Pyridine, 2,4-dichloro-3-iodo-

The chemical structure of this product is like an exquisite structure between heaven and earth, containing the wonders of nature. Looking at it, its structure is just like that cast by ancient gods, and all parts complement each other and are natural.
Its core structure is like the backbone of mountains and rivers, stable and solid. It is connected by many delicate atomic groups, like the fit of ancient mortise and tenon, which is tight and not bad. The atoms are connected by chemical bonds. This chemical bond is like an alliance of gold and stone, giving the structure toughness.
The part of the side chain is like a emerald willow to support the wind, which is agile and lively. Although light, it has a profound impact on the characteristics of the overall structure. Its length, curvature, and branching shape are not random, but follow the laws of nature and the power of creation.
Viewed from the spatial dimension, this structure may be symmetrical, and the symmetrical state is like the balance of yin and yang, giving people a sense of harmony; or it may have a unique distortion and folding, similar to the layout of the strange door's hidden armor, with hidden mysteries.
Its three-dimensional shape, or compact like a pearl, the atoms are tightly embraced, sharing the wonders of the electronic cloud, in order to reach the lowest state of energy; or it stretches out like a big roc, with all parts stretched out in an orderly manner, revealing its unique physical and chemical properties.
Such a chemical structure is the crystallization of the blending of nature and science. As mentioned in "Tiangong Kaiwu", it is not deliberately carved by human beings, but conforms to the principles of nature to achieve this exquisite structure and add a unique color to the material world.

The physical properties of this product are as follows:
Its texture is warm and moist, like suet condensation, and the tentacles are delicate and smooth, just like stroking brocade, without feeling of stagnation. Looking at its color, it is pure and flawless, white than snow, and faintly exudes a soft halo, just like the radiance of the bright moon. Its density is quite high, and when you hold it in your hand, it is quite weighty, but it does not lose its sense of movement, as if it contains the essence of heaven and earth.
Its hardness is also quite considerable, although it is not as hard as gold and stone, it is difficult to scratch ordinary utensils easily. Tried lightly with sharp tools, only shallow marks are left, which shows its toughness. And it has good toughness, which is not easy to break between bends, just like flexible tendons, which can bend and stretch.
Furthermore, the thermal conductivity of this product is also unique. Placed in the palm of your hand, it is cool at first, and after a while, it is suitable for body temperature, as if it can be integrated with the human body, conveying a warm and moist meaning, rather than cold and hard.
This product has unique physical properties, warm, white, dense, tough and suitable thermal conductivity. All kinds of characteristics blend with each other to create its extraordinary quality. Among all kinds of items, it is unique and shows the magic of creation in heaven and earth.

This product has a wide range of chemical properties, let me tell you one by one. It is stable, and under normal circumstances, it rarely reacts with surrounding substances. It is like a gentleman who is unflappable and stable as a rock. This characteristic makes it can be stored for a long time and is not easy to deteriorate.
Furthermore, its solubility is quite unique. In some specific solvents, it can dissolve quickly, just like ice and snow meet the warm sun, quietly disappearing into the invisible; in other solvents, it refuses to blend, just like oil and water, which are distinct. This difference in solubility makes craftsmen need to carefully select suitable solvents when blending and processing to achieve the desired effect.
And it is also flammable. When encountering an open flame or a hot topic, it will be like dry wood encountering a fire, instantly igniting a raging flame, releasing huge energy. Therefore, when storing and using, it is necessary to pay great attention to fire safety and keep away from fire sources to prevent unexpected disasters.
At the same time, this product is also corrosive to a certain extent. If you accidentally come into contact with certain materials, it will be like a sharp blade scratching paper, which will cause erosion and damage. Therefore, during operation, comprehensive protective measures must be taken to avoid hurting yourself and other items.
And its chemical activity cannot be ignored. Under specific conditions, it can chemically react with many substances to generate new products, just like magical magic, with endless changes. This property has opened up a vast world for its application in a wide range of fields, and has also given craftsmen endless room to create various materials they need by skillfully adjusting the reaction conditions.

This product is mainly used in various fields, and listen to me one by one.
In the field of war conquest, this product is quite effective. It can help soldiers to gain insight into opportunities on the battlefield, such as scouts probing the enemy's movements in the dark. It can rely on the characteristics of this product to more accurately grasp the enemy's virtual reality, provide a detailed basis for our march and formation, and help generals plan and move later, seize the upper hand in the battle situation, and improve the chances of victory.
It is also indispensable in places where traffic travels. When pedestrians shuttle between mountains and rivers and get lost, this product is like Sinan in ancient times, which can guide the direction and prevent them from getting lost. Boating in rivers, lakes and seas, in the face of complex water conditions, it can help boaters know the undercurrent of dangerous beaches in advance, avoid danger, and ensure a smooth and safe journey.
It is also very beneficial in the place where the mulberry is harvested. Farmers can predict the changes of the weather according to their characteristics, and sow, irrigate and harvest in a timely manner. For example, if you can know when the wind and rain are approaching, take precautions in advance to avoid damage to crops, help the harvest of five grains, and protect the foundation of people's livelihood.
It is also useful in the place where the workshop is built. When craftsmen create utensils and build palaces, this product can assist them in accurate measurement to ensure that the size is correct, making the created objects strong, durable, exquisite and beautiful.
In the observation of astronomical astrology, this product can also play a role. Stargazers can use it to better understand the changes of astrology, explore the laws of the operation of heaven and earth, and provide strong support for calendar revisions. In short, this product has significant applications in many fields and is a rare tool.

The method of making the blank of this utensil is to carefully select the clay and choose the one with fine and good viscosity. First, soak the clay with water to make it soft and moderate, and then knead the clay evenly by hand or with the help of simple utensils to remove impurities and bubbles, so that its texture is more uniform.
Next, according to the shape and size of the utensil, or use the method of disc building, that is, use mud strips to coil layer by layer and stack them up one by one to shape a rough outline; or use mud sheets to paste, cut the rolled mud sheets into a suitable shape, fit and splice, and build the prototype of the utensil.
There are also those who use the pottery wheel making method. The kneaded clay is placed on the pottery wheel, and the rotational force of the pottery wheel is used. With the cooperation of both hands, the clay is pulled and extended to shape a regular shape. In the process of drawing the blank, it is necessary to precisely control the force and speed to make the wall thickness of the utensil uniform and the shape is beautiful.
After the green body is initially formed, it needs to be carefully trimmed. Use bamboo pieces, mussel shells and other tools to scrape the surface of the green body to make it smooth and flat, and remove excess mud and defects. At the same time, the details such as the mouth edge and feet of the utensil are carefully carved to give it a delicate shape. < Br >
In this way, through multiple processes, rigorous and meticulous, a well-formed and solid body can be made, which lays a good foundation for subsequent decoration and firing.
