A certain Allome exalting and fixing any colour, especially requisit for scarlet and other pretious colours, with a certain perpetual cauldron, that doth not alter colours, and is not costly. A making of colours for painters, as of purple gum, ultra-marine, not costly, and especially of that rich white, never before seen, like to Pearl and Margarites; also a peculiar colouring of gold and silver. To conclude, I refer the Reader unto the Residue of my Books, that Treat of those Secrets more plainly; which I am resolved shortly to put forth. * * * * * _Those Secrets are all openly taught in the following Treatises, as in the Explication of Miraculum Mundi, Apology against Farner, Prosperity of Germany, =&c.=_ _FINIS._ Of the Tincture of Gold, Or the True AURUM POTABILE: _What it is, and how it differs from the false and sophisticated Aurum Potabile: How it tis be Spagirically prepared; And how to be used in Medicine._ _Of Aurum Potabile._ There is no man that can deny, that the true and ancient Philosophers did study long life, and the conservation of their health. Whence it came to pass that they did diligently seek out the subject of preserving health, and prolonging life: wherefore by the help of fire they did practise the separations, and proofs of all vegetables, animals, and minerals, seeking out their powers and vertues: Who found out the greatest harmony of all things as well in the heavens, as on earth, betwixt the Sun, Gold, Man and wine. For it cannot be denyed, that the life of all things proceeds from the heat of the Sun; wherefore they sought to unite gold the terrestrial sun or body fixed and perfect, caused by the rays of the sun, with man by the help of spirit of wine.
