Stable Copper-Alloy Patina
Green can be stable; colour must be read with adhesion, texture, history and change over time.
Summary
Adherent layer · varied colour · coherent surface. This page connects visible form to an institutional record without reproducing protected object imagery.
What can be observed
Stable patinas vary widely. Even, coherent layers may preserve intentional finish and later history.
What remains uncertain
A photograph cannot establish adhesion, chemistry or activity. Diagnosis belongs to direct examination and documentation.
