Feature of gold
The melting point of gold is 1064℃, and the specific gravity is 19.32. Therefore, the melting point and specific gravity are both higher than silver but lower than platinum. For 18K gold and 14K gold which comes to alloys containing other metals, its specific gravity will be lower than that 100% gold.
Main countries of gold production and the application of gold
Jewellery holds for about 70% of total consumption in South Africa, Australia, the United States and China. In Japan and Italy, 18K gold is preferred, in the UK, 9K gold, and in the United States, 14K gold is preferred.
