Venetian glass is glassware made in Venice, typically on the island of Murano near the city. Traditionally it is made with a soda–lime "metal" and is typically elaborately decorated, with various "hot" glass-forming techniques, as well as gilding, enamel, or engraving. Production has been concentrated on the Venetian island of Murano since the 13th century. Today Murano is known for its art glass, but it has a long history of innovations in glassmaking in addition to its artistic fame—and was Europe's major center for luxury glass from the High Middle Ages to the Italian Renaissance. During the 15th century, Murano glassmakers created cristallo—which was almost transparent and considered the finest glass in the world. Murano glassmakers also developed a white-colored glass (milk glass called lattimo) that looked like porcelain. They later became Europe's finest makers of mirrors.[1]
During the Early Middle Ages, Venice was originally controlled by the Eastern Roman Empire before eventually becoming an independent city state. It flourished as a trading center and seaport in the High Middle Ages. Its connections with the Middle East helped its glassmakers gain additional skills, as glassmaking was more advanced in areas such as Syria and Egypt. Although Venetian glassmaking in factories existed as far back as the eighth century, it became concentrated in Murano by law beginning in 1291, in part because glass factories often caught fire, and moving all of them to one island removed much of the possibility of a major fire disaster for the rest of the city.[2] Another reason for moving the glassmakers to Murano was that Venetian glassmakers developed secret recipes and methods for making glass, and the concentration of Venice's glassmaking on the island of Murano enabled better control of those secrets.[2]
Murano became Europe's luxury glassmaking center, peaking in popularity in the 15th and 16th centuries. According to historian W. Patrick McCray, the Murano glass industry’s rise in the Renaissance was shaped by a close interplay of consumer demand, skilled craftsmanship, and strict state regulation, which together elevated glass from an artisan product to a luxury art form.[3] Venice's dominance in trade along the Mediterranean created a wealthy merchant class that was a strong connoisseur of the arts. This helped establish demand for art glass and more innovations. The spread of glassmaking talent in Europe eventually diminished the importance of Venice and its Murano glassmakers. The occupation and dissolution of the Venetian state by Napoleon Bonaparte in 1797 caused more hardship for Murano's glassmaking industry. Murano glassmaking began a revival in the 1920s. Today, Murano and Venice are tourist attractions, and Murano is home to numerous glass factories and a few individual artists' studios. Its Museo del Vetro (Glass Museum) in the Palazzo Giustinian contains displays on the history of glassmaking as well as glass samples ranging from Egyptian times through the present day.
Late Antiquity and Middle Ages
The Venetian city state grew during the decline of the Roman Empire in the fifth century, as people fled the barbarian invasions to the safety of islands in the Venetian Lagoon. Small communities grew in the lagoon, among which Venice eventually became the most prominent. The city of Venice became a highly successful trading port, and by the beginning of the 11th century dominated trade between Europe, North Africa, and the Middle East. It also had a strong navy. Many European Crusaders passed through Venice on their way to and from the Holy Land. Treasures of many kinds were bought and sold in Venice: spices, precious metals, gemstones, ivory, silks—and glass. Successful trade bred a wealthy merchant class in addition to the nobles, and the wealthy became patrons of Venice's famous art and architecture.[4]
It is thought that glass production in Venice began as early as 450, when glassmakers from Aquileia fled to the islands to escape barbarian invaders. The earliest archaeological evidence of a glass factory in the area comes from the Venetian lagoon island of Torcello and dates from the seventh or eighth century.[8] The original Venetian glassmakers were joined by glassmakers from Byzantium and from the Middle East—which enriched their glassmaking knowledge.[7]
Major products and innovations
The Venetian glassmakers of Murano are known for many innovations and refinements to glassmaking. Among them are Murano beads, cristallo, lattimo, chandeliers, and mirrors.[16] Additional refinements or creations are goldstone, multicolored glass (millefiori), and imitation gemstones made of glass.[24] In addition to guarding their secret processes and glass recipes, Venetian/Murano glassmakers strived for beauty with their glass.[25]
Aventurine
Aventurine glass, also known as goldstone glass, is translucent brownish with metallic (copper) specks. It was developed by Venetian glassmakers in the early 15th century.[26]
Golden age, decline, and revival
The 16th century was the golden age for Venetian glassmaking in Murano. Major trading partners included the Spanish Indies, Italy, Spain, Ottoman Turkey, and the German-speaking states.[53] At least 28 glassmaking furnaces were in Murano in 1581.[54] Numerous leaders and dignitaries visited Murano during this century, including the queen of France, dukes, princes, generals, cardinals, archbishops, and ambassadors.[55] Collectors of Murano glass included Henry VIII of England, Pope Clement VII, Emperor Ferdinand I, Francis I of France, and Philip II of Spain.[56]
During the 16th century Murano glassmakers liberated themselves from the imitation of metalwork shapes, which had previously been their habit. Shapes became elongated and elegant, "then more elaborate and inclining to fantasy", for example in the hot-work pieces added to the sides of the stems of glasses. The glass was extremely thin, and therefore fragile, adding to the effect of luxury.
Making glass
From its beginning until the fall of the Venetian Republic, Murano glass was mostly a very high quality soda–lime glass (using today's terminology) that had extra attention focused on its appearance. Glass from that time typically contained 65 to 70 percent silica.[70] A flux, usually soda (sodium oxide as 10 to 20 percent of the glass composition) was added to enable the silica to melt at a lower temperature. A stabilizer, usually lime (calcium oxide as about 10 percent of the glass) was also added for durability and to prevent solubility in water. Small quantities of other ingredients were added to the glass, mostly to affect appearance.[71] Sand is a common source for silica. For certain types of glass, the Murano glassmakers used quartz as their source for silica. Quartz pebbles were crushed into a fine powder. Two sources for sand were Crete and Sicily. Quartz pebbles were selected from the Ticino and Adige rivers in Northern Italy.[72] Their source for soda was what they called allume catina—plant ash found in the eastern Mediterranean countries of the Middle East.[70]
Today
Some of Venice's historical glass factories in Murano remain well known brands today, including De Biasi, Gabbiani, Venini, Salviati, Barovier & Toso, Pauly, Berengo Studio, Seguso, Formia International, Simone Cenedese, Alessandro Mandruzzato, Vetreria Ducale, Estevan Rossetto 1950 and others. The oldest glass factory is Antica Vetreria Fratelli Toso, founded in 1854.[81]
Overall, the industry has been shrinking as demand has waned. Imitation works (recognizable by experts but not by the typical tourist) from Asia and Eastern Europe take an estimated 40 to 45 percent of the market for Murano glass, and public tastes have changed while the designs in Murano have largely stayed the same. To fight the imitation problem, a group of companies and concerned individuals created a trademark in 1994 that certifies that the product was made on Murano. By 2012, about 50 companies were using the Artistic Glass Murano® trademark of origin.
Glassmaking is a difficult and uncomfortable profession, as glassmakers must work with a product heated to extremely high temperatures. Unlike 500 years ago, children of glassmakers do not enjoy any special privileges, extra wealth, or marriage into nobility. Today, it is difficult to recruit young glassmakers. Foreign imitations, and difficulty attracting young workers, caused the number of professional glassmakers in Murano to decrease from about 6,000 in 1990 to fewer than 1,000 by 2012.[82]
