Mix together yellow, pink, and white lead. This colour is only proper for distemper. Mix together realgar and orpiment; some object to this mixture on account of the poisonous nature of the ingredients. The same colour can be obtained by mixing yellow-pink with Naples yellow; but it is then only fit for distemper. For this colour mix red lead and yellow ochre.
White, with a little lake and blue verditer, make a good cloud colour for that part next the horizon. Crimson. Lake and white, with a little vermilion, shaded with lake and carmine. Flame Colour. Vermilion and orpiment, heightened with white. Another. Gamboge, shaded with minium and red lead. Flesh Colour. Ceruse, red lead, and lake, for a swarthy complexion, and yellow ochre. Another.
To feed and support this fire steadily, he suggested a compound of butter, salts, and orpiment, lodged in metallic tubes, which, he imagined, would at the same time heighten the whole effect by emitting a variety of musical tones like an organ!
Always he remembered: " comrades Old playmates on new seas When as we traded orpiment Among the savages A thousand leagues to south'ard And thirty years removed They knew not noble Valdez, But me they knew and loved.
But a much finer Colour is promis'd by some of the Empiricks, that pretend to Secrets, who tell us, that Orpiment, being Sublim'd, will afford among the Parts of it that fly Upward, some little Masses, which, though the Mineral it self be of a good Yellow, will be Red enough to emulate Rubies, both in Colour and Translucency.
And sometimes too I have doubted, whether the produced Green might not be partly at least deriv'd from this, That the Beams that Rebound from the Corpuscles of the Orpiment, giving one kind of stroak upon the Retina, whose Perception we call Yellow, and the Beams Reflected from the Corpuscles of the Bise, giving another stroak upon the same Retina, like to Objects that are Blew, the Contiguity and Minuteness of these Corpuscles may make the Appulse of the Reflected Light fall upon the Retina within so narrow a Compass, that the part they Beat upon being but as it were a Physical point, they may give a Compounded stroak, which may consequently exhibit a Compounded and new Kind of Sensation, as we see that two Strings of a Musical Instrument being struck together, making two Noises that arrive at the Ear at the same time as to Sense, yield a Sound differing from either of them, and as it were Compounded of both; Insomuch that if they be Discordantly ton'd, though each of them struck apart would yield a Pleasing Sound, yet being struck together they make but a Harsh and troublesome Noise.
Cadmium sulphide, lead chromate and orpiment. Green Pigment. Black Pigment. Lamp black. This is one of the pigments for black lacquer, but does not give a brilliant colour, therefore it is better to prepare the black lacquer by adding iron powder or some compound of iron to the lacquer. Various mixed colours are obtained by mixing some of the above-mentioned pigments.
The following gives in the first place, a red, which passes to blue, then to pale lilac, and finally to white: orpiment, 75 grains; crystallized sal-sodæ, 150 grains; and water, 10 oz. The following gives a yellow-brown: salt of nickel, 75 grains; sulphate of copper, 75 grains; chlorate of potash, 75 grains; and water, 10 oz.
But the most valuable productions at present imported from Thibet are mineral. Immense quantities of salt are brought over the Himalayas on sheep's backs; gold-dust, borax, sulphur, antimony, arsenic, orpiment, and medicinal drugs are also imported into Nepaul.
I will not insist to this purpose upon the Examples afforded us by yellow Orpiment, and common Sea Salt, from which, sublim'd together, Chymists unanimously affirm their White or Crystalline Arsenick to be made: But 'tis not unworthy our noting, That though Yellow Orpiment be acknowledg'd to be the Copiousest by far of the two Ingredients of Arsenick, yet this last nam'd Body being duely added to the highest Colour'd Metall Copper, when 'tis in fusion, gives it a whiteness both within and without.
