Also they are melted into a yellow transparent glass, neither is there taught an easier way of reducing Antimony by it self into a yellow transparent glass, where crude Antimony is first sublimed, and being sublimed is melted into glass. This sublimation serves instead of calcination, by the help whereof 20 pound are more easily sublimed, than by the help of the other one pound is brought into calx. Neither is there here any danger of the ascending fumes, because when the Antimony is cast into the fire you may be gone, which is a safe, and easy calcination, whereas the common way requires the continual presence of the artist stirring the matter, who also takes out the matter when it is once grown together, and grinds it again; by which means he hath much to do, before the matter come to a whiteness; but by our way, the matter is at the first time made sufficiently white, and more than by that common way of calcination and agitation. I suppose therefore that I have shewed to him that will make glass of Antimony, the best, and hitherto unknown way; which being taught, I hope there is no man will hereafter like a fool go that tedious way of the Antients, but rather follow my steps. For by this way may any Physitian, most easily be able to prepare for himself vomitive and diaphoretical flowers, and also glass of Antimony _per se_. Of those Flowers may be made oyls both sweet and corrosive, and other medicaments, as hath been above said of the spirit of salt, and shall afterwards be spoken in the Second Part. Let him that will make Flowers of the Regulus, fairer than those which are made of crude Antimony, cast it being poudered into the fire, and in all things proceed as hath been said, and he shall have them, _&c._ for they are easily sublimed. Now, how the regulus is to be made after a compendious manner, you shall find in the Fourth Part. The scoriæ also are sublimed, so as nothing is lost. But he that will make Flowers that shall be dissolved in the aire into a liquor must add some calcined tartar, or some other fixt vegetable salt, and he shall have Flowers that will be dissolved in any liquor: but he that will make red Flowers as well those that are diaphoretical, as those that are purging, must mix iron, and he shall have Flowers like to Cinnabar: Let him that desires green, mix copper, if purple, _lapis calaminaris_.
