I usually look in your book, Creative Energies before googling. Maybe missed it but there it is.
It does get confusing when glass companies are named after towns, especially when they are not located in that town.
I see that Transjo Hytta AB is located in the town of Kosta.
Googling some more this description seems to give a more enlightening picture of the area and Transjo Hytta's place in it.
"Connecting Växjö and Kalmar is Glass Country, a 70-mile stretch of forest sparkling with glassworks. Frankly, these glassworks would hardly raise a rattle elsewhere, but they gleam in Sweden's calm countryside air.
Of the several renowned glassworks in the area, Orrefors is the most famous and Kosta is the oldest, dating back to 1742. Both are set up to appease the masses, offering tours, daily glassblowing action, easy shipping, and nearly perfect crystal seconds at shattering discounts. The tiny Transjö Glashytta offers a much different experience — expensive but fine art pieces created on an old converted farm." http://www.ricksteves.com/plan/destinations/scan/ruralsweden.htm
It seems they have been very active in training up and comming glass artists but I haven't found a website for the company as yet.
