Mercury is a highly toxic substance, which is very harmful to the human body and the environment. Mercury and copper, tin and other metals are made into amalgam such as copper amalgam and tin amalgam, which played an important role in many fields in ancient times.
In alchemy, amalgam is of great significance. Ancient alchemists believed that by refining elixirs, one can achieve immortality, and mercury and its alloys are often important raw materials. Due to the special chemical properties of mercury, it can form amalgams with various metals. In the process of alchemy, alchemists use amalgam to change the shape and properties of substances. For example, when refining some elixirs, mercury and other metals are made into amalgam, and then through complex refining processes, they hope to obtain elixirs with magical effects. Although there is no scientific basis for this from a modern scientific point of view, amalgam was an indispensable item in the culture of alchemy at that time.
In the field of ancient metallurgy, amalgam was also used. The ancients found that mercury can form amalgams with precious metals such as gold and silver, and gold and silver can be extracted and refined with this characteristic. For example, in the process of gold mining, mercury and gold can be used to form gold amalgams. The gold-bearing ore is mixed with mercury, and the gold dissolves in the mercury to form gold amalgams. Then the mercury evaporates by heating and other means to obtain higher purity gold. This method was quite commonly used in ancient gold and silver smelting, helping the ancients to improve the efficiency and purity of gold and silver and other precious metals.
Furthermore, amalgam also has a place in the production of ancient utensils. For example, in the production of ancient mirrors, tin amalgam was often used. After tin and mercury were made into tin amalgam, it was applied to the back of the bronze mirror to enhance the reflective effect of the mirror. This process enabled the ancient bronze mirror to better image, meet people's daily care needs, and to a certain extent reflect the superb production skills of the time.

"Tiangong Kaiwu" reports that mirabilite minerals do have many applications in different fields.
In the salt industry, it can be used to remove impurities in brine. When sea brine cooks salt, its brine often contains impurities such as calcium sulfate, which affects the quality of the salt. Putting mirabilite into it can precipitate impurities such as calcium sulfate, obtain pure brine, and then cook high-quality table salt.
In the field of medicine, mirabilite has the effects of diarrhea and accumulation, moisturizing dryness and firmness, clearing away heat and reducing swelling. It is suitable for real heat stagnation, dry stool and other diseases. Taking the empirical evidence of typhoid fever Yangming Fu as an example, the patient's hot topic, delirium, and stool are blocked. At this time, mirabilite can be used in combination with rhubarb, and mirabilite can be used to soften and moisturize dryness and diarrhea, so that dry shit can go down and evil heat can be vented.
In metallurgy, it can be used as a flux. When smelting metals such as copper and lead, the addition of mirabilite can reduce the melting point of the ore, promote the ore to melt at a lower temperature, improve the efficiency of metal smelting, and reduce energy consumption. And it can react with the veins in the ore to generate slag, separate the metal from impurities, and improve the purity of the metal.
In the printing and dyeing industry, When dyeing fabrics, adding an appropriate amount of mirabilite can improve the dye uptake rate, make the dye better adhere to the fabric fibers, dye more uniform, firm, and brighter color.
In the papermaking process, mirabilite also plays a role. During pulping, mirabilite can participate in the preparation of cooking liquid, help fiber separation, improve pulp quality, and make paper tougher and flatter.

There are the following general precautions for the use of mercury chemical compounds:
First, it is necessary to be in the right place. It is a good place to be dry and pass through. This is because mercury chemical compounds have many properties. If they are in a humid place, they are easily invaded by water vapor, causing their properties to be poor. If they are not good, they will be scattered after use, which will not hinder the operation, and they may be toxic and endanger the human body.
Second, be careful when using utensils. It needs to be filled with special crucibles, tripods and other utensils. The crucibles and tripods used must be dyed, and the materials can withstand high temperatures, and the biochemical reactions of mercury chemical compounds will not be affected. No, the mixing of the equipment, or the invasion of the material, so that the loss of sex, the effect of shadow.
Third, the proportion of precision control. When used in combination with mercury and Dan chemical, the proportion of each ingredient is high. If there is a slight deviation, the result of the reaction will be large. Or it will become a pill, or the resulting thing is toxic and harmful, and it cannot be used. If mercury is too toxic and heavy, and too little condensation, it will be ineffective.
Fourth, the heat is appropriate. The use of fire is high, and the size and duration of the fire are determined. At the beginning, boil slowly with a slow fire, so that the material is melted and its essence is refined; with a fierce fire, promote its synthesis into pills. If the heat is not hot, the fire will not melt, and the fire will not disperse, and the work will be one.
Fifth, it is necessary to prevent damage. During operation, cover your mouth and nose with a cloth towel to prevent poison inhalation. Hands also need to wear leather gloves to avoid direct contact with skin chemicals, because mercury chemicals are often toxic. If you are not careful, they will be poisoned into your body, and your life will be seriously endangered.
Therefore, when using mercury chemicals, you need to be careful in order to obtain their effectiveness and avoid their harm.

There are all kinds of side effects of the armor-like substance. First, this substance may cause physical discomfort. Those who take it often feel colic in the abdomen, such as insects and ants biting, tossing and turning and restless, and even vomiting and diarrhea, and vitality is seriously injured. Second, it may cause mental confusion. After people use this armor-like substance, their minds gradually lose clarity, and they often experience hallucinations, as if they are in an illusion, seeing all kinds of strange things, acting crazy, forgetting where they are and what they do. Third, in the long run, there may be a risk of leaving behind the bloodline. Make the family bloodline disordered, and the children born are either weak and sickly, or have a strange appearance, laying the root for the family's continuation. Fourth, it may trigger the change of the energy of heaven and earth. When many armor-like substances are in one place, it may change the color of the wind and clouds, the aura field will be disordered, the surrounding plants and trees will wither, the water source will deteriorate, and one side of the water and soil will be affected, causing life to be wiped out. In short, the secondary use of this armor-like substance should not be underestimated, and it should be used with caution to avoid endless disasters.

What Wen Jun inquired about is the market price of suet jade. Suet jade is warm and delicate, like suet condensation, and has always been a treasure in jade. Its price is famous for being high, but the price of suet jade needs to be reviewed many times.
First of all, the material of suet jade is excellent, and the market price per gram can reach thousands or even tens of thousands of yuan. If this suet jade is made of pure suet jade, its price must be high. However, the difference in material purity, color, and texture can all be different.
Second, on the craftsmanship, sheep jade is an ancient ritual vessel, and its carving process must be very delicate. If the jade retains the exquisite craftsmanship of the original artifact, the shape is simple and elegant, the lines are smooth, and the decoration is exquisite, its artistic value and market value will also be greatly increased. On the contrary, if the craftsmanship is rough, the price will be limited.
Furthermore, consider its age and origin. If the jade has an exact age to be tested, and the inheritance is orderly, it has a profound historical and cultural heritage, and is valued by collectors, the price can also be viewed.
Overall, if the material of the jade is pure, the craftsmanship is exquisite, and the age is long and the origin is clear, its market price may reach one million or even higher. If the material, craftsmanship, age and other factors are insufficient, the price should be reduced as appropriate. It is difficult to generalize the facts, and it is necessary to ask a professional jadeite person to scrutinize it in detail in order to obtain a more accurate market price.
