Transjo Hytta - Sweden - 18" Glass Vase

I picked this up in a gallery in Stockholm in 2009. I knew nothing about the artist, but they were kind enough to provide me a brochure (in English) highlighting Transjo Hytta based in Kosta, Sweden and their primary artists (Sven Ake Carlsson and Jan Erik Ritzman - both formerly employed by Kosta Boda). At the gallery, I was actually torn between this piece and a less expensive piece of Kosta Boda glass, and the clever sales clerk insisted that this was the more original of the two and a more unique addition to my collection (it wouldn't hurt his commission either). But I followed the logic and paid more for this piece than I had any other glass piece in my collection at that time.

I do not regret it. It is so large (18" tall) that it sits on the top of one of my bookcases, all alone, looking quite regal. The purple color is beautiful, and the wavy/line design blown into it makes in visually interesting to stare at. I looked for other pieces by this studio - since there appears to be a lot of Scandinavian glass on CW - but I haven't seen any others. Is this a well known studio in Sweden?
