CHAP. CLXII. The Way to make Yellow Enamel.

YELLOW is the Colour of Gold, and may there∣fore deserve all its Commendations, which are so extraordinary great, that they require a whole Volume to contain 'em; but we'll only satisfie our selves to intimate, that it bears the likeness of the first and more perfect Body, which rouls under the Heavenly Arch: And can there be any other so great Comparison? 'Tis likewise the Symbole of true No∣bility, and of all excellent Causes.

You may make this rich Colour with six pound of Principal Powder, three Ounces of Tartar, seventy two Grains of prepared Manganese, the whole redu∣ced to an impalpable Powder, well mixt and put in∣to a glazed Earthen pot large enough to dispense with the Ebullition and raising up of the Metal; let it stand in your Glass-house Furnace to melt and in∣corporate; after cast it into Water, dry it, and leave it in the pot again to refine very well; then try the Colour, and if it be sufficient, make it up into Cakes as before directed, and you'll have a very ta∣king Yellow Enamel for all sorts of Metal but Gold, which by its resemblance it would only dull and spoil

the Beauty, unless it were placed among other Co∣lours, as the Goldsmiths already are very well ac∣quainted withal.
