زنجفر
زُنْجُفْرٌ 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. (TA.)
