Recipe Details
Ingredients
silver leaf, vermilion
Evidence
"detail of silver leaf tarnishing, exacerbated by the vermilion pigment on the facing page (fol. 84v), with which the silver metal comes into direct contact when the manuscript is closed."
Remarks
The author identifies silver's reaction to sulfur-containing pigments like vermilion (mercury sulfide). This contact-induced degradation occurs when the manuscript is closed, causing mottled darkening (p. 62).
