The production process of a certain product is actually an exquisite and complicated process. Just like the techniques recorded in "Tiangong Kaiwu", they all have their own unique methods and sequences.
At the beginning, all kinds of materials need to be carefully prepared. The quality of the material is related to the final state of the product, so when choosing, you must be cautious. As "Tiangong Kaiwu" says about making tiles, the selection of clay is very important, and the same is true for the material of this product. It must be pure and appropriate before it can be the starting point for good work.
Then, the material is properly treated. Or grinding to refine, or smelting to purify, depending on its nature. This process requires precise control of the heat and duration, just like the technique of metallurgical casting in "Tiangong Kaiwu". If the heat is not appropriate, the utensils will be difficult to form. The operator must have exquisite skills and rich experience in order to make the material reach the best state.
Furthermore, the step of forming is crucial. According to the shape of the product, it is shaped by mold or hand. The system of the mold needs to be exquisite and accurate, and the manual shaping depends on the ingenuity and skill of the craftsman. Among them, the strength and angle are all exquisite. If there is a slight difference, the shape will be uneven. Just like the pottery in "Tiangong Kaiwu", the craftsman interacts with the clay with his hands to give it a beautiful shape.
Afterwards, the product needs to be specially treated, such as drying, sintering, glazing, etc. When drying, the speed and ambient humidity need to be paid attention to to prevent dry cracking; the temperature of sintering is crucial, too high will destroy, too low will not reach the quality; the method of glazing is related to the appearance and protection, and must be uniform and delicate. All these treatments are to improve the quality and beauty of the product.
Finally, rigorous inspection is indispensable. Check the size, appearance and performance of the product with strict standards. If there are any defects, they must be corrected or discarded. Just like the inspection of finished products in Tiangong Kaiwu, only qualified products can enter the world to ensure reputation and quality.
The production process of this product involves ingenuity in every step, linking the steps and interlocking them to obtain high-quality products, just like the exquisite skills contained in "Tiangong Kaiwu", inheriting and developing the spirit of craftsmen to achieve perfection.
