As a precious metal, gold (Au, melting point 1,064°C) is surely one of the most fascinating materials. It is highly prized for jewelry and for financial investments in the form of bars or coins. Up to this point in human history, about 160,000 tons of gold have been mined throughout the world. It may sound like a lot, but this amount produces a cube with an edge length of only 20 meters. It is part of the service of biotecIasia, to give our customers access to the international markets for gold, silver, platinum with market information and competitive execution of purchase and sale orders.
