زنجفر

زُنْجُفْرٌ ذ A certain dye, [or pigment, ] well known, (K,) of a red colour, with which one writes as well as dyes; [namely, cinnabar: ] its virtue is similar to that of white lead; or, as some say, of شَادَنْج [a kind of stone, used medicinally, from the Persian شَادْنَهْ]: it is of two kinds, native and factitious: the native is [ formed by ] the transition of a sulphureous substance into quicksilver: [ it is a sulphureous ore of quicksilver: ] the factitious [ is what is called vermilion, and ] is of various sorts.
