Any information on this large glass vase , it looks to have been hand made,you can feel the different layers of coloured glass, while the top is speckled and smooth the base looks to have been applied afterwards, on the base there is a pressed stamp which looks like a castle maybe with a key below, there is an etched mark also PA 1998, the vase stands 11.5" tall and weighs 1.25kgs



thanks roy
