Alongside many decorative arts, the artists of the
Groupe de Saint-Luc
invested in all fields of the glass arts during the first half of the 20th century and beyond. They reinvented traditional modes of expression and techniques, modernizing them in terms of composition, style and the use of diverse materials. Besides traditional arts such as leaded stained glass and reverse glass painting, they discovered other innovative processes, such as
dalle de verre
and stained-glass art without lead cames. Amidst this varied panorama, innovative aspects are dealt with, ranging from the importance of the creative process as reflected in graphic works, to the economic issues that shaped the construction sites. This research brings to light some documents that have never been seen before, offering a new perspective on this heritage.
