This metal has been known since prehistoric times Gold is a soft metal with a characteristic yellow color. It is the most malleable and ductile of any element. It is unaffected by air, water, alkalis and acids, with the exception of "aqua regia", HNO3/HCl. The fact that it is chemically unreactive means that it is often found in its natural state. It is a good thermal and electrical conductor and has excellent reflective properties to both light and infrared. It has an abundance in the earth's crust of 0.0011 ppm. Most of the metal is retained for use as bullion reserves, but some is used within the electronics and jewellery industries, where it is frequently alloyed with other elements to improve the mechanical properties of the metal (e.g. copper and silver). Other uses for the metal are as a heat reflecting coating for glass as well as as a decorative medium.

Please note that this item is excluded from reductions or special offers. 

Using finest materials, each density cube was lapped to 10x10x10mm by a famous company especialized in noble metals. Each one separately ground and polished it represents the theoretical density of the respective element by its weight. The weight is not affected by the laser inscription. Information such as element symbol, name and density is durable burned at the surface. Altogether 25 elements are planned in a complete set in a wooden case.
The cube in the picture is without laser engraving. You will receive a finished and engraved cube!
