By the middle of the 16th century, the technique of painting with vitreous enamels became a major influence on stained-glass design. In this process, granulated colored glass was mixed with a flux of clear ground glass and fired onto the surface of the window.1
This development significantly altered the aesthetic and technical approach to the craft:
- Shift in Transparency: Unlike traditional stained glass, which relied on the inherent color of individual glass pieces, enamel-painted glass was translucent rather than transparent, often resulting in a pallid appearance.1
- Design Flexibility: The technique allowed for more detailed rendering of figures and ornaments directly onto the glass surface. When combined with other advancements like the abrasion of flashed glass and silver stain, it helped liberate artists from the structural constraints of the lead line, which had previously dictated design through the assembly of separate colored pieces.23
- Long-term Impact: While initially used for detail, the technique eventually replaced the traditional use of colored glass, partly due to the scarcity of colored glass caused by 17th-century political disturbances. However, enamel painting was often considered less successful than traditional methods due to its uncertain durability.1
