I can't comment on the two KM vases you have. I can comment on the ones in my collection and I can comment on the 120 I bought for my cafe. In the later case they were all great but since that some was some years ago I can't comment on the quality of KM glass of current production other then what i've dealt with personally.
As my managing a glass production facility i'd say it went pretty well since it got an export accommodation for quality control.
i honestly dont see why one would weld brass, i see references to it on line but i dont see how it works out since the zinc will burn off when heated hot enough to melt the brass. brazing would require a lot of clean up on brass too since again the zinc burns off and you get a copper plating, most of the hookahs use cheap plumbing/low temp solder
Well gee, in the case of Syrian crystal I got to go into work shops and see the welding take place. I didn't second guess them about why they did it the way they did it and at the time I was distracted with the drawing opperation so I didn't inquiry about the specific method used. Still, my Syrians have great looking joints and they stood up well to many years of service so that strikes me as great quality.
