The expensive part of ordering a custom "ADA" jar from a local glass fabricator is the beveled edges I think. The beveling requires lots of work and a BIG sanding machines. Thick low iron glass + beveling + extra delicate and time consuming silicone work = expensive. At least it is here in Sweden.
ADA Germany is apperantly back from vacation and my mail will go them through my local ADA dealer. Now I just hope they and ADA Japan can read english good enough, added lots of pictures just in case. :/
