Stained glass does not simply contain color; thickness, paint, silver stain and leadwork choreograph transmitted light.

The furnace writes through transformation
Glass, enamel and ceramics become radiant through controlled heat, atmosphere and cooling—processes that often remain invisible in a finished object.
Separate heat from flame
Kiln work depends on temperature, duration, atmosphere and cooling, not simply on dramatic flame. A finished colour may record chemistry more than the appearance of the firing.
Treat variation as evidence
Bubbles, streaks, iridescence and local reduction can carry process information. They should not automatically be framed as either defects or proof of spontaneity.
Respect workshop specificity
Raku, stained glass, lusterware and enamel use distinct materials and sequences. Similar glow does not make their techniques interchangeable.
