CHAP. CVI. To make a Paste for an Oriental Granat.

THE Granat is very like the Carbuncle, for both being exposed to the Sun, they exhi∣bit the Colour of live burning Coals, being be∣tween Red and Yellow, which is the true Colour of Fire.

There are several sorts of Granats, both Oriental and Occidental, some deeper, others less so; but the Jewellers know how to make them appear, by set∣ting them on Silver Foils.

We will not trouble the Reader with all that might be said concerning them, several Authors ha∣ving largely treated thereof, we shall content our selves with shewing here the way how to imitate them by our Art.

Take two Ounces of Natural Crystal prepared, and six Ounces of Minium, with sixteen Grains of Manganese of Piedmont, and two Grains of Zaffer, prepared as we have shewn in the first Book, the whole pulverized, and well mixed together, and put in a Crucible into the Furnace, with it's Cover well luted, there to Bake, with the same Precau∣tion we heretofore have given; and you'll have a very fine Granat, ••as resplendent as the Ori∣ental.
