The use of vitreous enamels contributed to the decline of traditional stained glass in the 17th and 18th centuries by fundamentally altering the medium's aesthetic and structural purpose. As artists began painting with enamels on glass, the window was increasingly treated as a translucent canvas for pictorial painting rather than a mosaic of colored glass.12

This shift had several detrimental effects:

Destruction of Design Integrity: The traditional use of lead lines—which previously served as essential structural and design elements—was undermined. Leading was reduced to a mere grid holding square sheets of glass together, effectively turning the window into a picture set behind a frame.2
Aesthetic Limitations: Enamel colors were often translucent rather than transparent, generally pallid, and lacked the durability of traditional glass colored with metallic oxides.1
Divorce from Architecture: By attempting to mimic the spatial illusions of Baroque painting, stained glass lost its artistic affinity with the architecture it was meant to adorn. This led to a final decline where the medium became disconnected from its historical role as a structural and decorative unity.23
