Project at a Glance Contents on the CD ROM
  • While pure gold is yellow in color, colored gold can be developed into various colors.
  • These colors are generally obtained by alloying gold with other elements in various proportions.
  • To produce green gold, varying amounts of silver, copper, and cadmium may be alloyed in differing percentages to create a range of green gold shades.
  • Gold in pinks to reds requires varying amounts of copper and silver. Some gold colors, such as purple
    and blue, contain aluminum and iron, respectively.
  • These gold colors are much more difficult to produce but are stunning in appearance.
  • Certain colors may be limited to 10kt, 14kt, or 18kt. Generally white, rose, and yellow gold are available in all three karatages.
  • Research all necessary application equipment, material and development needs of the industry from concept and design to finished product in order to enable speedy introduction to the market of new coloured gold's and surface treated gold's.
  • Mixing in silver and copper is a bit of science-if too much silver is added, the gold will show a green tinge. On the other hand, mixing in too much copper will give gold a red tinge (so-called "rose gold").
  • Addition of nickel or palladium overpowers the distinctly bright yellow color of gold, producing what is known as "white gold."
  • Mixing other metals with gold produces a variety of colored golds, such as green gold , pale yellow gold , yellow gold, red gold, and white gold.
  • Rose gold is made by melting gold with copper which is naturally reddish in color.
