with it on including some Welz glass, yet the glass is not all Welz, or if it is, nobody has been able to prove it. I think the contrary is coming true, as more glass pieces are found, this label is more likely one that was a distributor label, found on several glass companies with 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.

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.

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.


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.
