calomel n.old name for mercurous chloride, 1670s, from French calomel, supposedly (Littré) from Latinized form of Greek kalos "beautiful" (see Callisto) + melas "black;" but as the powder is yellowish-white this seems difficult. "It is perhaps of significance that the salt is blackened by ammonia and alkalis" [Flood]. updated on October 30, 2022 |
