The softness of pure gold is enormous . It can be easily crush hands , scratching fingernail. However, in the manufacture of jewelry ornaments as required strength , it is alloyed with copper and silver .
What to know how much gold added impurities , the composition of these alloys shows sample . It indicates the number of parts by weight per 1000 parts of gold alloy.
