There is a substance that is commonly used in chemical reactions today. Looking at the description of "Tiangong Kaiwu", although the words of that time may be different from those of today, we can also observe its approximate use.
In metallurgical techniques, this substance often helps. For example, when iron is smelted, it can combine with impurities in iron ore to separate it, resulting in pure iron. Ancient craftsmen were well versed in this and used it to assist in smelting to obtain refined iron to make utensils, whether it was agricultural tools to help farming, or weapons to defend the country.
In the pottery industry, it is also indispensable. In clay, adding an appropriate amount can change the character of clay. When fired, the pottery can be made denser in texture and better heat-resistant. The pottery, whether for daily eating dishes or for decorative display, is of better quality because of this substance.
Furthermore, in the art of alchemy, this substance is often found. The alchemists want to use chemical reactions to refine the medicine of longevity. Although their pursuit or failure to achieve positive results, the substance participates in many reactions in the process. It plays an important role in the mysterious alchemy furnace.
It is also useful in the art of dyeing. It can be combined with dyes to make the dyes adhere more firmly to the fabric, and the dyed color will not fade for a long time. Whether it is the fine clothes of dignitaries or the commoner clothes of ordinary people, after this treatment, the color can be bright and lasting. It can be seen that this substance has a wide range of uses in many chemical reactions and has a profound impact on the production and life of the ancients.

The common methods of manufacturing high-quality products are manufacturing, manufacturing, machining, welding, powder metallurgy, etc.
The manufacturer is to inject the molten gold liquid into the first-quality molded cavity, and wait for it to cool and solidify. This method is suitable for forming high-quality and large-sized parts, such as bed, cylinder, etc. The method can generate high-quality parts, and use various high-quality materials. The defect is that the parts are prone to pores, trachoma, and other defects, and the mechanical properties are low.
The manufacturer is to apply force to the high-quality gold billet to make it plastic-shaped, and to obtain the desired shape, size, and performance. This can improve the quality of gold and improve its mechanical properties. It is commonly used in the fabrication of parts that bear heavy and heavy loads, such as curved parts, curved parts, etc. However, the blank requirements are high, the production cost is also high, and the molded parts are also high.

Mechanical machiners use cutting, grinding and other means to remove the multi-layer material on the workpiece, so as to achieve the required size, shape and surface roughness. This method has high precision and can process multi-layer materials and low-layer parts, such as high-layer and low-layer parts. However, the processing efficiency is relatively low, and the cost and processing accuracy are relatively low.
Welding, is a method of processing weldments to atoms by adding or adding, or both, using filler materials or not using filler materials. It is often used to fabricate large-scale parts, such as beams, force vessels, etc. Its purpose is that parts of different materials or shapes can be joined into a whole, and the production period is short; the shortage is that the welding joint is easy to generate force and shape, and the amount of product is affected.
Powder metallurgy is a mixture of gold powder or gold powder and non-gold powder, forming, forming and other processes to form materials or products with desired properties. This method is used for making molten gold materials, porous materials and materials with special properties, such as oil-bearing, gold stone tools, etc. It can save materials and reduce costs, but the cost is large and the size of the product is limited.

This product has the quality of combining rigidity and softness. Its quality is strong and tough, just like stainless steel forging, which can resist the heavy impact of external forces without damage. When hit by hard objects, only shallow marks are left, which will not break and collapse. It is strong like a mountain, stable and unshakable.
And its material is dense, the texture is orderly, and the molecules are closely combined, which is the sign of its rigidity. Like city wall masonry, layers are interlocked to build a solid line of defense, and it is difficult for external forces to break its defense.
However, it also has flexibility. It can change with the shape, and it can meander with the trend when it encounters twists and turns, without bending or folding. It can be curved with human force without breaking, just like a branch of a weeping willow, although soft but tough.
Its density is moderate, not too heavy to cause movement stagnation, nor too light and unstable. Holding it in the hand, the texture is solid, but there is no excessive burden, it is easy to hold and flexible to operate.
Furthermore, its thermal conductivity is unique. When heated, the heat conduction is uniform and stable, the temperature is smooth, and there is no sudden heat and cold. Cooking with this food can make the food familiar inside and outside, and the taste is mellow, such as cooking tea in Guding, with a long flavor.
It also has good insulation, which can block the passage of current and place it in electricity, such as a barrier to protect personal safety, like an invisible shield, protecting people.

This product is used in the market, mostly for the help of business, the convenience of daily life and the pleasure of skills.
Looking at the matter of farming mulberry, this product can be used as a farming tool to help farmers turn the soil and reclaim the fields, sow grain, irrigate and fertilize, make the harvest more smooth, make the fields more fertile, and enrich the warehouses to feed the people. In market trade, it can be used as a carrier for merchants, or as a weighing tool, so that the trade of goods is fair and orderly, the circulation of goods and goods, and the prosperity of the market.
As for home life, it can be used for daily use, such as cooking utensils to cook delicacies, and food utensils to hold delicacies, making eating delicate and enjoyable; it can also be used as sleeping utensils and seating utensils, making living comfortable and resting appropriate.
In the craftsmanship, it can be used as a tool for craftsmen. Woodworkers use wood as tools to create exquisite furniture and utensils; potters use it to shape pottery and burn exquisite pottery; weavers use it to weave cloth and make gorgeous clothes. Help all kinds of skills to improve, create a dazzling array of utensils, and add beauty to the world.
The use of this product in the world is related to many aspects of people's livelihood. It is indispensable from clothing, food, housing, transportation to the production of all industries. It brings many conveniences and possibilities to people's lives and work. It is actually a great use in the world.
