Antimony metal is evolved as a gas by homogeneous mixtures of monosulfide stoichiometry and spritzels of that stoichiometry. See the photomicrograph of antimony regulus sublimed from a microgerb of the mix ... 

Siemens and Halske, equal parts of zinc and cadmium and 10 per cent. Sb. t It can be made thus —Melt separately 4 parts of copper, 12 parts of Banca tin, and 8 parte of antimony regulus, and, after fusion, d 12 parts of tin. The antimony is added to the first portion of the tin after its fusion, and the copper is introduced after the vessel is taken off the fire and before its content is poured out. The charge is kept from oxidation by a layer of powdered charcoal. A small percentage of aluminium added to the mixture gives a good result.

The type is cast in a mould that can be opened and shut very quickly. The metal, which is ladled into it, consists of lead, arsenic and regulus of antimony. At the same time as the metal enters the mould... a rapid movement is made by the hand holding the mould, which increases the pressure on the bottom where the actual letter is formed.

In the treatment of these subjects Porta includes statements of the ancients from the time of Theophrastus and Aristotle, as well as the contemporary knowledge of his own time, not always with any critical discrimination between the ancient interpretations and the more modern facts. Thus under the heading To change stibium into lead 37 he says, if you frequently heat and burn stibium which the chemists call regulus you will burn it into lead, because we see it noted by Dioscorides saying, Stibium if heated somewhat further is turned into lead. The chemists of Porta s time by the regulus of antimony or stibium, meant metallic antimony, and no longer considered... 

Woe unto you, who neither understand nor care to understand my words If you knew the meaning of fixation and volatility, and of the separation of pure and impure, you would cease from your foolish occupations and follow me alone. It is I, Antimony, that speak to you. In me you find mercury, sulphur, and salt, the great principles of health. Mercury is in the regulus, sulphur in the red color, and salt in the black earth which remains. Whoever can separate these, and then re-unite and fix them by art, without the poison, may truly call himself blessed for he has the Stone, which is called fire, and in the Stone, which can be composed out of Antimony, he lias the means of perfect health and temporal subsistence. ... 

The writings of Sylvius were first published between 1659 and 1674, all on medical subjects primarily, unless we except his brief treatise on Chemical Medicines,10 which is practically confined to the various medicinal compounds of antimony— flowers, liver, regulus, glass, antimony diaphoreticum, butter of antimony, the latter made by distilling crude antimony (that is sulphide) with mercury sublimate (that is mercuric chloride). These compounds were, however, all known by 1600 and well summarized in pseudo-Basilius s (Tholden s) Currus Tri-umphalis Antimonii. 

Equal weights of antimony pentoxide and pure potassium cyanide are treated as above. The regulus is washed with hot water for the removal of impurities. 

This metal is obtained on a commercial scale both by reducing antimony oxide with carbon and by reducing antimony sulphide by means of metallic iron. The second method possesses the advantage that antimony sulphide, a natural product, is used directly and does not need to be first converted into the oxide. The iron sulphide formed by this method is fusible and forms an immiscible layer which floats on top of the molten antimony. The addition of borax facilitates the separation of the liquid layers, and thus the globules of melted antimony are allowed to sink more easily to the bottom of the crucible and form a metallic regulus. The upper layer furthermore covers the surface of the metal and hinders its oxidation and the escape of the volatile Sb203.
