Original Recipe Text

Evidence
"Vermilion is the standard name... based on artificially made mercuric sulfide (HgS)."
Remarks
Vermillion is noted for being slightly toxic and prone to darkening to a black substance when exposed to light, particularly when used with an egg tempera binder (p. 3). Impurities in alkali polysulfides can catalyze this red-to-black transition (p. 3).
