    en.wikipedia.org/wiki/Jewelry_wire

    Jewelry wire is wire, usually copper, brass, nickel, aluminium, silver, or gold, used in jewelry making. Wire is defined today as a single, usually cylindrical, elongated strand of drawn metal . However, when wire was first invented over 2,000 years BC, it was made from gold nuggets pounded into flat sheets, which were then cut into strips.

  3. Wire wrapped jewelry - Wikipedia

    en.wikipedia.org/wiki/Wire_wrapped_jewelry

    Copper wire can be hammered quite thin. Brass wire is a little stiffer than copper, but it can be manipulated very easily. Sterling silver is soft enough to manipulate, but holds its shape well once it has been formed. Gold-filled wire is made by fusing a layer of 12-or 14-karat gold to a supporting material. Silver-filled wire is made in the ...

    The earliest gold artifacts were discovered at the site of Wadi Qana in the Levant. [13] Silver is estimated to have been discovered in Asia Minor shortly after copper and gold. [14] There is evidence that iron was known from before 5000 BC. [15] The oldest known iron objects used by humans are some beads of meteoric iron, made in Egypt in ...

    en.wikipedia.org/wiki/Electrum

    The name is mostly applied informally to compositions between 20–80% gold and 80–20% silver, but these are strictly called gold or silver depending on the dominant element. Analysis of the composition of electrum in ancient Greek coinage dating from about 600 BC shows that the gold content was about 55.5% in the coinage issued by Phocaea .

  9. Tumbaga - Wikipedia

    en.wikipedia.org/wiki/Tumbaga

    Tumbaga is an alloy composed mostly of gold and copper. It has a significantly lower melting point than gold or copper alone [citation needed]. It is harder than copper, but maintains malleability after being pounded. Tumbaga can be treated with a carboxylic acid, such as oxalic acid, to dissolve copper off the surface. What remains is a shiny ...
