His beautiful color - rare among metal - and his wonderful glow are most likely the first qualities that have attracted people to gold since prehistory. And using it, they found the weather and other qualities, thanks to which they valued more, for millennia. Until today, gold continues to be highly valued in both art and science because of its remarkable properties. At first, it was perhaps that could be valued for easy processing: from pieces of native gold (found as such) could be reached fairly quickly ornaments: gold can be processed easily, even cold, even with of primitive tools. This property, called malleability, made possible to obtain the most beautiful jewelry, but also the most sumptuous gilded decorations. 
Gold is very malleable and ductile of the metals . Due to the extraordinary malleability (ability to withstand high compressive forces, which manifests itself can be stretched into sheets without breaking), gold can be beaten by a fine foil incredible: a single gram is obtain a thin film, translucent, with an area of 1 square meter! Ductility is seen in the possibility of being drawn into wires - the wires that can be obtained are thinner, the metal is more ductile. Delicate gold jewelry wire, sometimes true gold wirelace, can be made because of metal ductility. Gold is one of the most dense metals - or of the hardest, as they say in familiar language, is heavier than lead, which has a density of 11 340 kg/m3, while gold is 19 300 kg/m3. (The heaviest metal, the highest density is osmium - 22 610 kg/m3).Read more: http://www.bukisa.com/articles/584204_gold-and-its-amazing-features#ixzz1c6sJdjKi
