Chevron Beads (also known as “rosetta” beads, or simply “Chevrons”) are a type of Venetian Trade Bead produced in Murano and Venice, Italy, from the 14^th to 19^th Century. Venetian Chevrons are categorized as ‘drawn’ beads; created by fusing multiple glass canes which are shaped using specialist star molds. This creates a distinctive star shape around the perforation hole (usually comprising 4-7 colored layers), which is often referred to as a “rosetta”. Chevron Beads produced during the 15^th Century typically had 7 layered colors and 6 facets.

Chevron Beads comprise numerous layers of colored glass. The core of the bead, which will later form the perforation, is created from a single globule of molten glass, known as the “gather”. While still hot, the gather is immersed into a star shape mold to add the first layer of color. This process is repeated to achieve each colored layer. After several colors have been layered consecutively, the glass is drawn out, or pulled with a cane to elongate the rod, which is then cut whilst hot to form the beads. The end of the beads are then chamfered or ground to reveal the star pattern in the cross section. Early Chevron Beads were almost always red, white and blue in color.

Venetian Chevrons are among the earliest known types of beads to be produced in Venice for trade in West Africa. They were primarily intended for use as currency in unexplored territories, such as the Republic of the Congo, where merchants would exchange them for favors, animal pelts, slaves and spices. A number of small, 7 layer Chevron Beads dating back to the 15^th Century have been found in Peru, and were believed to have been introduced by Christopher Colombus. Today, classic 7-layer Chevron Beads are the most highly collectible.

Multicolored Prosser Beads

Prosser Beads (also known as Kakamba Prosser Beads) refer to glass Trade Beads made by the Prosser “cold paste” technique, conceived by English brothers Richard and Thomas Prosser in 1840 for the purpose of manufacturing porcelain buttons. The process entails molding cold paste under significant pressure to achieve individual shapes, before it is fired.

Recognizing that the Prosser technique could potentially be adopted for beads, French button-maker and bead collector Jean-Felix Bapterosses bought the rights to the technique sometime in the 1850s. However, Bapterosses soon realized the paste used for the Prosser technique was too inflexible for making beads. After some experimentation, he discovered that the addition of cow’s milk made the paste far more malleable, and also achieved a sheen not dissimilar to porcelain. Inspired by the popularity of Venetian Trade Beads, he began to produce pressed beads on a massive scale at his factory in Briare, France, for use as currency by European merchants.

Prosser Beads were distinct from other European trade beads in that they were produced in a great variety of colors, and were also translucent. They were received particularly well in the town of Kakamba in the Republic of the Congo – hence the name Kakamba Prosser Beads. According to natives, Prosser Beads were deliberately strung upon weak string so that they would break easily, in turn creating an almost constant demand for more. Kakamba natives were also told it was sacrilegious to pick them up, which is why pockets of discarded beads continue to be found on farmland throughout the region.

Trade beads (also known as “aggry” and “slave” beads) refer to glass beads manufactured in Venice, the Netherlands and Bohemia (now the Czech Republic) between the 14th and 20th century. They were an essential component during the establishment of trade networks between Europe, Africa and the Americas from the 16^th Century; used as a primitive form of currency to buy gold, ivory, slaves, fruit and palm oil. Glass beads were popular in Africa since the methods by which they were produced were largely alien to most tribes, thus making them seem all the more strange and valuable. European Trade Beads were particularly prized by tribes in West Africa, such as the Asante, whom used them to decorate their most respected leaders and elders.

Although there is evidence of Trade Bead production in Germany, the Netherlands, France and Bohemia, it was the Venetians of Italy who are largely credited with their gross production. Venetian Trade Beads from the 14^th Century were simplistic in design with just a few colored stripes. These beads are thought to have been the earliest types of Chevron Beads, produced by fusing canes of individual glass together. Chevron Beads (sometimes called Rosetta Beads) are distinguished by a rosetta or star around the perforation hole – the result of layering glass canes symmetrically to produce a uniform striped design.

The popularity of Chevron Beads waned following the introduction of Millefiori Beads to Africa in the late 17^th Century. Millefiori (thousand flower) Beads were made in a similar way to Chevrons, with the exception that canes are solid, rather than hollow, and a far greater variety of colors were used. Prosser Beads, known for their milky sheen, and Dogon Beads, once used to create mosaic gardens in Amsterdam, were also popular during the 19^th Century.

“Venetian trade beads” (also referred to as “Murano beads”, or simply “trade beads”) is a collective term used to describe glass beads of varying design originally produced in Venice, Italy, between the 13^th and 20^th Centuries. They were intended as a basic form of currency, to be exchanged with tribal leaders for spices, furs, gold and slaves, as merchants sought out new avenues for trade in Africa.

Prior to the trade era, numerous glass-makers were known to be producing glass beads in the Rio Alto and Dorsudoro districts of the city on a commission-only basis. As overseas demand grew, the Maggior Consulio (Great Council) realized the great fire risk posed by the glass-making guilds to the city. In 1291, they decreed that all guilds had to be moved to Murano (hence the name), a series of islands in the Venetian Lagoon. Here, under the strict control of the Council, production flourished. Glass-makers developed innovative techniques, such as lampworking and Perle a Lume, to create some of the most ornate beads imaginable.

Distinguished by their striped patina, Chevron (or Rosetta) Beads were among the earliest known decorative beads to be produced in Murano. They are made by fusing rods of colored glass (known as “murrine”) around a single hollow cane, creating a layered rosetta, or star, around the central perforation. The oldest surviving examples date back to the 14^th Century, and are red, white and blue in color. Chevron beads are aesthetically similar to 18^th Century Venetian King Beads, however the latter are almost always biconical in shape.

Millefiori (meaning “thousand flower”) was the name given to a style of Venetian trade bead produced in the 18^th Century. Characterized by beautiful floral mosaics, these decorative beads were highly coveted among African tribes in the 19^th Century. They are made in a similar way to the earlier Chevrons, however, the canes are pulled thin whilst still hot to achieve variations in size.
