My rating: 8/10

Length of visit: 1 hour

Even the most distracted tourist, strolling through Venice, cannot fail to notice the sheer number of shops selling handcrafted glass objects—sometimes a little kitsch and rough, other times exquisitely made. The reason for the widespread presence of this offer lies on the island of Murano, one of the islands of the Venetian lagoon just a few minutes from Venice, where a glassmaking tradition has been established for centuries.

To speak about the glassmakers of Murano means to address one of the rare cases in which an entire island has built its economic, social, and cultural identity around a single activity, transforming it into art, industry, myth, and—inevitably—a global brand. Murano is not merely the place where “glass is made”: it is a productive ecosystem layered over centuries, governed by laws, technical secrets, family rivalries, and a continuity of knowledge with no true equivalent elsewhere in Europe.

In this post, I will recount the history of Murano glassmakers, the main types of glass and artifacts, the concrete experience of visiting a furnace, and some practical advice on how to distinguish authentic production from tourist caricature.

Murano, the glassmakers, and Venice: a strategic separation

The island of Murano is inextricably linked to the history of Venice, but its fortune stems from an eminently political decision. In 1291, the Venetian Great Council decreed that all glass furnaces be moved out of the historic center, officially to reduce the risk of fires in a city largely built of wood. In reality, the motivations were more complex: concentrating glassmakers in a controllable location meant protecting production secrets while simultaneously monitoring a category that was strategic to the economy of the Serenissima.

From that moment on, Murano became a sort of “industrial district ante litteram,” isolated yet privileged. Glassmakers enjoyed exceptional rights: they were allowed to carry swords, were exempt from certain taxes, and their daughters could marry members of the Venetian nobility without losing status. In exchange, they were bound not to leave the island. The escape of a master glassmaker was considered industrial treason and prosecuted as such.

The Murano glassmaker: artisan, technician, alchemist

The figure of the Murano glassmaker does not coincide with the romantic image of the solitary artist. Historically, glass production has always been collective work, organized into teams with rigidly defined roles: the master, the assistants, the apprentices—each responsible for a specific phase of the process.

Knowledge was not codified in manuals but transmitted orally, through observation and practice. This produced two decisive consequences: on the one hand, an extraordinary technical continuity; on the other, a strong corporate closure that made Murano impermeable to external innovations for centuries, yet also capable of refining its techniques to an extreme degree.

The Murano glassmaker has always been, in the strict sense, a materials technician: knowledgeable about the proportions of silica sands, melting times, the reactions of oxidizing metals, and the behavior of glass at different temperatures. The artistic element arose from absolute mastery of these factors, not from abstract aesthetics.

The great inventions of Murano glass

Murano did not merely produce glass: it invented typologies that shaped the history of European decorative arts. These include cristallo muranese, an exceptionally pure and transparent glass, free from the greenish hues typical of medieval glass, invented in Murano in the 15th century and which made the island the leading supplier of luxury objects to European courts; lattimo glass, opaque white and porcelain-like, developed as a Western response to the importation of Eastern wares; filigree glass, achieved by embedding white or colored glass threads within a transparent mass to create geometric patterns of extraordinary precision; reticello, composed of two sets of interwoven glass canes forming a three-dimensional lattice with tiny air bubbles at the intersections, achievable only through perfect thermal control; and finally murrine, cross-sections of multicolored glass canes which, when cut, reveal floral or geometric designs.

The products: from functional objects to sculptural works

Historically, Murano production was predominantly functional: tumblers, goblets, mirrors, lamps. Objects were meant to be beautiful, but also usable. From the twentieth century onward—especially after the Venice Biennale and Murano’s encounter with international design—the focus gradually shifted toward sculpture and the artistic object.

Today, three broad categories coexist:

• Traditional objects: goblets, vases, chandeliers, mirrors, made using historical techniques.

• Contemporary decorative production: objects conceived for interior design, often serial but still handmade.

• Unique works of art: signed sculptures, often resulting from collaborations between master glassmakers and artists or designers.

It is important to stress that value does not automatically coincide with formal complexity: a small, perfectly executed blown-crystal goblet may be technically more refined than a large, visually striking sculpture.

Visiting a furnace: what to really expect

Entering a Murano workshop is a compelling experience. The heat is intense, the noise constant, the air dense. Molten glass allows no mistakes: every gesture is final, every hesitation results in waste.

Visits to workshops, including demonstrations of the creation of a small object, are clearly tourist-oriented, but this does not detract from the fascination of the performance. Demonstrations take place throughout the day, typically every half hour. Visitors are welcomed at the entrance of the glassworks and organized into groups. In some furnaces, the demonstration is viewed from tiered seating set up in front of the furnaces, which in my opinion diminishes the sense of immediacy and intimacy; in others, the environment is more compact, which enhances spontaneity and audience engagement.

During my visit to Murano, I visited two glassworks: Ellegi Glass and Vetreria Colleoni. I found the former rather disappointing—the demonstration lasted about ten minutes, visitors were crowded onto the bleachers, and the overall impression was overtly commercial. The demonstration at Vetreria Colleoni, by contrast, was decidedly more engaging: longer duration, closer proximity to the glassmakers, more detailed explanations, and a stronger sense of passion in conveying the history and specificities of this craft.

The typical visitor demonstration shows the essential phases of glassblowing. It is an authentic spectacle, but a partial one: many of the more complex techniques—filigree, murrine, reticello—require timeframes incompatible with tourist visits.

A good indicator of quality is the presence of the master glassmaker at work, rather than mere demonstrators. Another revealing element is a limited number of pieces on display: serious furnaces are not bazaars, but places of production.

Authentic or souvenir? How not to be misled

One of Murano’s structural problems is competition from counterfeits, often industrially produced abroad and sold as “Murano style.” A few practical criteria can help you find your way:

• Price: authentic Murano glass is never cheap. Be wary of complex objects sold for just a few euros.

• Certification: the Vetro Artistico Murano trademark guarantees origin, but not automatically artistic quality.

• Imperfections: small asymmetries, bubbles, and chromatic variations are signs of handmade production, not flaws.

• Vendor transparency: those who genuinely produce their work are able to explain techniques, timing, and the limits of their craft.

Buying in Murano does not simply mean purchasing an object, but supporting an artisanal supply chain that has been under pressure for decades.

Practical advice for visiting

• Dedicate at least half a day to Murano: the island is not only furnaces, but also museums, churches, and less touristy areas.

• Avoid “all-inclusive” organized tours: they often funnel visitors into low-level, affiliated furnaces.

• Talk to the glassmakers: even a brief conversation reveals the difference between those who produce and those who merely resell.

• Visit the Glass Museum: it helps contextualize techniques and styles, making any purchase more informed.

• Do not rush to buy: observe, compare, and, if necessary, come back the following day.

Murano today: between excellence and fragility

Murano lives in a constant tension between tradition and economic sustainability. The number of active furnaces has drastically declined compared to the past; energy costs and global competition make the profession increasingly complex. Yet it is precisely this difficulty that has pushed many masters to focus on extreme quality, uniqueness, and collaboration with contemporary art.

Visiting Murano with awareness means not seeking the “iconic object,” but understanding a fragile and precious productive system. Glass here is not a simple material: it is solidified memory, human labor made visible, time transformed into form.

And perhaps this is the island’s true lesson: beauty is not born from speed, but from skill, tradition, repetition, and error corrected in fire.
