Of the Preparation of Gold, and its Dissolution into most tender Atoms apt for vivification and profitable application to Medicinal use.
Gold doth not by any way more easily admit of being turned into most tender and most subtil Attomes than by this following.
Dissolve pure Gold in Aq. Regia, and being dissolved pour thereto as much of the Water of Tartar as is sufficient: So the clear Gold, and clothed too with a golden Colour, will precipitate it self to the bottom of the Vessel, nor will it be a darkish Powder, as ’tis wont to be if precipitated by Lixiviums or by the Spirit of Urine: But it is light and tender, and shews in brightness like little golden Stars, yea becomes so very tender and subtil, that it swims as ’twere in the Water and settles to the bottom exceeding leasurely, and is thereby so much worthier than all other Calxes of Gold how subtil soever they be, that they may be accompted of (if compared with this) but onely as a gross Earth; whereas these shining golden little Stars are made so tender and so subtil, as that they may easily discover and demonstrate their Vertues in medicinal use very notably, by the help of other things, and by being dissolved sundry ways.
