CHAPTER II
CHAKRAPANI
(Circa 1060 A. D.)
Black Sulphide of Mercury (KAJJALI) or Æthiops Mineral
The first process consists in the purification of mercury.
"Quicksilver, rubbed repeatedly in the juice expressed from sesbania aculeata, ricinus communis, zingiber and solanum nigrum, becomes purified."
"Take one part of mercury and one part of sulphur, rub the two together in a mortar and thus prepare kajjali or rasaparpati.[1]"
- ↑ Chakrapáni himself claims its discovery or at any rate its introduction:रसपर्पटिका ख्याता निवद्धा चक्रपाणिना। Vrinda, however, recommends its use as well.
