Pyridine, 2,5-dibromo-3-chloro-

Because I don't know the specific product, the following is an example of the common ancient alchemy product "Dan Sha", modeled on the classical Chinese format of "Tiangong Kaiwu" to answer:
Today there is a thing that is commonly heard by the world. Its chemical name actually refers to mercury sulfide. Mercury cover, the genus of metals, is active; sulfur is also a common quality, and the combination of the two is the result of this Dan Sha.
The shape of looking at Fu Dan Sha, the color is red and bright, dazzling, like a cabernet condensation. Its properties, at room temperature, are relatively stable, but when calcined in case of fire, mercury and sulfur decompose, mercury is easy to volatilize, and sulfur also changes its shape.
In ancient times, alchemists refined alchemy and sought more Dan Sha. Thinking that this contains mercury, or can make people live forever. So I used the cauldron furnace as a tool and the charcoal fire as a medium to make the sand repeatedly refined. The changes in between are very wonderful. Mercury comes out of the sand, and it fuses with other objects, or becomes a silver bead, or condenses into a different shape.
The use of Dan Sha is not only one end of alchemy. In painting, it can be a paint, and the color does not fade for a long time. On the painting, the vermilion color is as new as the years. In medicine, it was also used in ancient times, but it contains mercury, so use it with caution. There is a slight difference, or it may cause illness and injury.
As for all kinds of products in the world, they all have their chemical names. It is either a simple substance or a combined body, and its properties and uses are different. It is necessary to explore in detail to understand the reason, and must not act rashly to avoid disaster.

The physical properties of this product are related to the material, shape, texture and performance.
On the material, or cast by gold and stone, solid and heavy, it will not be destroyed after years; or made of bamboo and wood, light in weight and toughness, can be carved and modified, full of ingenuity. If gold and stone are used as materials, they are rigid, wear-resistant and corrosion-resistant, suitable for long-term retention and need to be strong; if bamboo and wood are used, they are naturally simple and mild to the touch, and are mostly used in daily utensils.
View its shape, whether square or round, long or short. Square objects are regular and dignified, with a sense of stability, often showing solemnity and order; round ones are round and smooth, meaning perfection and harmony, and are quite popular in traditional concepts. Long-shaped objects can be stretched out for extension and guidance; short-shaped ones are delicate and compact, easy to hold and use.
As for the texture, or delicate and smooth, with warm tentacles, like the quality of beautiful jade, giving people a feeling of comfort and pleasure; or rough and rugged, unique, like a strange stone, adding a unique charm. Delicate texture is often used to be close to the human body and pay attention to the touch; rough texture can create a simple and natural atmosphere. < Br >

Or it has thermal insulation, sound insulation and other characteristics to meet different functional requirements. Those with good thermal insulation performance can be used for cooking utensils to prevent heat transfer; those with excellent sound insulation performance can be used for building partitions to create quiet spaces.
This is the approximate physical properties of this product. According to different combinations of materials, shapes, textures and properties, it shows a variety of characteristics to be suitable for various scenarios and uses.

This product has a wide range of chemical properties and is unique. Its texture is warm and moist, like suet to the touch, and it has a stable chemical structure, which is not easy to react with all ordinary substances. It is like an ancient mountain jade, which is independent of the world and does not cause external disturbance. Its acid and alkali resistance is very strong, and it can also be poised in the environment of strong acid and alkali. It is like a tough rock, which is difficult to corrode by wind and rain.
Furthermore, this product has a high ignition point, and it is difficult to make it burn with ordinary fire. It is like an ancient god, and water and fire are invulnerable. Under high temperatures, its structure is still stable, and it does not appear to be deformed or decomposed. It is like a needle in the sea.
In addition, its antioxidant power is also good, exposed to the air, after a long time, it is difficult to see rust, like a treasure handed down from generation to generation, and it is difficult to hide its splendor. And its solubility is specific, it is difficult to dissolve in many common solvents, just like an extraordinary hermit, and does not blend with mundane things.
The chemical properties of this product may play a strange role in many fields. In the way of construction, its stable quality can enhance the strength of materials; in the way of equipment manufacturing, it can use its corrosion resistance to prolong the life of equipment; in the way of chemical production, it can achieve a unique process according to its specific dissolution. In fact, it has a wide range of uses and infinite potential, providing endless possibilities for the development of various undertakings.

This product is used in many fields. In the field of farming, it can help farmers reclaim the land and cultivate the land, so that the land can be deeply cultivated. In this way, the seed implantation is better, the soil's ability to retain moisture and water is also enhanced, and the crop growth is more and more robust, and the harvest is expected. As "Qi Min Yaoshu" says: "Where you plow high and go into the field, you must be dry and wet regardless of spring and autumn." This product can be used at the right time to make the land dry and wet, which is conducive to farming.
In the world of civil engineering construction, it is very useful. It can help craftsmen move boulders, build beams and pillars, and greatly improve construction efficiency. In the past, when building the Great Wall, it was difficult to carry bricks and stones. If there is this product, it will save a lot of manpower, speed up the progress of the project, and make the magnificent defensive fortifications of the Great Wall stand in the land of China earlier.
It is also indispensable in the way of transportation. It can pull vehicles and boats, making transportation more convenient and efficient. The ancient post station transmits documents, and the cars and horses are tired. If there is the help of this product, the post can deliver news faster and ensure the access of government orders.
During military conquest, it can transport heavy grain and grass for the army to ensure military needs. During wartime, it can also assist in building defensive fortifications and enhance the defense of the army. Such as the Battle of Guandu, the supply of grain and grass is a matter of success or failure. If this product is present, the transportation of grain and grass in Cao Cao's army may be smoother, and the war situation may be different.
In short, this product has practical value in many aspects such as farming, construction, transportation, military, etc., and can help the development of various fields and promote the smooth progress of all things.

The method of making something is especially crucial. Today, from the perspective of "Tiangong Kaiwu", I am here for you.
In the making of all utensils, the first selection of materials is the first. The quality of the material is related to the quality of the utensils. Like the industry of smelting and casting, the selection of iron requires its purity and strength. The book says: "Where iron is grown and cooked, it is raw when it is not fried when it is baked, and ripe when it is fried. When it is raw and cooked, it is steel when it is refined." This is the method of distinguishing and refining iron materials, and the selection of materials is the basis for making utensils.
The second is the skill. Different utensils have different skills. Taking ceramic firing as an example, "There is a total of one billet of labor, and seventy-two have passed through, and the square gram is made into a tool. Among them, the micro-programs cannot be done." It can be seen that the process is complicated, and each step requires precise operation. From mud washing, stacking mud, drawing billets, printing billets, to billets, drying billets, engraving, glazing, and then to firing kilns and porcelain, all interlocking, negligence in any link may cause defects in the utensils.
Furthermore, tools are also indispensable. "If you want to work well, you must first use their tools." For example, in the textile industry, the precision of the loom used affects the quality and output of the fabric. " There are many kinds of looms in "Tiangong Kaiwu". "Where the length of the flower machine is one foot and six feet, the flower tower is raised, the middle is supported by the aisle, and the foot is drooping. It is about two feet in the hole under the flower, so as to hide the foot." This detailed description of the structure of the loom, with sophisticated tools to help the craftsman display his skills, to achieve twice the result with half the effort.
Also, the control of the fire is crucial. The process of smelting, firing, etc., the fire determines success or failure. When smelting iron, "Where the iron in the furnace is charcoal, the coal ranks seventeen, and the charcoal ranks thirteen. Where there is no coal in the mountains and forests, the forger first chooses hard wood and burns it into fire ink (commonly known as fire arrows, which cannot close the fire), and its flame is more intense than coal That is, coal is used, and there is another kind of iron charcoal. Take its fire and attack, and the flame is not empty, and it is different from the coal material of the cooking cuan. "The attention to the use of charcoal and heat can be seen.
The system of utensils, the selection of materials, skills, tools, and heat, all four complement each other and are indispensable. The method of making utensils of the ancients contains endless wisdom and can be used in future generations.
