Direct evidence for metallic mercury causing photo-induced darkening of red cinnabar tempera paints
Photo-induced darkening of red cinnabar (α-HgS) often dramatically changes the appearance of artworks, but the reduction mechanism of Hg2+ remains unclear. Here, the authors propose an alternative pathway for the blackening reaction of cinnabar, considering its semiconductor properties and pigment-b...
