HI Dirk
when you say you have two of each, do you mean two multicoloured candle holders, two just blue with chlorides and then two vases? or do you just have the blue with chlorides candle holders and the vases?
I'm just trying to work out that when you say from the same maker, do you mean all the pieces, or just that the blue with chlorides ball candle holder and the vases are the same maker, leaving aside the multi coloured ball candle holders?
Sorry to be so pedantic, but I just wanted to be clear which pieces Mr Hoffman had said was Gral Glas.
Then, when you say they are all from the same maker do you mean all the pieces , i.e. the multi coloured ball candle holders Anik has, and the blue with chlorides ball candle holder and the vases as well?
apologies again, but I just want to make sure I've understood correctly

So it seems from the UV experiment that the clear glass casing on all these pieces does not match the clear glass casing from your Gral Glas pieces. Is that possibly explainable because they are from a different period in the factory's life so they might have been using a different batch for the clear glass? or might it only be explained by the fact they come from a different factory?
that is the question.
