CHAP. CXIX. The Way to make an Oriental Emerald.

THE Chapters wherein we have shewn how to imitate this Precious Stone, contain also its Nature and Colours; and all we design to say here, our Intent being not to enlarge on all the Properties of Precious Stones, but only to shew the Means of imitating them, as we shall go on to do.

To make this Oriental Emerald, take ten Ounces of our Matter prepared, of Saturnus Glorificatus, and Natural Crystal, half an Ounce of prepared Ver∣digrease, half a Dram of Foretto of Spain also pre∣pared, as in Chap. 20, the whole reduced into fine Powder, and well mixed together, and put it into a Crucible covered with another, lute it and dry it; then set it in a Glass-house Furnace for three Days, and after in the Annealing Furnace twelve Hours. After which break the Crucible, and you'll find the Matter tinged of a very fine Oriental Colour, which cut and polish as before.
