Glassmakers' Guild parades and processions.
I'm referring to somewhat older times, although these still do go on.
I'm not sure whether or not they were sold.
I do have a wee story about one though. :thup:
I know a chap who used to work for Phoenix glass here in the uk. He told me that somebody there had made a fabulous and massive frigger of the ship "Bismark". It was put into the annealing oven to cool - but when they went back for it.... it had vanished.
Nobody knows what happened to it.
So if anybody encounters a massive and fabulous frigger of the Bismark, it's from the Phoenix glassworks but - watch out - it's stolen property!
