Is this Murano Glass authentic?
When I was in Murano, I visited a glass factory and told me to look for the “authentic Murano/Venetian glass” sticker on pieces to make sure they weren’t street-vendor knockoffs. I don’t know if this is the case everywhere, but the nicer pieces on the island seemed all to have the magical sticker while a curiousity-check of some street vendors revealed stickerless glass. This may not be helpful at all if the tradition is restricted to Murano itself, however.
