What is the main purpose of this product?
What are the main users of this product? "Tiangong Kaiwu" has a saying: "The silk, hemp, fur and brown in the world are all of quality, which makes it possible to have a special face and different colors. I don't believe it if I say that the creation of things is not laborious." Husband dyes, so the color of things is changed.
Ancient dyeing, the things used are mostly grass, wood and ore. Dyeing it with grass and wood can get a soft color; dyeing it with ore can get a heavy color. It has a wide range of uses, first and foremost in clothing. People's clothes, they want them to be fresh and pleasing to the eye, and the colors are different. From the crown of the emperor to the regular clothes of the common people, they all rely on dyeing to make their beauty. "Book of Rites · Jade Zao" says: "Clothes are regular color, and clothes are For those with normal colors, blue, red, yellow, white, and black are also used. Dyeing them as clothes is different from the noble and lowly grades.
The second is used for the decoration of utensils. Ancient lacquerware and ceramics are mostly dyed and painted. Dyeing their utensils makes the patterns distinct and increases their beauty and value. Such as the painted lacquerware of the Warring States Period, colorful and exquisite craftsmanship. Drawing patterns such as dragons and phoenixes and cloud patterns in dyed colors is lifelike, showing the aesthetics and skills of the time.
Furthermore, it is also useful in calligraphy and painting. Paper silk for calligraphy and painting, or dyed in light colors, makes it simple and elegant. Ink and dyed colors contrast each other to create a unique artistic atmosphere. And the color of pigments also depends on the dyeing method, or natural pigments are taken, dyed and processed, and used in the creation of calligraphy and painting. It has been passed down through the ages, and there are many contributions to dyeing.
It is also dyed in fabrics, which can make them strong and durable. The specially dyed fabrics can resist wind, rain and insects. Such as the sails of ancient warships, dyed with tung oil and other things to make them tough and waterproof and ensure the safety of navigation.
All of these can be seen in the main use of this product. It is indispensable in clothing, utensils, calligraphy and painting, fabrics, etc., adding gorgeous colors to life and art.
What are the chemical properties of this product?
The chemical properties of this product are various, and each has its own unique features. It is stable, and under normal conditions, it is difficult to react violently with other things. It is like a mountain hermit, content with its own state, and not easily disturbed by the outside world. If placed in an ordinary air environment, it is difficult to see significant changes after a long time. This is one end of its stability.
However, when it encounters a specific thing, it shows a lively state. When encountering a strong oxidant, it is like dry wood meeting a hot fire, which instantly triggers a violent reaction, or generates heat or emits light, as if the hidden energy is released at one time. The intensity of this reaction can cause great changes in the form and properties of matter, which is really the wonder of its chemical properties.
Furthermore, its solubility is also a major characteristic. In some solvents, such as fish in water, it can dissolve quickly and disperse evenly, as if it is integrated with the solvent, indistinguishable from each other. In other solvents, it is like oil and water, distinct and never blend. This property is influenced by many factors such as solvent type, temperature, pressure, etc., like a complex and delicate dance.
Its acidity and alkali properties cannot be ignored. Under specific conditions, it can exhibit acidic properties and can neutralize with alkali substances, just like yin and yang, transforming conflicts into harmony and generating different products. On the contrary, in other environments, it can be alkaline and react similarly with acidic substances. This conversion of acid and alkali adds a touch of mystery to its chemical properties.
And its redox properties are also unique. It can be used as an oxidizing agent to seize electrons from other substances and cause them to oxidize; it can also be a reducing agent, generously donating its own electrons to initiate a reduction reaction. This plays a key role in many chemical reactions, affecting the direction and process of the reaction, like a core actor on the stage of chemical reactions, every move is related to the overall situation.
What are the storage conditions for this product?
The method of hiding this product is quite important. According to the way of "Tiangong Kaiwu", products of different materials have different methods of hiding.
If the product is made of precious metals such as gold and silver, because of its stable texture, it is not afraid of decay. However, it is very expensive. You should look for a secret and dry place to hide it. It can be placed in a sturdy wooden cabinet with built-in moisture-proof objects, such as lime packs, to prevent moisture erosion and cause dust and spots.
If it is copper, iron and other metal products, it is prone to rust. When hiding, first apply grease to the surface layer, such as suet, lard, etc., to form a protective film to block air and moisture. Then place it in a well-ventilated, dry and moisture-free place. Do not come into contact with damp soil or stone, otherwise it will rust quickly.
As for silk and silk fabrics, their quality is delicate. Hidden in a box, vanilla should be placed in the box, such as Yun grass and patchouli, which can repel insects and prevent beetles. And it needs to be taken out regularly to dry, but it should not be exposed to the hot sun. It should be dried slowly in a cool and ventilated place to prevent the strands from being brittle and the color fading.
Ceramics are a genus that are brittle and fragile. When hiding, wrap them in soft objects, such as old cotton wool and straw, and keep them in a stable place without colliding. Where it is stored, the temperature and humidity should be relatively stable, and sudden changes in cold and hot, dryness and dampness can cause them to break.
Paper products, afraid of moisture and insects. Hide on a wooden frame, a few inches off the ground to prevent the earth from invading. Indoor insect repellent drugs, such as realgar powder, also need to avoid direct light to prevent it from yellowing and becoming brittle.
All these are in accordance with the principles of "Tiangong Kaiwu", and be careful to collect, so as to ensure that the product is not damaged for a long time and preserve its delicacy.
What are the Product Quality Standards?
The Quality Standard of this product is the criterion of its superiority and inferiority, which is extremely important. In the past, the inheritance of skills relied on precise standards to achieve good products.
Its Quality Standard is the first material. The material used must be of fine texture and meet the needs of the made thing. For example, when making a sword, tough and sharp iron should be used. After repeated tempering, impurities must be removed to make the texture pure, so that it can be rigid and flexible, and iron can be cut like mud. If the material is not good, even with superb skills, it is difficult to make a good tool.
Furthermore, the craftsmanship is also the key. From raw materials to finished products, every step is standardized. Such as porcelain, soil selection, mud refining, shaping, firing, all must follow specific laws. When shaping, the lines should be smooth and natural, and the proportions should be coordinated and well-proportioned; when firing, the mastery of the heat is particularly important, whether fierce or slow, all of which are related to the color and texture of the porcelain. A slight mistake may cause the porcelain to be flawed and unusable.
The standard of appearance cannot be ignored. The finished product should be complete in form, without damage or leakage. If there is any decoration, it must be clear and exquisite, which complements the utensils. Like ancient jade, the carved patterns are delicate and vivid, showing the ingenuity of craftsmen, which not only adds beauty but also cultural connotation.
The standard of function is more fundamental. The product must be able to play its due role. Such as farming tools, it should be easy to work and improve efficiency; boats should be able to sail safely on the water, carrying goods and people. If the function is not up to, it will lose its value if it has no watch.
To sum up, the Quality Standard of this product covers materials, craftsmanship, appearance and function. All links complement each other and are indispensable. Only by strictly adhering to this standard can we obtain high-quality products that will be passed down to future generations and used by everyone.
