Gold is reputed to be the first metal discovered by man. It is the only natural yellow metal and because of this it became associated with the sun and gods. For centuries gold has been proudly worn as a sign of wealth and prosperity. An ancient gold coin retrieved from the ground after hundreds of years still maintains its condition and brightness. It’s nobility – resistance to corrosion is such that not only does it resist surface chemical change imposed by the weather – oxidisation causing tarnishing, but it resists attack from acids also. Hence its use for coinage. Gold is also a malleable metal, another factor for use in goldsmithing. Fine or pure gold is soft and therefore unsuitable for jewellery manufacture. Controlled by strict laws, quantities of different metals (parts) are mixed with gold to produce a suitable alloy for jewellery manufacture. The Cornish Tin & Gold alloy retains the 9ct gold purity and uses Cornish Tin from the ship that later became a wreck in the photo above, as a part of the other 15 metals added.
