I am very keen to find out the origin of this beautiful vase which I bought as a Murano vase at auction. It stands 29.5 cm high and weighs an incredible 4.6 kg. As can be seen, the base is solid glass, made separately then attached, and the vase itself is also very solid. The various techniques used are apparent from the photos. I would love to know the name of the glassmaker, approximate date and the name of the glassworks. Any of the above would be greatly appreciated.
