My first piece of glass(back in 1980 or so) was a nice little Latticino vine leaf. I could not find out anything about it so I took it to the art Gallery of Victoria(Australia) where I live and was told it was a modern copy of earlier Murano. The reason it was modern is that it is very thin, say about 1mm. They pointed out that old pieces tended to be thicker as the earlier glass was less runny and thus could not be drawn out so easily. Whatever, it is a spectacularly, lovely piece and congatulations on such an excellent purchase price. Just call me Mr Green in the home office
