Brosse: Preserving Handwork in Semi-Automatic Perfume-Bottle Making

“The human eye is indispensable.”

Laurent Santarelli, director of the Vieux-Rouen-sur-Bresle plant in 2015 (translated from French)

Designing a perfume bottle does not end with drawing its outline. There is the shape visible from the outside, and the shape of the interior that holds the liquid. Where should the glass between them be distributed, and in what quantities, so that the same result can be reproduced bottle after bottle? The small vessel surrounding a fragrance contains a great deal of work that turns a design into a manufactured object.

Brosse is a French glassmaker that has worked at this intersection. Previously known as Verreries Brosse and then Zignago Vetro Brosse, it is now called Zignago Vetro France. Its history of retaining semi-automatic methods alongside automated production shows how perfume-bottle manufacturing connects not only with form, but also with quantities, inspection, and the division of work within a region.

Key Facts

Founded: 1892
Former names: Verreries Brosse / Zignago Vetro Brosse
Current name: Zignago Vetro France
Production site: Vieux-Rouen-sur-Bresle, Normandy, France
Main activities: Manufacturing glass containers for luxury perfumery, cosmetics, and premium spirits
Official website: Zignago Vetro

Rather than a brand that composes and sells perfumes, this is a company that turns the containers requested by brands and designers into industrially manufactured products. Its present-day French operation uses both automatic equipment and traditional semi-automatic techniques, offering standard designs as well as bespoke containers.

Glassmaking in the Bresle Valley

From Forest Glassmaking to Perfume Bottles

The Bresle Valley, where the Brosse factory is located, is a concentration of glassmaking businesses on the boundary between Normandy and Hauts-de-France. Glassmaking in the region dates back to the Middle Ages. Around the Forest of Eu, production was supported by timber for furnace fuel and fern ash that supplied potash, an ingredient used in making glass.

In the nineteenth century, the perfume culture spreading among the Parisian bourgeoisie opened a new market. A region making window glass and glassware expanded into supplying containers for luxury perfume. Brosse, founded in 1892, belongs to this local tradition of perfume-bottle manufacturing.

The industrial network now known as La Glass Vallée brings together model makers, foundries, mould makers, glassmakers, sorting businesses, and decorators. The stages required to complete a single bottle are connected through the expertise of different companies.

The 2002 Acquisition and Two Changes of Name

Brosse’s founding and the history of its present parent company need to be distinguished. Italy’s Zignago Vetro acquired Verreries Brosse in 2002. The acquisition brought the expertise accumulated in semi-automatic production for luxury perfume into the group’s product portfolio.

The company became Zignago Vetro Brosse in 2019, then Zignago Vetro France in 2023. An announcement in September of that year also set out plans to integrate Brosse, its luxury-sector brand, into Zignago Vetro. Understanding the company means keeping sight of the work that began in 1892 behind its current name, while not treating an earlier name as the company’s present identity.

Choosing Between Semi-Automatic and Automatic Production

Between Small Series and Large Orders

A distinctive feature of Brosse is its use of semi-automatic manufacturing alongside automatic equipment. Within the same business, it has both a means of handling complex shapes and small orders and a means of producing large series.

In 2008, Marc Cooper, then managing director, said the following about a new automatic furnace scheduled to enter service the next year:

“This will be a fundamental step for us.”

Marc Cooper, 2008 (translated from French)

The planned furnace had a capacity of 55 tonnes per day and represented an investment of €30 million. Beyond enlarging the equipment, what mattered was the ability to coordinate manufacturing within the group. Cooper explained that production could also be transferred to Italy when quantities exceeded the French plant’s capacity. Assuming that every bottle is made exclusively in one factory would miss how this production system works.

In 2015, meanwhile, Brosse explained that automatic equipment could produce at least 30,000 pieces in a day, whereas semi-automatic equipment could be used for a market test or limited edition of 5,000 pieces. This was a comparison of production scales given at the time, not a uniform minimum order quantity applicable today. The value of having both types of equipment was the ability to choose the method to suit the design and quantity, from small series to large orders.

Supporting an Entire Family of Perfume Containers

The perfume world requires more than ordinary bottles. It also uses miniatures, containers for extrait de parfum, glass stoppers, cream jars, and oversized display bottles for shops. The last of these are known as factices. As sizes and uses change, so do the quantities required and the demands placed on the shape.

The group’s current official account also states that combining semi-automatic and fully automatic production allows it to make this range of containers in quantities from a few thousand to large-scale runs. Semi-automatic manufacturing is not simply a historical technique being preserved. Alongside automatic production, it accommodates a wider range of product sizes and quantities.

Designing Both the Outer Contour and the Inner Shape

Up & Down: Adding Thickness at the Shoulder

The glass-distribution technique called Up & Down is a clear example of development specific to Brosse. In 2016, Stefano Bortoli, the group’s commercial director for perfume and cosmetics, described its development organisation as follows:

“We have set up in Verreries Brosse a team focused on development.”

Stefano Bortoli, 2016

The team developed a manufacturing process that places more glass at the bottle’s shoulder, creating a symmetry of thickness between the top and bottom. The current official website also presents Up & Down as a patented technology.

In a bottle with a thick base, a transparent layer is visible beneath the liquid. Up & Down extends that approach to thickness to the shoulder. It coordinates the relationship between the outer shape and the inner space holding the perfume, including the upper part of the bottle. Models with square, circular, rectangular, and oval cross-sections were shown in 2016. Even before decoration is applied to the surface, the distribution of the glass itself gives the bottle its character.

The New Essential Parfums Bottle and Its Mould

The role of the mould in connecting design with volume production can also be seen in the new bottle introduced in 2024 by Essential Parfums. The brand moved from a standard model previously supplied by Coverpla to its own signature bottle.

Alnoor Mitha de Bharat created the design. Brosse made a new mould and proposed an option using recycled glass with sufficient whiteness. The new bottle has more sharply defined edges, a raised support beneath the neck, and the brand’s logo engraved on the base. A shallow recess on the front accommodates the paper label.

“The work was carried out with great delicacy.”

Alnoor Mitha de Bharat, designer of the new bottle, 2024 (translated from French)

The neck, base, and placement of the label change without transforming the overall outline. The glassmaker’s role lies in making the designer’s distinctions reproducible through the choice of mould and material. This new bottle and Up & Down are separate design initiatives.

A Regional Division of Work Connecting Decoration and Inspection

Making the Glass and Finishing Its Surface

The finishing carried out after a bottle is formed is known in French as parachèvement. In 2014, Brosse announced a partnership with Pariche Nigermat, a specialist in this field.

“Decoration is a trade in its own right.”

Olivier Caspar, managing director of Verreries Brosse in 2014 (translated from French)

The partnership allowed a glassmaker to broaden its expressive range by working with another regional specialist. Pariche Nigermat handles frosting, lacquering, screen printing, hot stamping, pad printing, and sandblasting, among other processes. Brosse concentrated its investment on glass production while developing decoration in collaboration with specialists.

The group’s current official account likewise describes both in-house facilities and a network of specialist partners. Its own decoration department is based in Poland, while the French operation has expertise in grinding and polishing glass surfaces. The services offered by the group as a whole cannot all be treated as processes carried out inside the Brosse factory.

Sorting Formed Bottles by Eye and Hand

Work remains even after a bottle has taken shape. In 2024, the sorting company Innoverre was operating inside the Vieux-Rouen-sur-Bresle factory. Established in September 2022, it brought work for the existing partner Serdym onto the factory site. Some bottles that had previously been transported by truck to Embreville, around 35 kilometres away, could now be sorted where they were made.

Sorters look for faults such as wrinkles in the glass, bubbles, tilting, and uneven distribution. A rate of 800 bottles an hour was also reported at the site in 2024. This is physical work that requires more than good eyesight: workers pick up bottles and continually judge their condition within a set time. Rejected glass becomes cullet, fragments used for remelting, and returns to production.

Santarelli’s words at the beginning offer a way into understanding the importance of this sorting work. The distinction between semi-automatic and automatic forming alone cannot fully explain the quality of a finished bottle. A mould gives it shape, glass is distributed, the surface is finished, and finally each bottle is checked individually. Brosse’s work connects these stages, turning the design of a perfume container into everyday production.
