Glasmalerei-Konservierung — Kölner Dom
The conservation of the Cologne Cathedral's medieval stained glass — the most significant Gothic stained glass program in Germany, spanning from 13th-century grisaille windows through to Gerhard Richter's controversial contemporary pixel window (2007). The glass conservator reads the correct cleaning and consolidation state of lead-came stained glass through a transmitted-light assessment that differs from the Gutenberg Bible vellum reading (CRAFT-1214) and the optical glass inspection (CRAFT-1242) in applying transmitted light to a colored, leaded glass panel where the structural lead came must be assessed alongside the glass itself.
