Below is a list of numerical codes found on the Vetro Artistico Murano labels, along with the corresponding Murano factories that they relate to. The Vetro Artistico Murano labels bear a logo of a "borsella" (glass working tool) making a plate, on a white or clear background, and are made up of segments that come apart easily if removal of the labels is attempted. These labels are managed and publicised by the Promovetro Murano Consortium, which was founded in 1985, as a method of protection and certification for authentic Murano glass factories. The Vetro Artistico Murano trademark was instituted into law in 1994, and the labels themselves have been in use since 2002. They come with either a white opaque background, or clear transparent background, and since 2016 a QR code has been added. The information below comes from the current list of factories at muranoglass.com, a slightly outdated pdf list found online, and labelled examples found online or shared by members of several Murano glass study groups based on Facebook.
Update - I recently came across an article published on another site about these labels, with a list almost identical to ours, but with a few extra's added. The site is known to be accurate with other Murano information, so I will add these extra entries to our list, and highlight them in pale grey until I am able to verify them with labelled examples.
