Since no specific product information is mentioned, it is assumed that this product is a "compass". The following reply is in the classical Chinese form of "Tiangong Kaiwu":
Today there is a thing, its function is used to identify the direction, and it is necessary for travel and navigation. This thing is called a compass.
The system of watching the compass has been around for a long time. The wise men of ancient times observed the nature of magnets attracting iron, studied the principle of yin and yang in heaven and earth, and began to make a compass. Its shape is like a needle, and it is ground with magnets, so it has the ability to guide.
Its structure is exquisite, and it is often placed in a plate with a magnetic needle running across a pivot. Divide the direction of the engraving, divided into twenty-four directions, according to the position of the sky trunk, the earth branch and the gossip, and set the direction of the southeast, northwest, four dimensions and eight arteries. The magnetic needle always refers to the north and south. Although it has weathered wind and rain and traveled on the waves, its direction is not easy.
When sailing, the vast sea is connected by water and sky. During the boat journey, if there is no compass to guide, it is easy to lose your way and risk hitting a reef and stranding. Therefore, boat masters use the compass as a treasure. According to it, they set the course and ensure the stability of the boat, reaching a distance of 10,000 miles.
When traveling, the mountains and forests are in the wilderness, and the roads are complicated. The compass also points out the way for the traveler, so that he will not get lost in the remote land of the
The compass is actually the crystallization of my Chinese wisdom, which has benefited future generations and has made great contributions to transportation, geographical exploration and other things. It was passed down in foreign lands and used by various countries, becoming a great help for the exchange and development of world civilizations.

The physical and chemical properties of this utensil are special. Its quality is firm and dense, and it is warm and moist to the touch, like jade but not jade. The sound of knocking is clear and long, and the lingering sound is curling, like the roar of a dragon. Looking at its color, it is colorful and elegant, or like the morning glow reflecting the sky, or like the twilight mist, and it is full of fantasy.
As for its chemical properties, it is extremely stable in ordinary environments, not afraid of wind and rain erosion, and not afraid of the alternation of cold and summer. Although it has gone through the vicissitudes of time, its shape and quality have rarely changed. Even if it is calcined by fire, it is difficult to change its inherent nature. Only the surface is slightly discolored, and when it cools down a little, it returns to the old view.
Its density is moderate, and when placed in the hand, it feels quite solid, but it does not malfunction. Its thermal conductivity is different from that of ordinary things. When held in summer, it is cool and refreshing, but not icy. When held in winter, it is warm and warm, as if there is a slight heat emission.
And this thing also has unique performance in different chemical reagents. In case of strong acid, there are only slight ripples on the surface, which seem to have resistance and have not been easily corroded. In case of strong alkali, it can also maintain its original state without melting. It is a rare wonder in the world. Its physical and chemical properties are beyond the details of words. It needs to be inspected in person before you can appreciate it.

The method of making this product is quite complicated, and it varies from category to category. Here are a few common methods to treat you.
One is the ancient method of processing. First take the high-quality raw materials, wash them with clean water, so that they are clean and free of pollution. Then put them in a special kettle and simmer them slowly. The control of the heat during this period is very important. If the fire is fierce, the raw materials will be easy to burn and lose their original taste; if the fire is small, the effect will be difficult to produce. When boiling, a special person needs to be on duty and stir them in a timely manner to make the heating uniform. When boiling to a moderate level, filter out the dross and take the essence. This is the key to the ancient method of boiling.
The second is the method of grinding and mixing. Choose high-quality materials and weigh them according to a specific ratio. First, grind those with hard texture with stone and grind them finely until they are powdery. The finer the better, so that the effect can be easily exerted. Then add other materials in sequence and stir evenly. In this process, it is necessary to pay attention to the order and strength of mixing to ensure that the materials are uniformly integrated to obtain the best effect.
The third is the method of fermentation. Choose suitable raw materials, after pretreatment, connect to specific strains. Place them in an environment with suitable temperature and humidity to ferment. During fermentation, it is necessary to pay close attention to environmental changes. High temperature will easily cause strain variation, and low temperature will slow down fermentation. After fermentation is completed, follow-up processing, such as drying, purification and other steps, will eventually become a product.
In addition, there are many methods of synthesis, which are difficult to describe because they involve secrets or special techniques. Each method has its own unique characteristics, and it is necessary to choose carefully according to the characteristics, efficacy and needs of the product in order to produce high-quality products.

The common specifications of this product on the market today are as follows.
