I make water pipes using vases from goodwill, and one day I found this. One downstem later, and It's my go-to bong, and rips like a demon. I call it "lapis" I believe this was made in Venice, and would love a glass guru to help confirm this. The ashtrays behind it ARE murano glass, and I just got them at a yard sale for 5 bucks (which is a fraction of their worth.) my concern is that, after learning about murano glass, I've ruined a $40-100 vase. Any thoughts?
