Both of the Kralik attributions on CW are actually based on vapor. The one directly above is based on a "feeling", and the pair are based on the link and some additional bad information.
This decor has never been linked to Kralik for sure, at least that I am aware of. This decor has been discussed for quite some time with no resolution, but lots of guessing and unfounded attributions.
Here is something I have been working on in regards to this surface pattern, which is seen a bit, but not all that common.
Let me say at this point that I am not saying who these are by yet, but I would say that the decor is generally seen on shapes which can not be specifically assigned to any house. There is of course also the possibility that at least a couple of houses did this style of surface texture.
The first image below is of two vases in a pretty distinctive form which I have determined to be Welz production.
The second image below is of a pair of vases in a very unique decor which exhibits the maze style surface decor. More difficult to see with this decor, but there. The shape, ground, and pattern are all fairly unique.
The third image is of a larger example of the decor and pattern on a vase which has never really been identified as to maker, and there are a few others in this distinctive decor and surface. None of these have previously been linked to any house for sure.
The 4th image shows the base of the third image.
To say the least, this would at least seem to indicate that there is the possibility that Welz may have been one of the houses producing this surface decor. The ground in both images 2 and 3 would also seem to possibly fall in line with what appears to be their "Artistic Individuality".
Just some food for thought.... and a possible lead as to the maker, or at least one of the makers.
