Bought this from the local charity shop near work for a couple of dollars. 7.5cm tall brown/amber sommerso ewer. Oddly, it has water staining in it. Why would you use something so small. The clear glass has a yellow green/blue'ish tint to it but it doesn't really show up in the pics. Have tried a black light and it is not UV reactive (unless the black light is a dud). Any idea on country of origin? I was thinking murano of course but scandi could be an option.
