CHAP. CXVII. To make Balass Ruby.
THIS Precious Stone is of the Nature of a Ruby, since it is found in the same Matter as that. Its very bright colour resembles a Vermillion Rose and Crimson, being mixt of a Natural Red and of a Sky-colour: We will now shew the way to imitate it.
Take six Ounces of Saturnus Glorificatus, mixed with Natural Crystal, as in Chap. 113, half an Ounce of Crocus Martis, half an Ounce of Mercury calcin'd ad Rubedinem, and two Drams of Sal Gem, the whole reduc'd to an impalpable Powder, and mixed well together. Then put it in a Crucible covered close and luted, and so into a Glass-house Furnace for three Days, proceeding moreover as in the preceding Chapter, and you'll have a very fine Matter, the co∣lour of Balass Ruby.
