What is the value of gold?
The gold value is mainly due to rare. Compared with other metals, the total amount of gold stored on the earth is very small. For example, iron and aluminum are the largest metal in the earth, so these two things are not worthy, and silicon is the richest element of the earth, so sand (mainly consisting of silicon oxide) is the least valuable. The reason why gold is expensive is because it requires a lot of manpower and material resources in the mining process, that is, its production cost is very high, and compared with most metals, its number is scarce. Therefore, gold has become an asset. The rareness of gold makes gold very precious, and the stability of gold makes it easy to save. Therefore, gold has not only become human material wealth, but also an important means for human storage of wealth. Therefore, gold is favored by humans.

1. Look at the color. The color of gold is dark yellow. If it is not pure, it is pale yellow. The larger the purity, the darker the color. Red and yellow purity is above 95%, pale red and yellow purity is 90-95%, pale yellow purity is 80-85%, blue-yellow purity is 65-70%, blue and white purity is only 50-60%, yellow and white purity is less than 50 than 50 %.
2. Look at this mark. Gold is the finished product produced by the state in accordance with the production standards. At the same time, there is also a mark that labels the number of gold, such as 18K, 24K, etc. , But the low color system does not mark this logo, so the basic color that can be marked is high color. Sometimes you need a magnifying glass to check the mark to distinguish the truth.
3. Real gold is not afraid of fire. That's right. Burn the gold red with fire, and then observe what color the cooled gold is. If it is still the original golden yellow, it means that the purity of gold is relatively pure. If it is dark black after burning, it means that there are flaws in it, which may be fake gold ornaments.
4. Sound. Gold also has its own metal sound. Generally, the higher the purity, it can make a slap sound on the ground. If it is impure, it will make a dull Ding Ding. However, this experiment needs to be more obvious in a relatively quiet environment. There are certain limitations.
