Because no specific products are mentioned, the format of "Tiangong Kaiwu" is used to simulate a "glazed" product as an example to answer:
The glazed one is also a precious utensil of ancient times. Its quality is radiant and radiant, like ice and jade, which is really a masterpiece.
The production of glazed glass has a long history. In the past, craftsmen mined all kinds of ores, such as quartz and feldspar, with lead Dan, saltpeter and other materials. First put the materials in a crucible and calcine them with a hot fire. The flame in the furnace is boiling, and the temperature is extremely high. The craftsman must carefully control the heat and must not make a slight mistake. Wait for the materials to melt into one, turn into a crystal clear liquid, and then use special tools to pick an appropriate amount of glazed liquid. At this moment, the glazed liquid is very hot and dazzling. The craftsman relies on his exquisite skills, either blowing or shaping, to gradually form it into the desired shape. There are those who make cups, exquisite and elegant, and can hold fine wine; there are those who make ornaments, with thousands of shapes, lifelike, placed on the desk, adding elegance.
The color of the glazed glass is colorful. There are blue like the blue sky, deep and quiet; like the bright red of the sunset, gorgeous and dazzling; and like the emerald green of emerald bamboo, fresh and natural. The reason for its color is that different metal oxides are added when ingredients are made. For example, copper makes it green, cobalt makes it blue, and iron makes it red. All kinds of changes are wonderful.
In ancient times, glazed glass was mostly hidden by officials and dignitaries, and was regarded as a treasure. One is that its production process is complicated and expensive; the other is that its quality is exquisite, and it is comparable to extraordinary things. In the court, glazed utensils are often used as rewards to show the grandeur of the emperor; in the rich family, they also decorate the facade and show their status. Although it has gone through the vicissitudes of time, the beauty of glazed glass is still admired by the world, and it is endlessly passed down. It is actually the bright pearl of Chinese craftsmanship.

This product has a wide range of uses and can be used in many fields. In agriculture, it can help farming, make the land more fertile, make crops grow more vigorously, and then improve harvests. For example, Leixiao is an important agricultural tool in ancient times. Farmers use Leixiao to turn the soil and clear the land, which greatly facilitates agricultural work and is of great significance in the process of agricultural development.
In the field of architectural construction, this product is also indispensable. It can provide a solid support for the building and enhance the solidity of the building. Just like building palaces and pavilions in ancient times, it is necessary to use solid materials as the foundation and structure to make the building survive the years. Many famous ancient buildings, such as the Forbidden City, rely on fine materials and ingenious structures, and this product may play a key role in them.
In the field of military warfare, its use should not be underestimated. It can make weapons and armor to enhance the combat effectiveness of the army. In ancient wars, sharp weapons and strong armor are the key to defeating the enemy. Weapons such as swords and halberds are forged with high-quality materials to exert great power on the battlefield, protect soldiers and help win wars.
In daily life, this product can also bring a lot of convenience. It can create various living utensils for people to improve the quality of life. For example, making tables, chairs and beds allows people to rest comfortably; making pots and pans for easy cooking and eating. The ancients were meticulous in their daily lives, and the demand for various appliances promoted the application of this product in the field of life.

The physical and chemical properties of this product are special. Its quality is strong and tough, like the genus of gold and iron, but it is especially light. Looking at its color, it is radiant and lustrous, like beautiful jade, but it has a unique light, whether bright or dark, and there is a hidden state of change.
Its touch is also different from ordinary things, cold but not ice, if there is a slight temperature coming from the fingertips, when rubbing, it slips without leaving your hands, and then you feel that the surface seems to have a very fine texture, looming, and there seems to be a deep meaning hidden in it.
As for its chemical properties, it is also quite amazing. Placed in all kinds of common agents, there is no significant change, as if it can separate its own realm and not invade foreign objects. Although the fire is added to the body, it is only slightly hot on the surface, and there is no risk of melting. And if exposed to sunlight, its surface seems to be able to absorb light, and then slowly release it. The color and strength of the light can change with the environment and time, which is really amazing.
It is also observed that it touches the water, and the water does not stick to the body. If there is an invisible film in between, the water droplets roll on it, like balls on a jade plate, exquisite and clear, which is amazing. Although it has undergone various physical and chemical changes, the essence of this product has not been damaged at all. It can be said to be a rare wonder in the world. Its physical and chemical properties far exceed those of ordinary people. It is actually the wonder of creation, and extraordinary things can be compared.

When making this object, all matters need to be treated with caution. The selection of the first material, the quality of the material, is related to the quality of the object. Fine materials should be selected, and those with tough texture and pure color are preferred. If the material is defective, the finished product is difficult to achieve.
The second is the craftsmanship. When applying the knife, you should follow the ancient method, without distractions, and your hands should be steady and accurate. If you are carving, the lines must be smooth and natural, with ups and downs, and not rough. If the carving is messy and the shape is inaccurate, it will damage its charm.
Grasping the heat is also critical. When calcining, the size and duration of the fire are fixed. If the fire is large, the object is easy to burn, and if the fire is small, the quality is not ripe. It is necessary to observe carefully, adjust in a timely manner, and ensure that it is just right to achieve the ideal texture and shape.
Furthermore, cooperation and cooperation should not be underestimated. When everyone works together, they should perform their duties and take care of each other. Only when the division of labor is clear can there be an orderly manner; smooth communication can avoid mistakes. If each other shirks the blame and cooperates out of order, everything will be difficult to achieve.
The production environment also has an impact. The place should be clean and quiet, free from interference. The accumulation of debris and noise can easily distract people and cause operational errors. Therefore, creating a good environment is beneficial for production.
In addition, the inspection process is indispensable. Every step should be carefully inspected, and if there are any gaps, it should be remedied in time. When the overall completion is completed, it is necessary to comprehensively review to ensure that there is no danger. If the inspection is neglected, the defects will remain, and it will not be perfect in the end.

The storage conditions of this product are crucial to the maintenance of its quality and utility. Although "Tiangong Kaiwu" does not describe the storage conditions of specific products in detail, the process principles and practical wisdom contained in it can be used for reference.
When storing a product, the temperature and humidity of the environment are the first. If the humidity is too high, it is easy to breed mold and cause product spoilage; improper temperature, or change the properties of the product. Taking grain storage as an example, it needs to be placed in a dry, ventilated and moderate temperature place. Although the specific value of grain storage temperature and humidity is not explicitly stated in the book, according to its cognition of grain characteristics and production practice, it can be known that dry ventilation can avoid moisture and mildew of grains and maintain their good quality.
Furthermore, light is also a key factor. Some products have been exposed to light for too long, which may cause decomposition of ingredients and changes in color. For example, certain pigments, fabrics, etc., should be hidden in a dark place and protected from direct sunlight. Although "Tiangong Kaiwu" does not discuss the impact of light on various products in detail, based on daily experience and understanding of material characteristics, it can be inferred that avoiding light is beneficial for product preservation.
In addition, the cleanliness of the storage place and the prevention of insects and rodents should not be underestimated. Unclean places are easy to contaminate products, and insects and rats will damage the products. Therefore, the storage place should be kept clean and protected from insects and rats. "Tiangong Kaiwu" may be involved in the prevention of insects and insects. Although it is not specifically described for product storage and insect prevention, the methods of insect prevention recorded can be flexibly used here.
The storage conditions of the product cover temperature and humidity, light, cleanliness and insect control. According to the process wisdom and practical experience transmitted in "Tiangong Kaiwu", combined with the characteristics of the product itself, suitable storage conditions can be reasonably inferred and established to ensure long-term product quality.
