CHAP. XCVIII. Another very fair Emerald-Colour.

THIS Stone will be far harder and finer than the precedent, because it contains less Lead. To make it, take four Ounces of Natural Crystal, pre∣pared as in Chap. 92, the fourth part of an Ounce of Red-Lead, and the same quantity of Verdigrease, the whole pulverized and sifted fine, which put toge∣ther in a Crucible well closed and luted, in the same Furnace as before, proceeding as in Chap. 94, leaving the Crucible in the Fire thirty six Hours. After which, if you will you may cast your melted Mat∣ter into a Marble Mould heated, putting it near the Fire to cool gently, and you'll have a very fine Eme∣rald.
