In "Tiangong Kaiwu", the main uses of mirabilite are many.
Mirabilite is one of them used to help make salt. When boiling salt, there is a bitter taste in the brine, and the addition of mirabilite can precipitate impurities in the bitter taste and improve the quality of the salt. Due to the reaction between mirabilite and impurities in the brine, the impurities condense and settle. This is an indispensable part of the salt cooking process, making the salt produced purer and better taste.
Second, it has significant functions in the field of medicine. Mirabilite has the effect of laxative, moisturizing dryness and firming, clearing fire and reducing swelling. Doctors often use it to treat symptoms such as heat stagnation, abdominal distension and pain, and dry stools. Because it can promote intestinal peristalsis, increase intestinal moisture, and make dry stool easy to discharge. And mirabilite can be used externally to reduce swelling. For the beginning of carbuncle sores, mirabilite can be applied externally to clear away heat and reduce swelling and relieve local swelling and pain.
Third, it is also used in leather manufacturing. In the leather tanning process, mirabilite can be used as a tanning aid. It can help leather absorb tanning agents, make leather softer and tougher, and at the same time enhance the corrosion resistance of leather, prolong its service life, so that the leather products made are of good quality and durable.
Fourth, it also plays a role in glass manufacturing. As a flux for glass raw materials, mirabilite can reduce the melting point of glass raw materials, making various raw materials easier to melt and mix evenly, thereby improving the quality and production efficiency of glass. During the glass firing process, mirabilite participates in a series of physical and chemical reactions to improve the properties of glass, such as transparency and hardness.

The combination of mercury is related to all kinds of delicate methods. If you want to make amalgam, the method is also complex. As for the combination of lead and mercury, it is especially important to the ancient alchemists, and it is related to the secret of longevity. Many ancient books have written it.
Mercury, the sexual flow, the body is clear, the method of combined refining, the first heat. When simmering slowly with a gentle fire, so that its nature is gradually tamed, so that it will not run away. In the cauldron of alchemy, put lead under it, cover it with mercury, and fill it with a tool of Tugui, sealed tightly, so that it will not be deflated. Burn with charcoal fire, the fire should be gentle at first, like the warm wind of spring, slowly drying it, so that the lead gradually melts, and its liquid is like golden waves surging. When mercury meets the heat of lead, it gradually becomes one, and this is the sign of the first combination.
There are also those who use medicine to introduce mercury. Take all kinds of gold and stone medicines, such as sulfur, realgar, etc., and study them into fine powder, which is combined with mercury. Sulfur, a pure yang thing, has a strong nature, and can make mercury cold. First put sulfur in the furnace, fry until the smoke is exhausted, and the color is like gold, then put mercury in it, and smash it with pestles and mortars to make it even. Set it on the fire, fry it quickly with a fire, and wait for it to boil, turn it to a slow fire, until it condenses like a paste, which becomes an amalgam.
Furthermore, mercury is synthesized by water. In a large urn, fill it with clean water, throw lead blocks into it, and then drop a little mercury and stir it. Mercury likes water, and lead can sink to the bottom of the water, and mercury will be attached to lead when it encounters it. After a long time, mercury is attached to lead, and it is taken out and dried, which is the combination of mercury and lead. However, this water method, especially the water quality is clear, and there must be no miscellaneous substances, otherwise the synthesis will not be possible.
As for the combination of other minerals and mercury, there are also different methods. Or lead it with magnets, or line it with mica, all need to follow its physical properties, follow its yin and yang, in order to form its alloy. Ancient alchemists spent their entire lives studying this path. Although there were many absurd ideas, they also had a lot of accumulated experience, which could serve as a lesson for future generations.

Mercury is the most yin and the most spiritual. Its shape is like water, its color is like silver, and it is in a flowing state at room temperature. It is like water rather than water, and has a metallic luster, so it is also called mercury.
Mercury has a high density, heavier than ordinary things, and can often fall when placed on top of other things. Its boiling point is low, about 357 degrees Celsius, and it is easy to turn into a gaseous state when heated. It drifts into invisibility and is elusive. And mercury vapor is toxic. If inhaled, it is easy to cause damage to the viscera and confusion.
Mercury has many characteristics in electrical conductivity. Although it is a metal, its electrical conductivity is slightly different from that of common metals. Under certain conditions, its electrical conductivity is very subtle.
In addition, the chemical activity of mercury is also considerable. It can form an alloy with a variety of metals, and this alloy is called an amalgam. The properties of amalgam vary depending on the metal involved, or they are tougher or have different physical characteristics.
Mercury often exhibits unique behaviors in chemical reactions. In case of strong oxidizing agents, it can be oxidized, and the valence of the compounds changes. The colors and properties of its compounds are different, or they are dazzling, or they have different chemical activities.
However, the many characteristics of mercury require caution when using them. Due to its toxicity, when operating, it is necessary to strictly follow the procedures to prevent its leakage and avoid endangering human health and the surrounding environment. The world should weigh the pros and cons of mercury, and use scientific methods to control this spiritual thing, so that it can benefit the world, not the world.

In today's world, business conditions change, and the price of the things in the market depends on various factors such as changes in supply and demand, the cost of materials, and the value of work. As for "What is the market price of 5-Zhou Laojiao 2-Class A wine?", if you want to know the price, you should carefully observe the market situation.
The quality of the wine is high, the essence of the brewing is high, and the amount of materials it takes to make is a lot. The needs of the city are also different, either because of festivals and banquets, or for collection and tasting.
When the supply of the market is sufficient, but the demand is not full, the price may be slightly flat. If the merchants want to sell their goods quickly, they will not be stagnant, so they will reduce their prices to attract buyers. However, if it is a festive day, people compete to buy it for relatives and friends, or the attention of collectors, and there are many people who want it. However, the stock in the city is limited, and the price must go up.
And the cost of materials is also related to the price of wine. If the grain of wine is made, the price will rise or fall due to the abundance of age and the vastness of the land. If the grain is expensive, the cost of brewing will increase, and the price of wine will also increase. On the contrary, if the grain is low, the price of wine may drop slightly.
Furthermore, the value of work is also an important factor. Class A wine, the brewing process is complex, requires good craftsmen and craftsmen, and the cost of brewing with heart is not light. If the value of work is expensive, the price of wine will have to change.
Therefore, if you want to know the market price of 5-Laojiao 2-Grade A wine in the city, you can get a rough idea by carefully examining the supply and demand situation and the cost of materials and work. However, the market situation is changeable, and the price also changes from time to time, so it cannot be generalized.

Mercury storage and transportation are related to life and livelihood, and must not be ignored. Mercury is extremely toxic, and in the storage environment, it must be selected in a remote, cold and dark place, and the utensils must be seamless to prevent its escape. If mercury leaks into the ground, cover it with sulfur quickly, so that it can be synthesized into non-toxic mercury sulfide, otherwise the mercury gas will be diffused, and if inhaled, it will hurt the internal organs and damage the mind.
As for the transportation of mercury, it must be filled with thick vessels, surrounded by soft objects to prevent it from being damaged by shock. Escorts should be aware of its hazards and prepare first aid equipment. On the way, do not approach many people, and avoid fire and high temperature places to prevent mercury from vaporizing due to heat and harming everyone.
"Tiangong Kaiwu" says: "Mercury, its gas is close to fumigation, and sulphur melts." This is the wisdom of the ancients, and the storage and transportation of mercury follow this path. Where mercury is stored, sulfur is often placed for emergencies. When transporting, strictly follow the ancient laws and be cautious.
Mercury is used as a thing, although it is available in industry, medicine, etc., it is more poisonous than tigers. If there is a slight mistake in storage and transportation, it will cause endless disasters. Therefore, those who work in it should have a sense of awe and be careful to abide by regulations, so that they can keep safe and secure, and never cause unexpected disasters due to temporary convenience.
