Thanks all for the comments!
I have the advantage of running into Karcag pieces quite regularly here in Vienna, no wonder with the border to Hungary so near.
There are always some Hungarian sellers at the fleamarkets, selling mostly ceramics (which I love, and have a few in my collection).
Usually, I do not buy Karcag glass, but I fell in love with the colour of this ashtray

m, unfortunately I don't know anything about the output of Karcag apart from these "veil glass" pieces...
