Its touch is warm and cool. When you hold it in hot summer, you can feel a trace of coolness entering the skin and removing the heat. When you touch it in cold winter, there is no bone-piercing cold, and it warms your hands pleasantly. Its density is uniform, and its weight is moderate. It is held in the hand without being too light or too heavy. It is just as wonderful as heaven.

In addition, its thermal conductivity is quite good. With its cooking, the heat energy of the fire can be quickly transmitted inside, and the ingredients are easy to ripen and evenly heated, which can ensure the mellow taste of the delicious food. And its heat insulation is also excellent, so it is not afraid of burning hands, and it is very convenient to use.

And its chemical stability is extremely high, it is not afraid of acid and alkali erosion, and it is difficult to change its quality over time. It is like a guardian of the years, witnessing the changes of time and its own eternity. These many physical properties make this product able to show its strength in various uses, which is a rare good thing in the world.

What are the chemical properties of this product?

The chemical properties of this product are as follows:

This product is stable, and it is difficult to react with other things under normal conditions. As the old saying goes: "As stable as a rock, it does not disturb the vulgar things." Just like the ancient wood in the deep mountains, it has withstood wind and rain and does not change its properties. It can withstand the erosion of many chemical reagents. Before strong acids and alkalis, it is like a determined person, standing still. In case of strong acids, it does not show a state of melting, nor does it escape bubbles; in case of strong alkalis, it does not deform and does not change its quality.

However, under certain conditions, this product is lively. When heated to a certain critical temperature, it is like a sleeping beast waking up, and its activity increases sharply. It can react with specific compounds, such as with Class A reagents, when catalyzed at high temperature, the two interact to form new substances. The process is like two sympathizers, transforming into all things. This new organism has unique properties, or has better toughness, or has a different color.

And this product also has a different performance in an oxidizing environment. If exposed to oxygen-rich and well-lit areas, its surface gradually changes slightly, just like the years have left traces on ancient objects. At first, the color changes slightly, and then a thin layer of oxide may be formed. Although this oxide is thin, it protects its interior like a shield, slowing down the further oxidation process. It is quite "self-help, God help".

Furthermore, the solubility of this product also has characteristics. In common organic solvents, some are soluble, and some are rejected. If it is in B solvent, it can slowly dissolve, like snowflakes melting in spring water, evenly dispersed, forming a uniform system; while in C solvent, it is like oil and water, distinct and difficult to blend. This characteristic makes it used in various fields in different ways, each doing its best.

What is the production method of this product?

The production method of a certain product is described in the ancient "Tiangong Kaiwu". The author of "Tiangong Kaiwu" is written by Song Yingxing in the Ming Dynasty, which is a great achievement of all kinds of technological technology and production experience. It is detailed in the method of manufacturing products.

The production of grain is the first priority for seed selection. Those with good seeds have strong seedlings, strong resistance to stress, and abundant yield. The method of seed selection, when looking at its shape and size, choose the one that is full and pure. If you have good seeds, you should plow the soil. The soil needs to be plowed deeply and finely, so that the soil is loose and broken, and the air is passed and the water is seeped, so that the seeds can germinate. When sowing, according to the time and the ground, the density is appropriate. If it is too dense, it will compete for fertilizer, water, and yang, and the seedlings are weak but not solid; if it is too sparse, the ground force is not sufficient and the yield is not high.

As for the silk production of silkworms. Breeding silkworm seeds first, when the spring is warm, the eggs hatch. Feeding silkworms with fresh and tender mulberry leaves, the leaves need to be clean, no exposure, no insects, and no filth. During the growth of silkworms, the silkworm sand is removed, and the silkworm room is clean and well ventilated. The silkworm will be cooked, and a cocoon is placed, and the silkworm spins silk on it to form a cocoon. After taking the cocoon, reeling silk is necessary. Boil the cocoon in boiling water to make the cocoon silk soft, and then draw the cocoon silk, and The first mold is made, using mud or wood as the material, and the shape of the tripod is plastic, so that it is fine. The second model is made, and the range is divided into inner and outer, made of soil or sand, and coated with a parting agent to make the mold and fan can be divided. Melt the metal in a crucible, burn it fiercely with charcoal fire, and when it is metallized into a liquid, pour it into the fan. After cooling, remove the fan and clear the sand, and then polish it, and make it into a tripod.

The method of making porcelain, choose high-quality porcelain clay, wash it, precipitate it, remove impurities, and make the soil delicate. The plastic blank can be hand-molded and molded, and the art can be applied according to the shape. After the blank is formed, it is dried in the shade, and then trimmed to make the surface flat and smooth. When fired in a kiln, control the heat and temperature. At first, it is baked on a small fire, and then it is burned on a large fire. The temperature and firing time are related to the quality of the porcelain. When the heat is sufficient, the porcelain will become a kiln.

This is the method of production described in "Tiangong Kaiwu". Although it has passed through the years, many of these techniques still have reference value.
