Thanks to the artistry of the designers, artist Véronique Ellena, master glassmaker Pierre Alain Parot and the expert team at Saint-Gobain GLASSOLUTIONS, who used their advanced Dip-Tech digital ceramic in-glass printer, this novel stained glass installation was able to achieve a convincing historic look that fully blends with the existing façade and original stained glass.
» Capturing beauty and the diversity of the world
A historic site like Strasbourg Cathedral required artwork that was both contemporary, while at the same time showed a distinct connection to the past. In addition to sheer beauty, it also needed to meet distinct aesthetic and functional requirements.
The artist Véronique Ellena who designed the project, described her goal as conveying 'the beauty and diversity of the world' on glass. She photographed everyday people who came to the cathedral to bring their transfigured colors to the light that penetrates through the stained-glass in the cathedral. As a photographer, it was a way to draw the light on the stained-glass.
The end result was an image of the face of Christ, inspired by Hans Memling’s painting 'Christ’s Benediction'. His face is made up of a montage of 150 of the anonymous faces Ellena photographed. In the installation, Christ’s face is on the right panel, and the left panel pays homage to nature.
Ellena, together with Saint-Gobain GLASSOLUTIONS and Dip-Tech, then converted her graphic images into a ready-to-print file formatted for printing directly on glass.
» Glass print designed to last 1,000 years
Saint-Gobain, owner of three Dip-Tech digital glass printers, introduced the solution of digital ceramic in-glass printing, knowing it would meet the artist’s distinct requirements.
Besides the need for creating colorful detailed images, the artist wanted to ensure longevity for the project. Or as Jean-Francois Outin, Interior & Design Market Director at Saint-Gobain described it, a solution that would last, along with the cathedral itself, for at least another 1,000 years. As such, Outin explained: It was clear to us from the beginning that ceramic colors would need to be infused into the glass, as organic inks would not stand the exposure to air and humidity.
Working together, the industrial process was soon transformed into an artistic process, as the team implemented tests on glass, tweaking the design until the perfect printed results were achieved.
» Revealing the masterpiece
Master glassmaker Pierre-Alain Parot, who was the technical advisor to Véronique Ellena from the beginning of the project, was enlisted to put the final touches on the glass. He created a blown glass second skin that was applied over the printed imagery. The stained glass further enhanced the image and feel, creating the perfect blend with the existing Gothic artwork. The final result is a 7.8 meter high photomontage consisting of 40 printed panels.
Dip-Tech technology of digital in-glass printing, enables to plan how the entire image will be printed on each panel. Then, the glass processor actually print different part of the image on each panel, number it and make it easier for the construction team to build it in the correct way, revealing the masterpiece.
While this was glass master Parot’s first time working with digitally printed glass, he was impressed by its functionality. The ability to reproduce photos on the glass with a sustainable technology allows the traditional stained glass painter to enter a new era, he said.
The Strasbourg Cathedral was an historic opportunity to highlight what digital ceramic in-glass printing can do. We’re impressed by what our partner Saint-Gobain was able to achieve – successfully bridging the artwork from millennium to millennium – and we look forward to continuing to develop our technology to match evolving market needs, commented Dip-Tech CEO, Alon Lumbroso.
