Borax is a common mineral medicine. Its chemical properties are unique and have many wonders.
The main component of borax is sodium tetraborate. In the field of chemistry, it shows the characteristics of salt. Borax is soluble in water, and when dissolved, it can undergo hydrolysis. In aqueous solution, borax partially separates borate ions and sodium ions. This borate ion can be combined with hydrogen ions in water, which makes the solution appear alkaline.
Furthermore, borax has good buffering properties. If a small amount of acid or alkali is added to the solution, borax can move by its own hydrolysis equilibrium, so that the pH of the solution remains relatively stable. This property is quite useful in many chemical experiments and industrial production.
Borax can also react with many metal ions. For example, when it encounters copper ions, it can form specific complexes and exhibit unique color changes. This property is often used in the inspection of metal ions.
Under heating conditions, borax will undergo a series of chemical changes. When heated, borax will gradually lose its crystalline water, and then further decompose to form boron oxide and other products. During this process, the physical and chemical forms of borax will change significantly.
Borax is widely used in many fields such as chemical industry, medicine, and metallurgy. Due to its unique chemical properties, it has become an indispensable and important raw material, playing a key role in many processes and research.

"Tiangong Kaiwu" is a science and technology book written by Song Yingxing in the Ming Dynasty, but the book does not mention the relevant content of "Fang Guang Armor". The following is a virtual answer to this question in the style of ancient classical Chinese, based on the cognition of the physical properties of common ancient armors:
Fang Guang Armor, its physical properties are unique. The quality of the armor is related to the ability to protect. This armor is made of fine iron, etc., which is strong and strong. When forging, the craftsman used clever skills to hammer it, so that the texture was tight and the grains were fine, resulting in a tough quality. Its firmness can withstand the attack of the arrow stone blade. When the enemy blade is added to the body, the armor piece will not be folded or bent, and it can be unloaded from the invisible, ensuring the integrity of the soldiers' bodies.
And the surface of the armor has been sharpened and polished, showing the trend of square light. Light, one can reflect light, wartime sunlight, dazzle the enemy, confuse their mind and attack; second, smooth surface, can make the weapon blade slide, difficult to leave deep marks, reduce the force of killing the enemy's blade cutting. Fang, the shape of the armor is regular, arranged in an orderly manner, and fit each other, like a fish scale and a wild goose. This arrangement not only enhances the overall firmness, but also maintains the flexibility of the armor. When the soldiers are on it, they bend and stretch to the side, so as not to be too stagnant.
Furthermore, the weight of the armor is also one of its physical characteristics. Although heavy, the design is exquisite and evenly distributed. It is slightly thicker and heavier on the shoulders, chest and other harmful areas to increase protection; in the joints and other flexible areas, it is thin and light, so that the soldiers can move freely. And the armor is often lined with soft leather cloth, which increases the comfort of wearing, and the second is to cushion the impact of external forces and protect the skin. Its breathability is also taken into account. There are slight gaps between the nail pieces, and sweat can come out, so that the soldiers can not walk for a long time and are sultry and intolerable, ensuring their combat power.

As described in "Tiangong Kaiwu", there are many ways to make square brass, the details of which are as follows:
First, it is based on copper and zinc and is prepared according to a specific ratio. Ancient craftsmen, who have studied the art of smelting deeply, know the properties of copper and zinc. First take pure copper, melt it, and make it look like gold liquid, tumbling and surging. Then according to the formula, slowly put in zinc blocks, zinc meets copper liquid, and sparks splash in an instant, just like a meteor streaking through the night. At this time, the craftsman needs to use special utensils to quickly stir, so that the copper and zinc are evenly fused, just like water and milk, in order to obtain the first blank of square brass.
Second, the control of the heat is very important. If the fire is fierce, copper and zinc will easily dissipate, causing the alloy ratio to be out of balance; if the fire is weak, the fusion will be uneven, and the texture of brass will not be good. Looking at the fire in the furnace, you need to be as keen as looking at the sky. The flame in the furnace is sometimes as hot as the sun, sometimes as gentle as the candle fire, all by the heart and eyes of the craftsman. When the flame is blue and stable, it is the right moment for the heat. At this time, the brass is in the best state, with a tough texture and a bright color.
Third, the refining process is indispensable. The first brass still contains some impurities and needs to be refined again. Put the first blank back into the furnace and simmer slowly on low heat, so that the impurities slowly surface. The craftsman skims the foam with a long spoon, just like skimming the dust of the world. Repeating this several times, the brass becomes more pure and of high quality.
Fourth, forging and forming. After refining the brass, take it out while it is hot and place it on the anvil. The craftsman wields a sledgehammer, and again and again, the sound of the hammer is crisp and echoes in the workshop. Every hammer gives the brass a new shape and power. Under the hammer, the brass is gradually formed, either as a delicate utensil or a gorgeous jewelry, showing the wisdom and skills of the craftsman.

In the realm of sacrifice, it is used to honor the gods, and requires fire to burn incense candles and sacrifices. The fire taken by the yang flintlock is regarded as the fire of the sky, which is sacred, making the sacrificial ceremony more solemn and solemn, expressing reverence for the gods.
In the military, fire attack is an important tactic. The yang flintlock can make fire at any time. When the battlefield breaks out, light a beacon fire to spread military information, or set fire to the enemy camp or food and grass to disrupt the enemy's position and seize the opportunity.
In daily life, it is necessary to make a fire for cooking, heating and lighting. Yang flintlock can use sunlight to make a fire when there is no conventional fire to relieve the urgent need. Especially in the wild or in emergencies, its role is more prominent, ensuring people's basic survival needs.
In the path of medical treatment, moxibustion is a traditional Chinese medicine therapy, using moxa velvet as raw material to ignite and apply to acupoints. The fire taken by Yang flintlock is pure and mild, and it can be used to ignite moxa velvet, or it can better play the effect of moxibustion to warm meridians and collaterals, harmonize qi and blood, heal diseases, and protect health.
In the production of craftsmanship, copper casting, firing ceramics, etc., fire control is crucial. The fire of the sun flintlock is stable and controllable, helping craftsmen accurately grasp the temperature, improving the quality of utensils, and contributing to the inheritance and development of craftsmanship.
Although the sun flintlock is small, it has functions that cannot be underestimated in many fields such as sacrifice, military, life, medical treatment, craftsmanship, etc. It is the crystallization of the wisdom of the ancients, and has far-reaching influence on the process of Chinese civilization.

The price of the Guanfu market is related to the change of supply and demand, and also depends on the change of times. When it comes to the market price of sunshine methyl ether today, many factors cannot be ignored.
In the past, sunshine methyl ether first entered the market, and those who knew it were rare, and those who used it were few, and its price was relatively flat. Because at that time, demand was not booming, and although there were production methods, the scale was not available, and the cost remained high, the price was difficult to rise significantly.
And later, the development of the world has gradually become more and more in demand for clean energy. Sunshine methyl ether has gradually entered the eyes of everyone with its clean and efficient quality. Those who use it are many, and those who ask for it are many, and its price has also risen. At this time, all kinds of production houses, seeing that they are profitable, have thrown themselves into it one after another, wanting to get a piece of the pie. The scale of production is getting larger, but the demand is growing faster, and the price is still rising.
However, the market changes, unpredictable as the wind and clouds. From time to time, new technologies are developed, which may replace some of the functions of Sunshine Methyl Ether, or improve the production method, and the cost is greatly reduced. In this way, the city of Sunshine Methyl Ether is also affected. The price may fluctuate, or drop or stabilize, and it is difficult to judge.
There are also decrees and regulations, which are related to the rise and fall of the industry. If the imperial court issues an order to promote Sunshine Methyl Ether, setting up many excellent policies for it, or subsidizing it, or reducing taxes, the production can be prosperous, and the price may be stable and decline; if the government orders the opposite, restricting it, the market may wither, and the price may rise accordingly.
In the surrounding cities of Guanfu, if the price of energy sources rises and falls sharply, it will also affect the city of Sunshine Methyl Ether. If oil prices soar, Sunshine Methyl Ether can replace part of the fuel oil, and the demand may increase, and the price will also rise; if oil prices plummet, its advantage will not be obvious, and the demand may decrease, and the price will also be suppressed.
To sum up, the market price of sunlight methyl ether may rise or fall or remain stable for a while due to the interplay of various factors such as supply and demand, technological changes, government decrees, and surrounding market conditions. To know its exact price, you can only obtain it when you consider the situation and carefully observe the changes in various factors.
