In Cyprian copper we have the kind known as “coronarium,” and that called “regulare,” both of them ductile. The former is made into
\nthin leaves, and, after being coloured with ox-gall, is used for what has all the appearance of gilding on the coronets worn upon the stage. The same substance, if mixed with gold, in the proportion of six scruples of gold to the ounce, and reduced into thin plates, acquires a fiery red colour, and is termed “pyropus.<\/strong>“<\/strong><\/p>\n

pur\u00f4pos, “sparkling like fire.”<\/p>\n

PLINY THE ELDER,
\nNatural History, Book 34, chapter 2 :<\/p>\n

In Cyprus, where copper was first discovered, it is also procured from another stone, which is called “chalcitis.” This, however, was afterwards considered of little value, a better kind having been found in other regions, especially that called “aurichalcum<\/strong>,” which was long in high request,<\/strong> on account of [p. 6149] its excellent quality; but none of it has been found for this long time, the earth having been quite exhausted.<\/strong><\/p>\n

Regia Solis erat sublimibus alta columnis,<\/p>\n

clara micante auro flammasque imitante pyropo<\/strong><\/p>\n

\u201cThe palace of the Sun towered up with raised columns, bright with glittering gold, and gleaming pyrope like fire ;\u201d<\/p>\n

Wikipedia : A metallurgical\u00a0process for the “the colouration [chr\u00f4sis] of gold” is described in the 15th recipe in Leiden Papyrus X, from Thebes\u00a0in Egypt, dated to the 4th century AD.\u00a0<\/sup><\/p>\n

Auricupride<\/strong> is a natural alloy\u00a0that combines copper\u00a0and gold\u00a0with formula: Cu3<\/sub>Au. It is extremely malleable. A variant called Tetra-auricupride <\/em>exists.<\/p>\n

It is most often found in Chile, Russia and South Africa.<\/p>\n

The semi-mythical metal known as Orichalcum\u00a0may be connected to this alloy.<\/p>\n

Auricupride is presently found in small amunts in Soimon Valley, Karabash (Karabasch), Chelyabinsk Oblast’, Urals Region, Russia<\/p>\n
