“There are some peculiar preparations of gold, silver, and mercury; also of naptha, petroleum, and other bituminous oils. Alchemists also name the oil of camphor and amber, the Lapis asbestos seu Amianthus, the Lapis Carystius, Cyprius, and Linum vivum seu Creteum, as employed for such lamps.
They affirm that such matter can be prepared either of gold or silver, reduced to fluid, and indicate that gold is the fittest pabulum for their wondrous flame, as, of all metals, gold wastes the least when either heated or melted, and, moreover, can be made to reabsorb its oily humidity as soon as exhaled, so continuously feeding its own flame when it is once lighted.
The Kabalists assert that the secret was known to Moses, who had learned it from the Egyptians; and that the lamp ordered by the “Lord” to burn on the tabernacle, was an inextinguishable lamp.
“And thou shalt command the children of Israel, that they bring thee pure oil-olive beaten for the light, to cause the lamp to burn always” (Exod. xxvii. 20).
Licetus also denies that these lamps were prepared of metal, but on page 44 of his work mentions a preparation of quicksilver filtrated seven times through white sand by fire, of which, he says, lamps were made that would burn perpetually.
Both Maturantius and Citesius firmly believe that such a work can be done by a purely chemical process. This liquor of quicksilver was known among alchemists as Aqua Mercurialis, Materia Matallorum, Perpetua Dispositio, and Materia prima Artis, also Oleum Vitri.
Tritenheim and Bartolomeo Korndorf both made preparations for the inextinguishable fire, and left their recipes for it.”
