This page lists the company numbers that participated in Veneziavetro, a consortium promoting Murano glass since the 1980s. Please note that not all glassmakers were involved. For example, you will never find one of these labels on pieces by FontanaArte or Vistosi. These companies sometimes used labels mentioning Murano, but not the official Vetri Murano numbers.

Over time, some lighting manufacturers worked with different Murano glass suppliers. For instance, you may come across Kalmar lamps with an 014 label (from AV Mazzega) and others with an 048 label (from Leucos). However, an 048 label does not automatically mean your lamp is by Kalmar or Leucos – it could just as easily be Artemide or Arteluce. The key is always the lamp itself: its design, style, and period. In this case, the glassmaker for these companies was Leucos.

The same situation occurs with 012, where multiple company names are linked, but the actual glassmaker was Aureliano Toso. In some cases, the manufacturer is harder to identify, as numbers appear to have been shared.

Originally, the numbers consisted of two digits. Later, a zero was added at the front (e.g. 44 became 044), but the companies themselves remained the same.

I have not included images of the labels here. Apart from the number, the labels all look the same. They are already shown in the Labels & Logos section, and adding them again would not add much value – it would only slow down this page. I also do not know exactly how long the sequence continues; the last one I have recorded is 57.

The Vetri Murano labels were used until the early 2000s. In 2002, new colored labels were introduced; these are listed on the right for completeness. Since 2016, labels with QR codes have been in use.

At the bottom of this page you will find links to Facebook groups and websites with more information about Murano glass labels. These resources are especially useful if you are researching glass objects, rather than lighting.

If you have additional information or answers to the open questions, please get in touch via the contact form. Thank you!
