Because I don't know the specific product, the following is an example of "gunpowder". According to the classical Chinese format of "Tiangong Kaiwu", you can adjust it according to the actual product.
All kinds of wonderful things in the world depend on the power of creation and human ingenuity. Today there is a product called gunpowder, which is one of the four great inventions of China. Although its chemical name is not called in ancient times, according to today's chemical knowledge, the main ingredients are potassium nitrate (KNO), charcoal (C) and sulfur (S).
Potassium nitrate is hot and dry, and can help ignite and explode. In ancient times, the art of alchemy gradually evolved, and alchemists sought longevity pills, and occasionally obtained this wonderful change. Charcoal is light and porous, flammable and can burn quickly, and is the foundation of combustion in gunpowder. Sulfur is flammable, and it emits a peculiar fragrance when it burns, and it can also increase the explosive power of gunpowder.
These three are combined in an appropriate proportion, and after grinding and blending various processes, they are made into gunpowder. It is also a thing, and it is safe in peacetime. In case of open fire and impact, it will explode, and its power is amazing. Or in war, you can shoot guns, destroy strong cities, and defend against enemy invaders; or in festivals, you can make fireworks, brighten the night sky, and add joy and joy. The wonders of gunpowder can be described in words. It is actually a treasure of the combination of heaven and man. It has been passed down to future generations, and it has made great contributions.

This product has all kinds of physical properties. Its texture is solid, just like the solidity of gold and stone. When you hit it, the sound will be clear and bright, and the aftertaste will be long, like the sound of gold and stone. Its toughness is evident, and it is not easy to be damaged by external forces.
Look at its color, it is warm and lustrous, like ancient jade with light, restrained but not ostentatious, revealing an ancient and simple charm. Under the light, the light and shadow flow, adding a bit of agility.
Its density is moderate, it is handheld, and it has a sense of calmness. It is comparable to something not frivolous. Although it is heavy, it is not delicate, just like a proper balance, you can feel its texture when you play with it in your hand.
Furthermore, its thermal conductivity is unique. In case of heat without sudden temperature, there is no risk of burning your hands when you touch it; in case of cold, it is not quick to cool, and between grasps, the warmth still exists, as if it has the ability to adjust the temperature by itself, as if it is in harmony with people.
And the surface of this object is smooth like a mirror, rubbing it, delicate and smooth, without hindrance, like stroking spring water, like touching catkins, showing a warm state.
Its ductility is also good. With ingenuity, it can be slightly deformed, but it does not break. It is like a combination of toughness and flexibility, like a gentleman who can flex and stretch, combining rigidity and softness.
All these physical properties complement each other, giving this object a unique charm, making it stand out among all kinds of items and unique.

What are the main uses of this product? "Tiangong Kaiwu" has a saying: "The silk, hemp, fur and brown in the world have quality, so that the special face and color can still be used. I don't believe it if I say that the creation of things is not laborious." Although this statement is about dyeing, it can also be seen that the use of various products is important.
All kinds of products in the world have different uses. Take common utensils as an example, the main use of agricultural implements is to assist farming, cultivate the land, sow and harvest, so that the fields can be harvested, and the common people can be full. Such as Leiji, "Broken wood is for the trouble, rubbing the wood is for the trouble, and the benefit of the trouble is to teach the world", which plays a crucial role in the beginning of agriculture, and it is the fundamental tool for agricultural work. < Br >
Another example is textile appliances, such as spinning wheels. "The car has wheels, collars, strings, and coats. It is transported by the left and right sticks to each other, as the big and small wheels, so that the strings can be transported by themselves." Its main use is to spin silk, hemp strands and other fibers into threads, and then weave the cloth for the world to make clothes and cover the body. The formation of cloth and silk is related to people's livelihood. From the cocoon to the thread into cloth, the spinning wheel runs through the whole time, which is indispensable for the textile industry.
Looking at building materials, masonry and the like, "Where mud is used to make bricks, it is also necessary to dig the ground to identify the soil color, whether blue or white, or red or yellow, all of which are sticky but not scattered, and pink but not sand." The use of masonry is to build walls and houses, shelter people from the wind and rain, and create a place to live. From palaces and halls to ordinary dwellings, masonry and stone are the foundation, laying the foundation for living.
The use of products is related to people's livelihood, whether for clothing, food, housing, transportation, or for production and labor. They are all necessary for the operation of the world and human life. Different products, depending on their uses, play unique functions at all levels of society, and build a universal world together.

There is something today, and if you want to know the method of its synthesis, you can cover all the methods.
One is the method of choosing materials. Material is the foundation of things. If the material is not good, it is difficult to make a good thing. You must choose excellent materials to meet the needs of things. Such as casting swords, choose fine iron, and its quality is tough, so that it can become a sharp blade that cuts iron like mud. When choosing materials, carefully observe its nature, its quality, and its source, and do not let inferior materials mix in. This is the beginning of the synthesis.
The second is the method of applying art. Artists, the key to making things. Craftsmen practice skills, according to the shape and use of things, apply skillful skills. Or chop, or carve, or cast, or weave, each has its own way. If you cut jade, the craftsman uses sharp tools, according to the texture of the jade, and carefully crafts it, so that the jade becomes a beautiful tool. When applying art, focus on concentration, precise techniques, and proper priorities can be used to develop the wonders of things.
The third is the method of sequential order. Everything has its own order, and the combined thing is no exception. What to do first, and what to do later, there are rules. If the order is disordered, things will be difficult to achieve. If you build a house, build a foundation first, second columns, and then erect beams and tiles, and move forward in sequence, and the house will be solid. Follow the order and order to make things smooth.
The fourth is the method of harmony. All parts of things need to be coordinated with each other. Like the strings of the piano, the thickness and length are different, but they need to be properly reconciled in order to play a beautiful sound. When making things, make the proportions of the parts appropriate, the functions are coordinated, and the whole is harmonious and unified. Or adjust the color, or even the force, or suit the nature, so that the thing is perfect.
All these methods are essential for the synthesis of this thing. The craftsman follows them, using the heart as the guide and the hand as the tool, to make a fine thing.

When an utensil is in use, it is quite important to pay attention to all kinds of things, which are related to its effectiveness and longevity, and should be carefully reviewed.
First inspection. Before using it, you must carefully check the utensil, depending on whether it is damaged or cracked. If there is a flaw, or the use is not smooth, or even life insurance. If a boat is traveling on water, you must check the firmness of its cabin plate and the integrity of its masts, so that it can be safe in the waves; if the sword is in the hand, you must check the advantage of its edge and the strength of its handle, so that it can be used to overcome the enemy. If the utensil is in good condition, it is the foundation of use.
Next, be careful. According to the nature of the utensil and the rules of use, keep in mind the operation. Do not use brute force on delicate objects, and do not use rough and sparse treatment on precision instruments. For example, the piano and swords need to be fitted with the fingers before they can make a wonderful sound; when the crossbow is stretched, the size of the force must be moderate, and it can be reached. If it is not handled properly, it will be difficult to do its best, and it is easy to cause damage.
Furthermore, it is necessary to maintain it from time to time. The utensils after use should be properly maintained according to their quality and characteristics. Wooden ones prevent their decay, and metal ones protect their rust. Like ancient swords, they are often wiped with oil, hidden in a dry place, and remain as sharp as ever for a long time; the genus of calligraphy and painting must be placed in a cool and ventilated place, protected from dust and moisture, in order to maintain its color and texture. With proper maintenance, the lifespan of utensils can be extended.
And it should be well stored. When utensils are idle, the method of storage should also be appropriate. Large utensils should be stably placed to prevent them from being dumped; small utensils should be stored to prevent their loss. Fragile utensils should be padded with soft objects; perishable objects should be stored in suitable places. For example, the storage of porcelain, wrapped in rice straw or cotton wool, can be placed in a cabinet to ensure its safety; the storage of fresh fruits, according to their nature, may be hidden in a cellar, or hung in a ventilated place, can extend its freshness.
When utensils are used, they should be kept in public morality. Do not disturb people with utensils, and do not damage public utensils for self-interest. If the utensils are shared by all, use them to return to their places, and keep them clean so that others can use them again.
All these things of attention are the way to use utensils. If you do it, the utensils will be used for a long time and do their best, and it will be more beneficial to people's actions.
