Copper Sphere- 290 g - (1)

The name derives from the Latin spoken as aramen (a word already attested in 950) for late aeramen, a derivative of the Latin word aes, which means 'copper' or 'bronze,' names preserved in other Indo-European languages.
Copper is the metal that humanity has used for the longest time: objects made of copper dating back to 8,700 BC have been found.
Copper is a pinkish or reddish metal with very high electrical and thermal conductivity, surpassed only by silver; it is highly resistant to corrosion due to a thin adherent patina that forms spontaneously on the surface, initially brown in color and later green or bluish-green, and it is non-magnetic. It is easily workable.
