Take a common chemical substance as an example, if its chemical name is "sodium chloride". "Chlorine" is one of the halogen elements, which is active and highly oxidizing. "Sodium" is also an active metal element, which reacts violently when exposed to water. The two combine to form "sodium chloride", which is the main component of our daily salt. Its chemical name not only indicates that the constituent elements are chlorine and sodium, but also implies the structural characteristics of the combination of the two by ionic bonds.
Another example is "ethanol", the word "ethyl" indicates that its carbon chain structure contains two carbon atoms, and the word "alcohol" indicates that the compound contains hydroxyl (OH) functional groups, revealing that it belongs to the characteristics of alcoholic organics. With this chemical name, its basic chemical structure and category can be known, and then some of its chemical properties and reactivity can be inferred.
There is also "calcium carbonate", "calcium" is a metal element, and "carbonate" is composed of carbon and oxygen elements in a specific ratio and structure. This name reveals that the substance is composed of calcium ions and carbonate ions, which is a common carbonate. Due to its chemical name, it can be known that under specific conditions, it can react with acids to form carbon dioxide gas and other properties.
Chemical names are like the identity cards of substances. Through precise word combinations, they convey rich chemical information of substances, allowing us to deeply understand the essence of substances. It plays a crucial role in chemical research, industrial production, and many fields of daily life.

Saltpeter, or potassium nitrate, was an important mineral in ancient China. It has been recorded in ancient books such as Tiangong Kaiwu. Its physical properties are as follows:
The appearance of saltpeter is mostly white or colorless crystals. It is like frost and snow, and it is brittle and fragile. Its crystal shape is often needle-like and columnar, and the aggregate is granular and lumpy. From the color point of view, pure saltpeter is as white as snow. If it contains impurities, it may be slightly yellow, gray, etc.
Saltpeter has a certain luster, similar to glass luster. It will be bright and reflective when illuminated by light. It feels dry and does not stick to the hand.
The solubility of saltpeter in water is quite unique. It is easily soluble in water, and when dissolved, it absorbs a lot of heat, which makes the solution temperature significantly lower. If you place your hand on the outer wall of the container containing the saltpeter solution, you can obviously feel the coolness.
Its density is slightly lighter than that of common stones, and when you hold it in your hand, you will feel lighter than ordinary stones of the same size.
Saltpeter also has the property of being easily decomposed by heat. Under high temperature conditions, saltpeter will undergo chemical changes and release gases such as oxygen. This property has a key application in ancient processes such as making gunpowder. As one of the important components of gunpowder, it provides the oxygen required for the combustion and explosion of gunpowder, so that gunpowder can react violently and play its role in military and civilian use.

"Tiangong Kaiwu" says: Mercury is mercury, which is also the liquid of cinnabar (mercury sulfide). Mercury is highly volatile, and it will fly in case of fire and disappear.
Mercury has many main application fields. First, in the field of medicine, in ancient times, doctors used mercury and mercury compounds as medicine. For example, in the refining of some medicinal pills, mercury is often an important raw material. The ancients believed that it may have the effect of prolonging life, curing diseases and saving people. However, due to the toxicity of mercury, such applications are often risky. Second, in the field of alchemy, mercury is often regarded as a key medium by alchemists because of its unique physical properties. They tried to use the properties of mercury to achieve the transformation of base metals into precious metals. Although there is no scientific basis for these attempts, mercury plays an important role in the development of alchemy. Third, in the mining and refining industry of Dan sand, mercury is used as a product of Dan sand extraction, and the mining and refining process are closely related. The bright red color of Dan sand is an important raw material for ancient pigments, printing mud and other important raw materials, and the extraction of mercury is also an important part of obtaining related products.
Of course, it needs to be understood that mercury is very toxic and extremely harmful to the human body, which can damage the nervous system, kidneys, etc. Although it has been used in many fields in ancient times, today, the use of mercury has become more cautious, and many traditional applications have been gradually abandoned due to health and environmental considerations.

In "Tiangong Kaiwu", there are many exquisite methods for brewing wine. The method of making rice is the first to select materials. Choose the best grain grain, or rice or wheat, all of which need to be full of particles and free of mold and impurities. Wash it clean, soak it moderately, and drain it before use.
When making rice, steam the grain and cool it to a suitable temperature. This is the key. If it is too cold, it is difficult for microorganisms to work; if it is not hot, it is easy to cause the growth of bacteria. When the temperature is right, sprinkle it into a special mother of Qu, which needs to be properly preserved and has good activity. Mix the mother of Qu with the grain well and seal it in an urn. The material of the urn is also exquisite, most of which are pottery urns, because it is breathable and can keep the environment stable.
After sealing, place it in a place where the temperature and humidity are suitable. If the temperature is high, it will be perishable, and if the temperature is low, the fermentation will be slow. Check it every day, and adjust the temperature and humidity in a timely manner. When it is fermented and mature, the resulting aroma will be tangy, and the quality will be available.
As for winemaking, use the prepared
B to put in the prepared raw materials. The raw materials are either millet or sorghum, and they also need to be carefully selected. Cook the raw materials, cool them, mix them with
B in an appropriate proportion, and inject an appropriate amount of water. Then ferment in the cellar, and the cellar tank needs to During fermentation, microorganisms act on the raw materials, and starch gradually converts into sugar, which is then converted into alcohol.
After fermentation, when taking the wine, there are also skills. The wine is slowly drawn out with special utensils. The first-flow wine has a little more impurities and can be treated separately; the middle-flow wine is clear and mellow, which is a good quality in the wine; the last-flow wine has a light taste and thin quality. After this careful production, a good wine can be obtained.

Mercury is highly toxic. Cinnabar also contains mercury, and realgar is also slightly toxic. When storing and transporting mercury, you must be very careful. If you are not careful, disaster will come.
Mercury is mobile and volatile. When storing, it must be tightly sealed. A cool, dry and ventilated place should be selected, away from heat and fire sources, to prevent it from evaporating rapidly when heated. The container used should be solid and well-sealed. Heavy glass or metal materials should be used. Do not use iron, because mercury will react with iron.
When transporting mercury, be more cautious. The packaging must be firm and reliable, and meet strict safety standards. During transportation, ensure smooth, avoid bumps and collisions, and prevent mercury leakage due to damage to the container. Transportation personnel also need to be professionally trained to be familiar with the characteristics of mercury and emergency treatment methods.
When storing cinnabar, attention should also be paid to moisture protection and sun protection, because its ingredients may decompose and change when exposed to light and heat. The same is true of realgar, and it should not come into contact with acidic substances, otherwise it will produce highly toxic gases.
When transporting cinnabar and realgar, the packaging should be tight, and labels should be made, indicating toxic and other warning information. The transportation environment should be suitable to avoid high temperature, humidity and mixed transportation with other chemicals to prevent dangerous chemical reactions.
Storage and transportation of mercury, cinnabar and realgar are all related to the safety of everyone and the well-being of the environment. They must not be taken lightly. They must strictly follow relevant norms and requirements to ensure that nothing goes wrong.
