What is 916 kdm?

Answer 1

916 means How much of purity in your gold thats says in % . For an example. The pure gold is 24 carrot. We can't make any ornaments with pure gold. So the gold Smith add some percentage of copper to make ornaments. While you add copper the gold purity will be come less carrot. While we purchase 22 carrot gold ornaments that mean 22 carroty divide by 24 carrot the answer will be comes .916. That means in 1000 particle of gold added 84 particle of copper mixed and made ornaments. 1000/84 equal 916. 916 mean 22 carrots. 875 means 21 carrots, 750 means 18 carrots. The amount of copper mixed with your gold. The kdm is the shortform of kadmium. This cadmium chamical will help to join the ornaments and will get evaporate and will not stay with gold . Before cadmium technology Gold Smith are using powder flex to soldering the ornament and the powder flex wax will remain with gold weight. Hope you understand now with nannees Coolmeerawahab.
