Evidence
"Degrade silver contains 57% of grey colour analysed [in MS 22-1948]"
Remarks
In MS 22-1948, 57% of grey samples are actually degraded silver (p. 172). Painters in less valuable manuscripts sometimes mixed silver with gold and orpiment to reduce costs while attempting to maintain a metallic appearance (p. 182).
