Arsenic, or letter stone, is described in "Tiangong Kaiwu". The name of the living is Pi Huang, and the refiner is arsenic. The main use of arsenic involves many fields such as medicine, agriculture, and industry.
In the field of medicine, doctors in the past used it cautiously to treat and save people due to its toxicity. Although arsenic is poisonous, it can be used to treat certain diseases and diseases through fine processing and reasonable compatibility. In ancient times, physicians tried to use arsenic as medicine to treat diseases such as malaria and syphilis. Although new medicines and new drugs have been produced one after another, the historical value of arsenic in medical research is indelible. Some studies have also shown that arsenic may have a unique effect in the treatment of leukemia. After in-depth exploration in modern medicine, the active ingredients of arsenic are made into medicines to bring vitality to leukemia patients.
In the agricultural field, arsenic can be used as a pesticide. In the past, farmers used it to deal with pests. Due to its toxicity, it can repel many insects that harm crops and protect crop growth. However, due to its severe toxicity and long-lasting residue, arsenic is easy to cause soil and water pollution, and endanger ecological balance. Today, it is rarely used.
In industry, arsenic can be used to refine metals. For example, in the process of smelting lead and copper, arsenic can be used as a flux to help reduce the melting point of ore and improve the efficiency of metal refining. And in the glass manufacturing industry, an appropriate amount of arsenic can be used as a clarifying agent to remove bubbles in the glass liquid, making the glass more uniform and transparent. However, due to its toxicity, industrial use must follow strict safety regulations and environmental protection standards to prevent its escape from causing environmental pollution and personal injury.

The physical properties of mercury are as follows:


























In addition, it is the chemical activity of atomic molecules, which is composed of chemical compounds, such as flammable, but also capable of reacting to various substances, such as gold oxides, which can be produced from the original.
Mercury is produced from this, which is a common thing, but its general physical properties are essential in industrial and scientific fields, such as chemical synthesis, aerospace promotion, etc., all of which are made because of their unique properties.

Mercury is a highly toxic substance, commonly known as mercury, and is the only metal that is liquid at room temperature. Mercury vapor is highly toxic, and inhalation can cause serious damage to the human body.
Mercury has many special chemical properties. Its chemical properties are relatively stable, and it is not easy to react with oxygen at room temperature. However, when heated, mercury combines with oxygen to form mercury oxide. This reaction shows that mercury can react with active non-metals.
Mercury can form alloys with a variety of metals, namely amalgams. Active metals such as sodium and potassium can form amalgams with mercury, which is widely used in metallurgy and other fields.
Mercury salts also have unique properties. Some mercury salts, such as mercury chloride, are highly toxic and corrosive. And mercury salts can undergo redox reactions under specific conditions, such as the interaction of mercury chloride with some reducing agents, and mercury ions can be reduced to elemental mercury.
Mercury often exhibits unique oxidation state changes in chemical reactions. Its common oxidation states are + 1 and + 2 valence, and the properties of different oxidation state compounds are different.
Furthermore, mercury can react with sulfur-containing substances to form mercury sulfide. Mercury sulfide is highly stable. This property is often used for mercury pollution treatment and detoxification, so it can be converted into relatively stable and less toxic forms. < Br >
Special attention should be paid to the fact that mercury and its compounds are extremely toxic, and strict safety procedures must be followed when handling and using them to prevent serious harm to humans and the environment.

In the achievement of the combination of arsenic, it is important to pay attention to the important things.
The first priority is the fine selection of raw materials. Those who need to be mixed in the right place can ensure the profit of synthesis. The poor quality of its products directly affects the quality and quantity of arsenic. If the quality is not good, or the content is not good, the synthetic arsenic may not be in the right period, or there may be a lack of entry, which affects its effectiveness.
The environment of operation should not be ignored. It needs to be synthesized through good conditions. Due to the toxicity of arsenic, the synthesis process may be harmful and escape. If the pass is not good, the poison will accumulate, and the operator will be harmed and endanger his life. And the quality and quality of the environment also have an impact. It is advisable to keep the same level, and synthesize suitable parts.
Furthermore, the method of operation must be precise. The synthesis step is orderly and the proportion is precise. If the ratio of other ingredients is not the same, it may cause the synthesis to be very different. The heat and temperature also need to be controlled. If the heat is too fierce or insufficient, or too short, it will make the generation of arsenic unsatisfactory.
After the synthesis is completed, the storage of arsenic also needs to be careful. It is advisable to use a dense and solid container to prevent leakage. And it should be placed in a remote place and rarely reached by people. It is a clear warning to avoid others from eating and becoming a big problem.
In addition, the synthesis of arsenic requires attention. If there is a slight carelessness, the result will be unbearable. The operator must be very careful to ensure safety and effectiveness.

In today's market, if the incense of longevity is blue flame, its price varies depending on various reasons.
Cover this longevity incense, or take it from a rare place, its spiritual energy is full, and the spice produced is very unique. After being processed by a wonderful method, it is obtained that it is a special fragrance of blue flame. This incense is found in the mansions of high officials and dignitaries, and there are many people who seek it. One is to pray for blessings and prolong life, and the other is to show the honor of the family. Therefore, its price is high, or it is worth hundreds of gold or even thousands of gold, and it is not something that ordinary people can ask for.
Among ordinary workshops, there are also those whose longevity incense is blue flame. Its material may be slightly inferior, but the production also follows the ancient method, and the craftsmanship is still fine. The price of this kind of longevity incense, or tens of gold, is used for praying for a well-off family. Although it is not as luxurious as that used by the nobles, it also has its effect.
And the price of longevity incense varies with the supply and demand of the city. If it is a festive day, or when diseases are frequent, everyone is looking for incense to pray for peace and longevity, and its price will definitely go up; if the times are peaceful, the demand is slightly slower, and the price may fall.
There are incense shops that use clever marketing techniques to decorate the longevity incense with exquisite packaging and give it the name of auspiciousness, and its price can also increase by a few points. The price of the longevity incense in the well in the old city is roughly between tens of gold and thousands of gold, which is difficult to determine.
