Borax is sweet, salty, cold and toxic. Its chemical properties are unique and have important uses in alchemy, medicine, porcelain making and many other fields.
The chemical name of borax is sodium tetraborate decahydrate, which can hydrolyze in water and is alkaline. This alkaline property plays a key role in many chemical reactions. For example, in ancient alchemy, its alkalinity was used to adjust the pH in the furnace and assist in the refining of medicinal pills. The borate ions produced by its hydrolysis can react with various metal ions to form stable complexes. Like in ancient metal smelting, this property is used to separate and purify metals.
Borax has certain oxidizing properties. Although it is not strong, it can oxidize certain substances under certain conditions. In the field of ancient medicine, it was used for disinfection and antisepsis, which was to use its oxidative properties to kill bacteria. However, due to its toxicity, it is used with extreme caution.
When heated, borax will gradually lose its crystalline water, and its morphology and properties will change accordingly. This property is applied in the production of ceramics. The ancients used it as a flux to reduce the firing temperature of ceramics, making the texture of ceramics more uniform and the surface smoother.
Borax also has good solubility and can dissolve in water to form a uniform solution. This property plays a role in the preparation of pharmaceuticals or the production of special solutions, which is easy for substances to mix and react.
However, it is necessary to keep in mind that borax is toxic. Be careful when using it to prevent poisoning.

The objects of the two ghosts have all kinds of heterogeneity. Their nature is perverse, and they are very different from ordinary things.
The objects of ghosts contain a cold air. Like a ghost lamp, when it burns, the dim light is miserable, and the gloomy atmosphere is reflected everywhere. Its flames are erratic, as if they can be extinguished at any time, and it seems to contain strange power, which can confuse people and make people terrified. Also like a ghost flute, when playing, the sound is mournful, like sobbing, its sound penetrates through the forest and crosses the water, and those who hear it have cold hair and stand upright, as if a ghost is coming with the sound, and it stirs the soul.
Furthermore, ghost devices often have the ability to deform. Or in an instant, it transforms into a ferocious shape, or it suddenly appears, and its whereabouts are mysterious. Like a ghost flag, when the wind blows, strange runes often appear on the surface of the flag, and it can be self-deformed, sometimes stretched like giant wings, sometimes curled up like a strange snake, its changes are gratuitous and elusive.
There are also ghost devices, which can resist evil. However, the power to control evil is not the way of the right path, but to control evil. Like a ghost mirror, it can reflect the shape of ghosts that are invisible to ordinary people, so that evil can not be hidden. However, if used improperly, it will also attract ghosts to get close and suffer their harm.
Ghost devices are also often associated with resentment. Many ghost weapons are transformed by the obsession of those who died with injustice, and they contain sorrow, bitterness and resentment during their lifetime. Holding this object is easy to be disturbed by resentment, and their body and mind are trapped. If you accidentally touch it, or feel cold all over your body, such as falling into an ice cellar, those with deep resentment will even be controlled by it and become puppets of resentment.
In short, the two ghosts are more strange in nature, or contain yin and cold, or can be deformed, or have evil power, and are often resentful. They are very different from ordinary things in the world. You must not play with them at will, and you should stay away to avoid causing trouble.

The main use of 2-% of the building materials is for the purpose of construction.
The main purpose of the building materials is to build houses and city walls.
The main purpose of the building is to form the shape of the house, so as to shelter the rain. And the arrangement of the wall is orderly, so that the wall can be firm, and the moon will not be damaged.
The wall of the city is especially strong. The city of the city must be guarded. With the city of the city, it can resist the invasion of the outside world. Its height and thickness make the invaders overcome. In the past, famous cities and towns have been built with stone walls to protect the territory and the people.
In addition, buildings can also be used on land. Courtyards and streets are made flat, easy to walk and beautiful. There are also buildings and corridors that are built with buildings, which not only facilitate traffic, but also increase the construction of buildings.
And so on, because of its fire resistance, it can be used as a building, to ensure the normal operation of the building, for smelting, manufacturing and other projects.
The main use of 2-% of the buildings is indispensable in the construction of buildings, houses, city walls, or land, building, etc. In the matter of manufacturing, it is the most fundamental material, which is beneficial to human settlements, defense, and engineering.

To make a weapon to ward off evil, there were many methods in ancient times, which are detailed as follows:
First, the method of forging a sword. Using fine iron as the material, choose a good time, and smelt it on the top of the mountain and by the bank of the spiritual spring. In the past, Moxie was cast into a sword. The husband and wife used iron essence from five mountains and gold essence from six he, waiting for the sky and the earth, yin and yang with the same light, and then it became a sword. The sword is sharp and has the power to ward off evil. When casting a sword, there is attention to the heat and hammering. It needs to be tempered thousands of times, so that the impurities of iron are removed, and the essence is condensed. After the sword is completed, it is sacrificed with spiritual objects, such as the blood of auspicious beasts dripping on the sword body, with its auspicious energy to ward off evil Choose peach wood as a board, because it has the air of pure yang, which can drive away evil. Take cinnabar as ink, cinnabar is the thing that reaches the sun and can overcome yin and evil. Use a special pen to write according to ancient runes. The lines of the runes are straight and dense with deep meaning, such as the character "thunder", which symbolizes the power of the god of thunder and can deter ghosts. When writing, the scribe needs to have no distractions in his heart, be in awe of piety, and inject his own yang energy into the runes. After the book is completed, it will hang in the door, which can ensure the peace of the house.
Third, the method of making bronze mirrors. Gu Yun: "The mirror is the essence of golden water, the inner light and the outer darkness." Choose a good bronze, and cast mirrors with exquisite skills. When casting a mirror, engrave a pattern to ward off evil spirits on the back of the mirror, such as the divine beast Taotie, the unicorn, or engraved with gossip runes. After the bronze mirror is made, it is placed under the sunlight and moonlight alternately to absorb the essence of heaven and earth and absorb the spiritual energy of yin and yang. Hanging indoors, ghosts see it, afraid of its light, and dare not approach.
Fourth, the method of weaving a straw rope. Take herbs such as calamus and wormwood, and collect them when the yang is at its peak on the Dragon Boat Festival. The calamus is shaped like a sharp sword, and the aroma of wormwood is strong, all of which have the effect of warding off evil spirits. Weave herbs into ropes and hang them on doors and windows. The incense of vanilla can repel mosquitoes and insects, and can also open up filth and remove evil spirits, so

If you want to do something good, you must first sharpen the tool. There are many people who should pay attention to the way of making the tool.
One is to observe the quality of the tool. As "Tiangong Kaiwu" says, all made tools, the material is the foundation. Good materials can be made of good materials. If the quality is poor, it will be difficult for the tool to be used. Just like smelting iron as a blade, the fine and coarse iron is related to the dullness and brittleness of the blade. Therefore, at the beginning of the utensils, you should carefully examine the material, and do not be greedy for cheap and use poor materials.
The second is the nature of the bright utensils. Each appliance has its own unique temperament, and only when you are familiar with its characteristics can you make good use of it. If you use a saw to cut wood, you should be aware that the sawteeth are dense and narrow, and the suitable wood is also different. If the sawtooth is sparse, it should be coarse wood; if it is dense, it should be made of fine materials. If its nature is unknown, forced use will not only achieve twice the result with half the effort, but also vulnerable utensils.
Third, take care of the protection of utensils. Utensils are like people, and they also need maintenance. Clean them after use and hide them properly, which can prolong their life. Take the axe as an example. Wash them well, apply oil to prevent rust, and place them in a dry place to be sharp for a long time. If they are discarded, rust will breed, and they will eventually become scrap iron.
Fourth, according to the rules of utensils. Each utensils has its own established regulations and usage, and cannot be changed without authorization. For example, the weaving machine has its own rules for pulling and arranging lines. If you change them at will, the fabric will have defects. Follow its rules and follow
Fifth, hold a heart of awe. Although the utensils are lifeless, they gather the efforts of the craftsmen. Have awe of the utensils, and do not wantonly damage or abuse them, so as to live up to the intention of the creator, and also make the utensils perform their functions and pass them on for a long time.
In short, in the use of utensils, when you observe quality, clarity, care, follow rules and have awe, so that you can use the power of the utensils to achieve the success of all things.
