Mastering the art of stained glass

For 12 generations, the Atelier Simon-Marq has put its expertise and ancestral craftsmanship at the service of creating and restoring stained glass. Descended from a long line of illustrious master glassmakers, the Workshop benefits from a precious heritage, continually evolving with the innovations and developments in glasswork.

Contemporary artworks

Simon-Marq’s heart beats for art. The studio created the stained glass windows designed by renowned twentieth-century artists such as Marc Chagall and Maria-Héléna Vieira da Silva, helping this religious art form to thrive in France and around the world.

Heritage conservation

For several generations, the artisans of the Atelier Simon-Marq Studio have practiced all type of conservation operations that contribute to the protection, preservation, and enhancement of ancient stained glass. The Workshop strictly adheres to traditional practices while closely monitoring the evolution of techniques.

lead cames

Creation with the artist

The “cames” are the lead rods that are arranged in a particular pattern and which hold the stained glass in place. Creating a pattern of cames for a stained glass artwork requires artistic sensitivity and technical skill in order to remain faithful to the artist’s intentions while taking mechanical constraints into account. The lattice of cames is like an artwork in its own right, based on enlargements of the original drawing on the scale of the stained-glass window itself.

Rubbing

Rubbing is a technique that provides a full-size representation of the lead cames. A rubbing is usually made by placing a piece of thin paper over the stained-glass panel and rubbing it with a block of waxy or dry material so that the pattern of cames appears on the paper. Much care must be taken so as not to damage the stained glass. This work is necessary to keep a permanent record of a stained-glass panel or as part of a restoration project.

Selecting the glass

Choosing colours

We mostly work with mouth-blown glass, traditionally handcrafted at the Saint-Just glassworks near Saint-Etienne, France. The shimmering colors of each glass sheet vibrate uniquely and intensely. Our extensive color palette includes over 1,100 shades. Selecting just the right tones is essential for the success of each project.

Cutting

The pattern of lead cames is traced onto stiff paper. Each shape is cut out with three-bladed scissors which substract the width of the came. The shapes then serve as templates for cutting out the glass by hand using a tungsten cutting wheel.

Treating the glass

Painting

Made from enamel or metal oxides, the paint and grisaille are applied to the glass before firing. They are used to pick out the shaded parts of a motif or drawing or to add subtle nuances of colour to the original hue of the glass.

Engraving

Extensively used by Marc Chagall and now perfectly mastered, the engraving process allows for gradation of the color on a single piece of glass. By removing more or less of the enamel layer through engraving, the treated glass maintains its transparency.

Sandblasting

The sandblasting process involves projecting fine sand at high pressure onto precise areas of glass, marked out with a stencil. The enamel layer of the flashed glass is scrubbed off, creating very precise patterns. On the areas where it has been sandblasted, the glass becomes opaque.

Assembly

Mounting and puttying

Since the Middle Ages, stained glass has traditionally been set in lead cames, held together by soldering at each intersection. Putty – a mixture of linseed oil, soot, chalk, and a drying agent, according to the Studio’s unique recipe – is then applied to each panel, ensuring their waterproofing and rigidity. The Workshop continues to use this time-tested technique of leading and glazing, ensuring a lifespan of approximately 100 years for the treated stained glass windows.

Modern techniques

The fusing technique offers a new means of expression, more flexible and pictorial, by fusing layered glass pieces during firing. Glass collage allows for the juxtaposition and assembly of pieces on mechanical glass, also paving the way for the creation of pieces with non-standard dimensions. Finally, brass also allows for glass assembly, serving as a more durable substitute for lead. Opening the door to new graphic compositions, these creative solutions exist today to avoid the use of lead.

On-site operations

Installing stained glass

The Atelier Simon-Marq also ensures the installation of its stained glass in all types of buildings or homes. We combine our expertise with that of other trades, including for the creation of metal or wooden frames. Depending on the installation, protective glazing can be added with a simplified lead pathway.

Removing stained glass

During restorations, we also carefully remove the ancient stained glass windows. Once our intervention in the workshop is complete, we perform the final step: reinstalling the restored stained glass, thereby restoring the work to its former magnificence.
