"Tiangong Kaiwu" said: "The alum is in the shape of five colors, and the sulfur is the general of the group of stones, all of which are changed by fire." Today's words "272-mercury-1-lead-4-arsenite", each of these objects has its own characteristics.
Mercury, commonly known as mercury, is liquid at room temperature, silver-white and metallic, flows like silver, and has a smooth texture. Its density is high, it is volatile, and the vapor is highly toxic. Mercury has good electrical and thermal conductivity. It often exists in minerals such as Dan sand. When heated, it dissolves gas and cools into a liquid. It is useful in alchemy, medicine, and metallurgy.
Lead, blue-gray, soft texture, good ductility, and high density. Its melting point is not high, and it can be easily melted into a liquid when heated. Lead has strong corrosion resistance and can be used as a protective material. In ancient times, it was mostly used for casting money and making tools, and it was also used in medicine. However, its nature is heavy, and excessive use is harmful.
Arsenic stone is highly toxic, white or light red in color, and has a stone-like shape. Its taste is pungent and sour, and it is heated and sublimated. Although arsenic stone is poisonous, it is also used in medicine. It can treat scabies, malignant sores and other diseases. It needs to be carefully processed and strictly controlled when used.
This number has its own characteristics, and is useful and harmful to people. Such as the volatile mercury is toxic, the quality of lead is heavy and difficult to dispose of, arsenic is extremely toxic, when used with caution, according to its nature and good use, can obtain its benefits and avoid its harm, is also the way to use things.

The chemical properties involved in "alum di-mercury-1-water-4-saltpeter" are as follows:
Alum, in ancient times, often refers to a type of metal sulfate containing crystal water, such as chalum (copper sulfate crystal), green alum (ferrous sulfate crystal), etc. Alum substances have many colors, chalum is blue, green alum is light green, they will decompose under heating and other conditions, lose crystal water and may be accompanied by color changes. And alum can be used as catalysts or participate in reactions in some chemical reactions. For example, chalum can be used to prepare Bordeaux liquid and is used in agriculture to control pests and diseases.
Mercury, commonly known as mercury, is a liquid metal that can evaporate at room temperature and is highly toxic. Mercury has a good metallic luster and fluidity, and can dissolve many metals to form amalgams. It is relatively stable in chemical properties, but it can react with sulfur and other substances to form mercury sulfide. This reaction is often used to treat mercury leakage.
Water, a colorless and odorless liquid, is the most common solvent. Many chemical reactions take place in water. Water is composed of hydrogen and oxygen. Under certain conditions, it can decompose and react to generate hydrogen and oxygen. At the same time, water participates in many chemical reactions such as hydrolysis and hydration.
Saltpeter, the main component is potassium nitrate. Saltpeter was often used in alchemy and gunpowder preparation in ancient times. It is easily decomposed by heat, produces oxygen, and has strong flammability. It is one of the important components of gunpowder. It is mixed with sulfur and charcoal in a certain proportion to form black powder. It will burn violently or even explode in case of an open flame.

The land of "272 Canal - Yichuan - Sizhai" has its uses in many fields.
Looking at agricultural affairs, the ditches here are vertically and horizontally, and the water source is abundant, such as the "272 Canal", which draws surging water and moistens the fields of thousands of acres.

If you want to make a "272 Zai Yichuan Four Aperture Mirage" tool, the method is as follows:
First heavy material selection. You need to find a stone with a solid texture and a specific texture. This stone is often produced in the deep ravines of the mountains. Its color is pale gray, it is warm and dense to the touch, and it is clear to knock. When choosing, you should carefully observe its shape, and it is better to have no cracks and no flaws.
Second, prepare all the carving tools. Like a chisel made of fine iron, the edge must be extremely sharp, which can cut stones like mud; and there are small drills, which are used to penetrate the hole, the drill body is tough, and the drill bit is sharp, so that you can apply force accurately.
Then, apply the art according to the plan. First, chisel the stone according to the desired shape, remove the excess, and roughly outline the outline. Its shape should be in line with the principle of the circle of heaven and earth, with edges and corners, and harmonious proportions. Then refine it with fine chisels, so that the surface is smooth like a mirror, and the lines are smooth and natural. As for the method of piercing the aperture, you need to be especially cautious. In a specific orientation, you can slowly enter with a drill, controlling the strength and angle, so that the size of the four apertures is uniform, transparent and unhindered, as if it were made in heaven. The position of the aperture is related to the spirituality of the artifact, and it must be passed down according to the ancient law, and there must be no mistake at all.
