What is the difference between Vietnam and gold and gold? Shajin is also a type of gold. It is produced on the bottom of the river or a low -lying area, mixed with Shisha. It is a gold that was washed out after being washed. The gold content is low, and the gold content is about 5%, and the gold seen in China is all thousands of gold, with a gold content of 99.9%.
2, different degrees of hard and hard: Sand gold texture is hard, and Chinese gold is soft.
3, the color is different: At first glance, the color of the sand gold is golden yellow, and the golden color is real golden yellow.
The expansion information:
If discrimination of gold adulteration:
1, whether the gold has a white highlight, cut the gold bar or gold jewelry with ingredients, use Observing its cutting surface in the magnifying glass. If you see a white highlight, because the gold and the cricket cannot be fused, it means that the gold is mixed with crickets.
2, measured the proportion, first measure the weight of a pure gold bars with balance, and then put the gold bar in a measuring cup and flood the gold bar. Then put the detected gold bars in a measuring cup, whether the scale of the water rises or decreases. As long as it changes, it means that the gold bar is not pure gold. But if it is gold jewelry, this method is not applicable because there is air in gold jewelry.
3, real gold is not afraid of fire, put gold or gold jewelry on the fire for a while to observe its changes. Because the oxidation reaction occurs with oxygen in the air, the gold bars with insufficient purity will become gray; and the color of the pure gold will be red after the fire is baked. However, this method may be destroyed to jewelry.
Sand gold, English is a Gold Placer, which is produced on the bottom of the river or a low -lying area, mixed with stone sand, and washed out of gold. Sand gold originated in the mine, because the gold ore was exposed to the ground. After a long wind and rain, the rocks were cracked and cracked. Deposition is a gold -containing layer to form sand gold. The characteristics of sand gold are: different sizes of particles, large on the size of broad beans, small ones like fine sand, different shapes. The color is different due to the height of the formation. More than 90 % of them are red yellow, eight percent of them are pale yellow, and seven become cyan yellow.
