Venetian Glass Beads

What are conterie, the Venetian glass beads?

Conterie is the Venetian word for the small glass beads the city made in quantity. Across the whole period from the fifteenth to the seventeenth centuries the term covered every type of glass bead, used both as an ornament for fabrics and jewellery and as currency for exchange (Warwick, 2024, para. 15). The word itself is disputed. The founders of Murano's nineteenth-century museum and archive argued it either way: one reading derived it from contante, meaning cash, in 1864, and the other from contigia, meaning ornament, in 1874 (Warwick, 2024, para. 14). The disagreement is the point, because the bead was ornament and money at the same time.

By the eighteenth century the bead guilds had separated their production into two main types, divided by method of manufacture and by the kind of labour each needed. On one side were the minuscule beads called margarite, monochrome and made in an assortment of colours. They were strung in single-colour or multicoloured threads, sewn into fabrics, arranged in strands for necklaces, bracelets, belts and collars, or sold as trade beads by the sack according to weight (Warwick, 2024, para. 16). On the other side were beads made to order at a lamp, each one worked by hand, larger than the margarite, and formed by winding glass paste onto metal spindles about the size of a coin (Warwick, 2024, para. 17).

Why glass beads were Murano's most profitable product

The decorated goblet and chalice were the recognised emblem of Murano luxury glass. The economic pillar of Venetian glassmaking was the conterie, produced in great quantities and traded throughout the known world (Warwick, 2024, para. 6). Beads functioned as currency on a par with metal coin, and merchants' manuals measured the goods of the period in them: one pound of beads for a Canadian beaver pelt, five pounds for an enslaved African person (Warwick, 2024, para. 4). The trade in Venetian beads ran directly through the Atlantic slave trade, and the manuals priced it that way.

The reach of the object shows up in institutions as well as prices. All thirteen original American colonies used wampum and glass beads as money, both with first peoples and among themselves, and the Hudson's Bay Company and the Royal Africa Company were colloquially called glass bead companies (Warwick, 2024, para. 4). At the first landfall in the Americas, on 11 October 1492, the log records red caps and glass coronets worn at the neck handed over on the beach, and small glass beads and bells exchanged afterwards for parrots, cotton thread and spears (Warwick, 2024, para. 2).

By the sixteenth century Venetian merchants were naming their stock by where it was going. There were beads of Africa, and others destined for particular regions of India or for the Americas (Warwick, 2024, para. 19).

How were Murano glass beads made?

Mass production of the tiny drawn bead dates to the 1470s, and the chain had five stages (Warwick, 2024, para. 16). Glass workers called tiradori drew cylinders of blown glass out into long hollow tubes, or canes, which were then cut into concentric rounds. The small rounds went into a steel tray called a ferraccia and softened gently in a furnace, turning continuously so that the cut edges melted into rounded beads. They were loaded into sacks of sand and shaken by workers called lustradori until they took a mirror polish. Once washed, the beads travelled by boat across the lagoon in large vats, to be handed to the women of Cannaregio for stringing. Most were threaded onto fabric and packed into bags for use as currency, while some were strung on fine metal wire so they could be arranged into ornamental work, usually floral motifs.

The method survived into the industrial period. From the end of the nineteenth century the beads were still made by cutting hollow canes into short cylinders and rounding them while hot in metal trays called ferrazze (Fondazione Musei Civici di Venezia, 2026).

The other technique worked one bead at a time. Oil lamps served as small furnaces to soften thin threads of coloured glass, known as vette, which were wound onto a metal spindle (Warwick, 2024, para. 17).

The impiraresse, the women who strung the beads

The division of labour in Venetian glass ran along lines of sex. The makers of glass paste and the blowers at the Murano furnaces were men. Bead production for the trade mainly occupied female labour, in the poorer quarters of the city, from Cannaregio to Castello, where women worked as perleri, shaping glass paste over an oil flame, and as impiraresse, threading the minuscule conteria beads onto cotton (Warwick, 2024, para. 7).

The stringers worked in the open. They gathered in the shared courtyard of their neighbourhood, and their song set the rhythm of the gestures of arms and hands, turning physical work into the work of living machines. The tools were specific to the trade: a palmetta of needles spread out like a fan, an extension of the fingers, with which a woman fished beads out of a sessola, a concave wooden tray held in the lap and named for the sassola that sailors used to bail water out of boats (Warwick, 2024, para. 11).

This was piecework at industrial speed, valued for rapidity, quantity and precision, and it had spread through the courtyards of Cannaregio by the middle of the fifteenth century (Warwick, 2024, para. 12). It lasted into the early twentieth century, long enough to be painted: The Bead-Stringers of Venice, an oil of 1880 to 1882, hangs in the National Gallery of Ireland in Dublin (Warwick, 2024, fig. 2).

Maria Barovier and the rosetta bead of 1497

The Barovier family had been settled on Murano since the end of the thirteenth century, and it was to Angelo Barovier that the Venetian state granted a first patent for cristallo glass, generally dated to about 1455 (Warwick, 2024, para. 25). What matters for beads is that his workshop was not judged on vessels alone. The architect Filarete praised it for its prized vases and chalices with their enamels and gilding, and also for its beads, and held that novelties in bead production carried the same weight as those brought to princely goblets (Warwick, 2024, paras. 26, 27).

Around 1470 came the technical development that produced the beads visitors still recognise: drawn glass rods that could be fused in polychrome combinations, cut into concentric rings, and re-fused into objects, including the beads known as millefiori for their flower of colour (Warwick, 2024, para. 28).

The best-known design is attributed to Angelo's daughter. A ducal decree of 1497 granted Maria Barovier the patent for the rosetta, a cane of superimposed colours mould-fused into a star formation; cut across, the rings of colour read as a star or flower, hence rosetta, and later stellaria. Beads whose edges were rounded into a globe were later called chevron, for the zig-zag the finish produces (Warwick, 2024, para. 29). Scholars still debate how much of the making was hers, though the decree calls her the inventor, and an inventory of 1496 lists objects made a rosetta with her signature (Warwick, 2024, paras. 30, 32).

From the 1898 merger to the factory that closed in 1993

The bead trade outlasted most of Murano's other business and then became a factory. Scholars have traced a vast traffic in glass beads from Europe to the United States that continued to the end of the nineteenth century, with around 2,700 tonnes a year arriving in New York alone (Warwick, 2024, para. 5).

In 1898 several Murano firms making beads merged into a single large company, the Societa Veneziana Conterie, housed in a complex between Palazzo Giustinian and the Basilica di San Donato. Between 1940 and 1970 it employed more than three thousand people. It closed in 1993 (Fondazione Musei Civici di Venezia, 2026).

That arc explains the shape of the craft today. The hand stringing in the courtyards ran in parallel with the factory for decades, lasting into the early twentieth century, which is unusual in the history of early modern crafts though not anomalous (Warwick, 2024, paras. 11, 12). What the bead carried with it was a whole set of working lives: the traders who exchanged beads for furs in the North American forest, the sailors who exchanged them along the coasts of Africa and on to India for ivory, gold, spices and slaves, the Venetian silk workers who sewed beads into their fabrics, themselves generally women, and the goldsmiths of Castello who turned glass-paste beads into jewellery (Warwick, 2024, para. 36).

Where to see Venetian glass beads on Murano

The place to start is the glass museum on Murano, where the former bead factory itself is part of the visit. Spazio Conterie is an exhibition hall made from the restored factory complex: an open space about seven metres high that keeps the original arches and entablatures, lit partly by daylight from the Fondamenta Giustinian side, and hosting temporary exhibitions and events in rotation on the ground floor (Fondazione Musei Civici di Venezia, 2026). Checking what is showing before a trip out is worthwhile, since the programme changes.

The museum's own bead holdings include a Murano bead of the late fifteenth century made with rosetta canes and gold leaf, which is the object at the centre of this history (Warwick, 2024, fig. 1). Three further pieces published with the same research give a sense of how far the bead travelled: a Venetian woman's cap embroidered with glass beads, dated about 1500 to 1525, in the Metropolitan Museum of Art; a rosetta or chevron bead of about 1600 to 1700 in the Corning Museum of Glass; and the painting of the bead-stringers in Dublin (Warwick, 2024, figs. 2, 3, 4).

One Venetian habit is worth knowing before shopping. Glass-paste imitation gems, called veriselli or verixelli in dialect, were made by the same lamp workers and were among the island's main exports (Warwick, 2024, para. 17).
