Shajin is also a type of gold. It is produced on the bottom of the river or a low -lying area. It is mixed with Shisha. It is a gold that was washed out after being was washed. At about 5%, and the gold I saw 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. Look carefully, the golden color is real golden yellow. . Differential gold adulteration:
1. Whether the gold has a white highlight, cut the gold bar or gold jewelry with ingredients, and observe the cut surface with a magnifying glass. Gold and cannot be fused together, indicating that the gold is mixed with 铱. 2, measure the proportion, first measure the weight of a pure gold bars with an balance, and then put the gold bars into the measurement 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.
