"Tiangong Kaiwu" says: "Where nitrate, Huayi is born, China specializes in the northwest. Its quality follows the real estate, and the color ribbon is yellow and white, and there are variegated colors." Saltpeter, that is, potassium nitrate, occupies a key position in traditional gunpowder. Saltpeter with sulfur and charcoal can be used to make black powder, which is one of the four great inventions of our country in ancient times.
The property of saltpeter has the ability to support combustion. In the midst of fire, saltpeter can release oxygen, causing the flammable material to surge in speed and rapid fire. When the ancients were refining alchemy, they occasionally obtained this property, and then used it in military, fireworks and many other fields. In military affairs, it is the key to firearms. Guns roar and rockets fly, all relying on saltpeter to support combustion. In fireworks, saltpeter is also a source of splendor. Colorful fireworks bloom in the air, and saltpeter is indispensable.
In addition, saltpeter also has a place in the field of medicine. Its cold nature has the effect of clearing away heat and purging fire. It can treat swelling and pain in the eyes, sores in the mouth, etc. The ancients used it as medicine. With its cold nature, it can calm the heat in the body and relieve the poison of the viscera.
In addition, saltpeter is also used in industry. In ancient times, although the industry was not as developed as it is today, saltpeter was used in some metal smelting. With its oxidizing properties, it can help separate metals in ores and improve metal purity.
Looking at it, the quality of saltpeter is to support combustion in fire, clear heat in medicine, and help refining in work. Although it is an ordinary thing, it played a crucial role in the life of the ancients, military, industry, etc., it is a wonderful substance in heaven and earth.

Mercury is eighteen taels, which is the amount of mercury. Mercury is also a chemical substance, known as "mercury" in ancient times. Its unique properties and many chemical properties.
Mercury is liquid at room temperature, which is one of its remarkable characteristics. Its fluidity is very good, like the rolling of silver beads, which can move freely in various containers. And the density of mercury is quite high, about thirteen times that of water. When placed on mercury, if the density is less than that of mercury, it can float on it.
The chemical stability of mercury is also considerable. Under normal conditions at room temperature, mercury does not easily react with oxygen in the air, so it can maintain its liquid state for a long time. However, under heating conditions, mercury and oxygen can combine to form mercury oxide. This reaction shows that mercury can chemically change with oxygen under certain conditions.
Furthermore, mercury has a certain metallic activity. Although its activity is inferior to that of common active metals, such as sodium and potassium, it can also replace some metal ions. If mercury is placed in a solution containing silver ions, mercury can replace silver ions and precipitate silver elementals.
Mercury also changes in chemical reactions. Common valence is + 1 and + 2. For example, mercury in mercurous chloride has a + 1 valence, while mercury in mercury chloride has a + 2 valence. This change in valence is related to the gain and loss of electrons in mercury in chemical reactions.
Although mercury is a chemical substance, its toxicity should not be underestimated. Mercury and its compounds can invade the human body through the respiratory tract, skin and digestive tract, causing serious damage to the human nervous system, kidneys, etc. Therefore, when using and handling mercury, extreme care should be taken and strict operating procedures should be followed to prevent the harm of mercury poisoning.

To make one -% poisonous medicine, the method is as follows:
First take the high-quality poisonous feather, wash it with clean water, and remove its dust. Then put the poisonous feather in a tile kettle, add water from a spiritual spring, and the water should not exceed the poisonous feather. Burn with the fire of mulberry wood, the fire should be slowed down, so that the water is slowly boiling. Wait for the water vapor to evaporate in the kettle, the color of the poisonous feather gradually fades, and the medicinal power is precipitated in the water.
At this time, remove the mulberry fire, take a fine silk sieve, filter out the residue of the poisonous feather, and leave its clear liquid. Prepare another jade bowl, pour the clear liquid into the bowl.
Find the red copper tripod again, wash and dry. Pour the obtained clear liquid into the red copper tripod, use peach wood as firewood, light a small fire, and make the clear liquid slowly concentrate. During this period, special personnel need to watch, and do not leave it slightly to prevent it from boiling.
Wait for the clear liquid to gradually form a paste, cease fire. While it is warm, pour the paste into a special porcelain bottle, seal its mouth, and do not make it breathable.
When making this medicine, it is necessary to choose a good time and do it in a quiet place. And the operator should purify the body and fast, without distractions, so as to keep the medicine pure. The utensils used also need to be clean and stain-free, in order to achieve this -% Poison 18 taels of medicine. Only this medicine is highly toxic, and when there is a surefire solution and it must be used, it must not be used lightly to avoid major disasters.

When it is too late to hide, it is necessary to pay attention to all relevant matters in order to ensure the safety and integrity of the environment.
When it is too late to hide, the first priority is the environment. The degree of sensitivity is sensitive, and it should be placed in the degree of determination. Generally speaking, the degree of tolerance is between five and eight degrees Celsius in 20. If the degree of tolerance is high, it is easy to be impatient, eat less, and even get sick; if the degree of tolerance is low, the quality of life should not be ignored. The degree of tolerance should be kept at 60 to 70%. The degree of tolerance is high, easy to breed bacteria and easy to contract diseases; if the degree of tolerance is low, the moisture is easy to lose, which affects its normal growth.
Furthermore, the place where it is hidden is clean and delicious. The taste is sensitive, and the taste is easy to grow. The place should be cleaned regularly to remove the waste, leftovers, etc., to prevent the growth of germs. And in the process of communication, it is still necessary to keep the air fresh. However, it is also necessary to avoid direct blowing.
It is especially important to use suitable containers, such as bamboo baskets, boxes, etc. Containers should be soft, such as dry mulberry, grass, etc., to prevent damage on the way. The density of the container should also be appropriate, and it should not be used. It is easy to cause death or disease.
In the process, it is still necessary to control the degree. Ice packs, protective materials, etc. can be used. If the journey is slow, it needs to be filled with food. It is advisable to use new and polluted mulberry, and the amount of feeding should be moderate, so as to avoid more or less. And the speed should be fast, so as to reduce the impact of external adverse factors. In this way, it is possible to protect the health of Tibet and lay the foundation for the production of food.
