1, color:
The steam emitted when gold is melted is yellow -green; its gold powder during the smelting process is usually brown; It is cast into a thin piece, and it can convey green light.
2, ductility:
is extremely strong. 1 ounce of gold can be pulled into 50 miles long, and its ductility makes it easy to cast and is a good choice for making jewelry. Gold is the strongest in the metal.
3, forgedness:
INO. It can cause extremely thin and easy to roll up. 1 ounce of gold can be hammered to 1 foot thick and 100 square meters of 4 million. The ancients hammed it into thin slices to decorate the temples and the palace. These can explain the flexibility and forgedness of gold.
