The chemical properties of this product are as follows:
This product is peaceful in nature and is not easy to change violently with many common things. Under normal conditions, it is in a stable state, just like a quiet lake that stops water and does not make waves. In an ordinary warm and dry environment, it seems to be a person who is not alarmed by changes, and it is not easy to change its properties. It does not burn or explode, and exists safely.
In case of water, it can slowly blend, like spring rain moisturizing mud, quietly turning into one, and there is no hot image, no dazzling light, and no pungent smell. It is like a natural combination.
As for acids, common dilute acids, when they meet them, the reaction is slight, just like a breeze blowing willows, moving slightly and stopping. When encountering strong acids, although there is a reaction, it is not violent and violent, and it seems to be in a state of softness and rigidity, step by step, not comparable to an instantaneous explosion.
When encountering alkali, it can also respond to it, but the reaction process is observable and controllable, and there is no abrupt change or danger.
For most common salts, it is like a gentleman's friend, not interfering with each other, and can coexist without dispute.
This product is chemically stable, and it can be stable in many common chemical situations. It rarely causes unexpected changes. It is like a calm and responsible person who keeps its original state in the midst of complicated things and is not easily disturbed by foreign objects.

The physical properties of this product are as follows: its quality is firm and dense, like the quality of gold and stone, although it is difficult to be damaged through wind and rain. The color is quaint and simple, or it is dark and clear, or it is warm and moist, and it has a simple and elegant charm. When you touch it, you feel its warmth and moderation. You can't feel its heat when you touch it in summer, but you can't feel its cold when you hold it in winter. It seems to be in harmony with human body temperature. Its weight is also, more common things are heavy, placed in the palm of your hand, quite a feeling of falling hands, showing its thick texture.
And its sound is also, when you hit it lightly, the sound is clear and long, echoing in the room, like the sound of a dragon and a phoenix, and the aftertaste is curling, which is endless in the ears. The light transmittance is also unique. Under strong light, it can be seen that its internal texture is looming, with strands of silk, like mountains and rivers, and like clouds and waterfalls, which is wonderful.
In addition, its ductility is also good. Although the quality is strong, it can be beaten and forged by skilled craftsmen to form thin filaments without losing its toughness. The wear resistance is also excellent. After long-term rubbing, the surface is still as smooth as before, with few marks. These physical properties make the product unique, and it is unique among all utensils.

What is the main purpose of this product? I will imitate "Tiangong Kaiwu" to answer in the format of ancient texts.
Looking at all kinds of utensils in the world, each has its own use, and this product is no exception. Its use is quite extensive, first in the field of production and manufacturing. In the workshop, it can help the craftsman to make the production process more exquisite and meticulous, and the quality of the finished utensils can be improved. If woodworking carves wood, this product can assist its accurate measurement, so that the lines are straight and the angle is correct. The wood made may have practical performance, or become a beautiful artifact, all rely on this product.
Furthermore, it is also indispensable in the construction of buildings. To build a building hall, you need to determine the orientation and measure the height. This product can help craftsmen to see clearly, ensure that the base is stable and the structure is balanced. Whether it is rammed earth to build a foundation, or beams to lay tiles, it can be used to determine the size, making the building sturdy and durable, and it will not fall over the years.
In daily life, this product is also very useful. Merchants in the market measure goods to ensure justice and fairness in transactions, and will not be short of weight. Farmers in the field can plan their fields according to them, and rationally lay out crop planting in order to seek a good harvest.
As for the army, the use of this product cannot be ignored. When marching, you need to inspect the terrain and distinguish between near and far. It can provide generals with accurate information to help them plan their strategies. When marching, you can know the dangers of mountains and rivers, set up camp and find suitable places, and you can better grasp the fighter jets during battle. Victory.
In short, this product plays an important role in all kinds of affairs, or helps work, or ensures fairness, or is related to safety. It is an indispensable thing in the world.

There are many ways to make this product, each with its own subtlety, and each has its own advantages and disadvantages in different situations.
One is the ancient technique of tempering. Select the best materials, after many washes, remove their impurities and retain their essence. The latter is placed in a special furnace, and the fire is controlled by a secret method. The temperature and length of time are determined. When it melts like flowing gold, pour it into a mold, and quickly quench it with cold water to make the texture firm. The material made by this method is pure in texture and tough in character. However, it is time-consuming and laborious, and cannot be done by non-skilled people.
The second is the method of fusion and harmony. Combine all kinds of materials and match them in precise proportions. First, part of the fusible material is melted in the kettle, and when it is liquid, other materials are gradually added. At the same time, special equipment is used to keep stirring to make it uniformly fused. This process requires close attention to the fusion state, and timely adjustment of the heat and stirring speed. In this way, the combined material has uniform performance and can be adjusted according to the needs of the characteristics. However, the proportion control of the material and the operation skills are quite high.
Third, there is a method of layered composite. Take materials with different characteristics and lay them in layers according to the order of design. Or use special adhesives to make the layers tightly bonded; or use high temperature and high pressure to make them penetrate and fuse with each other. This method can give full play to the strengths of each layer of material, so that the product has a variety of excellent characteristics. However, the requirements for process accuracy and equipment are very high, and a slight error will affect the overall quality.
These three methods of synthesis have their own advantages. The ancient method of tempering heavy materials is pure and tough in texture; fusion is good at performance deployment and uniformity; layered composite is better than the comprehensive advantages. In practical application, choose carefully according to product requirements, material characteristics and process conditions.

There is something today, and the price of it in the market cannot be determined quickly. The change of prices often varies with time, place, supply and demand.
The variety of states in the city of Guafu, in the past, things were rare and expensive, and things were abundant and cheap. This is also common sense. If things are in their prime, everyone competes to sell them, and they are better than the market. The price may be low, or it may be between the same and the third pass. When there is a stock of goods at that time, merchants want to sell them quickly to make a profit, so they have to reduce their prices greatly to attract customers.
And its time-shift, or when the weather is not going well, production is difficult, and there are few people who live, and there are many people who want it. At this time, its price must be high. Or to the five or seven passages, it is also unknown. The cover is in short supply, everyone is competing to buy it, and the price is soaring.
There are also places near and far, and dangers on the way, which are also related to the price. If the goods are nearby, the freight is saved, and the price is low; if they are transported from a distance, they involve mountains and rivers, and the cost is quite high, and the price is high.
And people's likes and dislikes, and changes in fashion, can also be animal prices. If this thing is suddenly liked by everyone, and it is popular for a while, although it is cheap, the price will also rise sharply; if the wind has passed, everyone dislikes it, and although it is good, it is difficult to sell, and the price will be low.
Therefore, in order to know the exact price of this object, it is necessary to carefully observe the order of time, the similarities and differences of place, the situation of supply and demand, and the change of fashion, and comprehensively weigh it to obtain its approximate price range.
