"Tiangong Kaiwu" is a scientific and technological masterpiece written by Song Yingxing in the Ming Dynasty, and many crafts are detailed in the book. However, because no specific products are mentioned, the following takes the common porcelain manufacturing as an example to explain the method of making billets in the ancient classical Chinese way.
The first choice for porcelain billets is soil. It is necessary to choose delicate and pure clay, which is the foundation of porcelain billets. In the mountains and mountains, explore the best soil. Its quality is warm and moist, its color is milky white, and it is pinched into mud without sticking to the hands. After
obtains the soil, it is transported to the workshop, placed in a stone trough, and soaked in water. When the soil is as soft as mud, pounding it repeatedly with a pestle and mortar will make the particles of the soil finely and evenly, remove impurities, and make its texture more delicate. When pounding, you must use appropriate force and rhythm in an orderly manner to ensure that the mud does not have coarse and hard lumps.
Next, place the pounded mud on the pottery wheel. The craftsman sits on the side of the wheel and pulls the wheel with his hands to make it rotate at a uniform speed. Hold the mud with both hands, according to the shape of the heart, slowly pull it, or make a bowl or a bottle. The fingers are agile, and the fingers are precise and precise. The mud will gradually form a blank shape as you move it. At this time, the craftsman's skills are fully displayed, and the priority of the method is related to the success or failure of the green body.
The green body is just formed, and it still Use bamboo knives, wood scrapers and other tools to carefully trim the surface of the green body to make it flat and smooth, with smooth and natural lines. When trimming the green body, do not hurt the green body, nor make it uneven in thickness. After finishing the shaping, place the green body in a ventilated place to dry it naturally in the shade. The drying process takes a long time and should not be exposed to the sun to prevent the green body from drying and deforming.
So far, the process of making the blank of porcelain has been completed. This skill has been passed down for thousands of years, and it takes craftsmen to study it carefully before they can make a beautiful green body and lay a solid foundation for subsequent firing.

When this product is stored and transported, all kinds of precautions need to be paid attention to.
When storing, the temperature and humidity of the environment should be the first priority. If the temperature and humidity are too high, it may cause the product to get damp and deteriorate, which will damage its quality. When placed in a cool, dry and well-ventilated place to ensure its stability. In case of heat, it is necessary to prevent high temperature attack, and a cool storage can be set up to control the temperature in a suitable range. And the storage place must be clean and odor-free, so as not to cause the product to smell and damage its original quality.
Furthermore, the product stacking is also exquisite. Do not stack too high to prevent deformation and damage under heavy pressure. Between the piles, appropriate spacing should be left to facilitate ventilation and heat dissipation, and it is also easy to check and use.
As for transportation, it is very important to check the road conditions. If the road is bumpy, or the product is damaged by collision. Driving should be stable and avoid violent operations such as sudden brakes and sharp turns. And within the means of transportation, the environment should also be paid attention to and should be kept dry. In case of rain, snow and other weather, it should be tightly sealed and covered, and the product should not be stained with water.
At the same time, different products have different characteristics and may require special treatment during transportation. If it is perishable, it should be equipped with refrigeration equipment to ensure its low temperature environment; if it is fragile, the packaging should be tight and reinforced with cushioning materials to reduce the risk of damage.
In addition, the transportation time should also be controlled. It is advisable to reach the destination quickly, reduce the time of the product in transit, and avoid changes due to long-term storage. In this way, careful attention in storage and transportation can ensure the integrity of the product and its full function.
