Little kids as young as 12 years old are joining their fathers and grandfathers in the furnace to help them and learn the art of glass blowing. Thus, the ancient secrets and valuable knowledge cannot get in the wrong hands.

What is Murano Glass?

When people talk about Italian art glass or Venetian art glass, they are usually referring to the sculptures, vases, chandeliers and decorative glass objects made in the island of Murano, Italy. Murano is a small island in the lagoon of Venice, where the art of glassmaking has more than 1000 years of tradition. Only glassworks made in the island of Murano can be marketed as Murano glass artworks.

Unfortunately, there are many counterfeit Murano glassworks on the market. These glassworks were not produced in the island of Murano, yet they are marketed as ‘Murano Style’ glassworks to deceive customers. The good news is that once you know the main characteristics of genuine Murano glass, you will be able to judge if the artwork is real or not.

7 Things That Affect Murano Glass Prices

1. Look for imperfections

Real Murano glass is handmade, which inherently results in small imperfections. Such imperfections could be for example air bubbles or the Pontil mark:

A. Air bubbles

When the multi-color layering technique is used, the glass master blows the different colored glass separately and then layers them on top of each other. During this process, it is inevitable that small air bubbles are created. In order to avoid bubbles and have clear glass, in locations far from Venice and Italy they use the Lead in the composition. This is a dangerous metal that is not part of the Murano Glass tradition. Using Lead is forbidden in Murano and a crystal which is not 100% clear, is a true sign of authenticity.

B. Pontil mark

Another small imperfection is the Pontil mark. The Pontil mark is a scar that was left behind when the glass master broke the Pontil rod of the finished blown Murano glasswork. The Pontil mark can be found on the bottom of a hand-blown artwork. Touch it with your finger and you can feel that the surface of the Pontil mark is not smooth.

2. Look for proof of origin

Remember that genuine Murano glassworks are only produced in the island of Murano, Italy. Murano is not a brand name, it is a physical location. Based on the signature of the glass master and/or certificate of authenticity you can identify the origin of the glasswork.

A. Signature of the Murano glass master

Look for the signature of the glass master on the artwork. Then go online and check if the glass master is indeed located in Murano, Italy. Furthermore, to make sure that the signature is original, compare it with the signature of the glass master displayed online.
