What is the Chinese name of this substance?
Because I don't know what the item refers to, the following is an example of "Sinan", modeled on the classical Chinese style of "Tiangong Kaiwu":
Sinan is also an ancient navigational tool. It is shaped like a spoon, with a magnet for it, placed on a smooth copper plate. A guide with the handle of the spoon can be used to identify the direction for those who travel and navigate.
The four corners of the world, the vastness, the distance of business travel, the sea, if there is no Sinan to set the direction, it is like a blind person without a rod, easy to get lost in the way. In the past, when the Duke of Zhou, it may have taken its embryonic form. After years, it gradually became a fixed form in the Warring States Period.
The system of Sinan is very delicate. Those who choose a good magnet, ponder it into a spoon to make its center of gravity stable and flexible. On the copper plate, there are signs such as trunk branches and gossip, which refer to each other with the handle of the spoon. When using it, turn the spoon of Sinan lightly, and when it is still, the handle of the spoon refers to the south.
For Sinan, it can make boats avoid rocks and avoid danger in navigation, and follow the correct channel; for marching, it can make the army know the direction, so as not to be trapped in the mountains, forests and wilderness. Its great contribution is the crystallization of the wisdom of the ancients, and it is the origin of later compasses and other navigation devices. It is a great contribution to the journey of human beings to explore the world.

What are its physical properties?
There are things today. If you want to investigate their wonders, ask them what their physical properties are. This is what everyone thinks, and it is also the key to knowing things.
The person who owns this thing has a firm and soft nature. When its quality is strong, it is as solid as gold and stone, and it can resist the invasion of external forces. Although heavy weapons are added, it is difficult to make it easy to shape; when its quality is soft, it is as tough as a panda reed, and it can change with things. When it encounters twists and turns, it can be bent and stretched according to the situation, without folding.
It also has the nature of cold and heat. When it is hot, it can absorb its energy without dryness, or it is in a state of expansion, the molecules are active, and the movement intensifies; when it is cold, it converts its shape without stiffness, and the structure tends to be tight, as if it is quiet and waiting to change.
And has the nature of light and sound. Light, or reflection, shines on the eyes, like the light of a mirror; or transmission, as clear as glass, so that light passes through. As for sound, knock, its sound may be crisp, like the melodious sound of ringing jade; or dull, like the thickness of a bell and drum, depending on its material and shape.
More conductive and thermally conductive. In electricity, either it is a good conductor, so that the current can flow unimpeded, just like the water of a river rushing in it; or it is insulation, blocking the invasion of electricity, just like the enemy of a strong wall. When conducting heat, if it is a metal, the heat transfer is extremely fast, so that the heat at one end can reach the other end quickly; if it is a wood or a stone, the heat conduction is slow, and the heat transfer can be blocked.
Its density is also important. In the heavy, it sinks in water, like the stability of a mountain; in the light, it floats in liquid, like the lightness of a feather. This is the outline of its physical properties. Although it has not been able to describe its wonders, it can also be glimpsed, so as to help everyone understand the nature of things and use the energy of things.

What are its chemical properties?
The chemical properties of a substance are actually related to its characteristics in various chemical reactions, which need to be explored in detail from various angles.
In terms of its activity, if the substance is at room temperature and pressure, it can easily react with many substances, such as quickly combining with oxygen to produce new substances, or interacting violently with acid to release gas, it can be proved that its chemical properties are quite active. For example, sodium metal is often found in kerosene to prevent it from coming into contact with oxygen and water vapor in the air. Once exposed to air, it instantly darkens, reacts violently when placed in water, swims around and hisses, all of which demonstrate the active chemical properties of sodium.
Stability is also a key factor in measuring chemical properties. If a substance can maintain its own structure and composition under high temperature, high pressure or a specific chemical environment, and does not easily decompose or convert into other substances, it will have good stability. Take rare gases as an example, because their outer electronic configuration reaches a stable structure, it is extremely difficult to react with other substances under normal conditions, and the chemical properties are extremely stable.
Furthermore, oxidation and reduction are also important characteristics of chemical properties. Oxidative substances are easy to acquire electrons in the reaction, so that other substances can oxidize. For example, oxygen, in the combustion reaction, supports combustion and oxidizes combustible substances. Reductive substances, on the other hand, are easy to lose electrons and reduce other substances. Like hydrogen, when reacting with metal oxides, it can capture the oxygen element and reduce the metal.
In addition, the acidity and alkalinity of this substance are also reflected in its chemical properties. Acidic substances can neutralize with bases to form salts and water; alkaline substances are the opposite. For example, hydrochloric acid can react with sodium hydroxide solution to form sodium chloride and water, which is a common manifestation of acidity and alkalinity.
To know the chemical properties of this substance exactly, many experiments are needed to observe its reaction with different reagents under different conditions in order to fully and accurately grasp its chemical properties.

What are the preparation methods?
There are many ways to prepare it, all of which require exquisite methods and ingenuity.
In the "Hardware" chapter of "Tiangong Kaiwu", the preparation of many metals is mentioned. Take the preparation of iron as an example, iron ore is taken and placed in the furnace. In ancient times, earth furnaces were often used, and charcoal was used as fuel, and the blast supported the combustion. The bellows were agitated, and the fire was hot, and the temperature gradually rose. When iron ore is heated, the oxides of iron react chemically with charcoal. The carbon of charcoal reduces the oxides of iron to separate the iron. This process requires precise control of the heat and ventilation. If the heat is insufficient, the iron is difficult to separate; if the heat is too strong, the iron is easily melted.
There is also a unique method for the preparation of copper. The common method is the bile copper method, which uses the chemical reaction between iron and copper sulfate solution. Take the bile alum water containing copper sulfate and put it into the iron block. The activity of iron is higher than that of copper, so the iron replaces the copper from the copper sulfate solution and adheres to the iron block. This is wet copper smelting. The operation is relatively simple, but it is necessary to pay attention to the concentration of the solution and the amount of iron block to obtain high-purity copper.
There is also the preparation of gold and silver. Gold is mostly from placer ore. It is first washed to remove impurities such as sand and stone, and then mercury is amalgamated to form an alloy with mercury. After heating, the mercury evaporates, leaving gold. The production of silver is often extracted from lead ore, and the lead is oxidized and separated from silver by processes such as calcination.
All kinds of preparation methods rely on the skills and practical experience passed down by craftsmen from generation to generation. It is necessary to carefully consider many factors such as materials, heat, operation steps, etc., in order to obtain excellent products.
