LUMEN
Glassblowing studio. Real transmission through blown glass.
About the work
A glass studio whose hero vessel uses physically based transmission — actual refraction through the blown form, with furnace glows baked into the environment so the glass has something true to bend. Scroll re-tints the piece from clear to amber to smoke.
How it was made
The hardest material lesson in the collection: transmission samples only the opaque scene, so glow planes did nothing until the light was baked into the scene background itself, and Beer–Lambert attenuation had turned the glass to ceramic until the absorption length was rebalanced.
Like every work in the exhibition, it passed three full iteration passes — a visual critique, a deepening pass, and a QA pass at 390px with reduced motion and zero console errors — and documents itself in its own build guide.
