CHAP. CXXXIII. Another fairer Jacynth-Colour.

IF this Iacynth be fairer, it is also more brittle than the other, because it has more Lead in it. To make it, take an Ounce of our Crystal in Pow∣der, three Ounces of Minium, and forty five to forty six Grains of Verdigrease. Mix well these Matters together, after having pounded them well in a Brass Mortar, and searced them through a fine Sieve. Then put them into a Crucible covered and luted in a Glass-house Furnace, where let it stand twelve Hours. Then take out the Matter, which pound and sift well; then put that Powder into another Crucible covered and luted, which put into the same Glass-house Fur∣nace for twenty four Hours, and the Matter will be well baked. Then take out the Crucible, to put it in the Annealing Furnace; and twelve Hours af∣terwards take your Matter out of the Crucible, which will be of a fine Iacynth-colour, and may be Wrought.
