Painting with Light
The technique of “painting with light” has been used by stained glass artists since the medieval period. It is a means by which the artist can control the amount of light that is transmitted through the glass, adding another dimension to the piece.
The process involves the painting of lead oxides onto the glass, first as a trace line, then adding and subtracting shading to achieve depth of tone. This “paint” is then fired into the glass in a kiln to form a permanent bond. This process continues through many applications and firings until the desired effect is acheived.
