Fluorine-based metaboric acids are all chemical compounds, each of which has its own characteristics.
Fluorine-based ones are very active and have strong oxidizing properties. In the reaction, it often shows the direction of the reaction of the reaction. Taking fluorine (F ²) as an example, this is the existence of fluorine-based compounds, which can react rapidly to many substances. When gold meets, such as iron (Fe), that is, the reaction of the reaction of the reaction of the reaction of the strong, the formation of fluoride (FeF, etc.), this reaction often releases a large amount of oil. In case of (H ²), it can be combined under normal conditions, and even explode to generate fluoride (HF). Fluorinated aqueous solution is a weak acid, but its corrosion property is low, and it can decay glass. The reaction of silicon dioxide (SiO _ 2), which is the main component of the glass, generates silicon tetrafluoride (SiF _ 2) water.
For metaboric acid, the phase is determined. Metaboric acid (HBO _ 2) is white crystal and slightly soluble in water. Its acidity is weak, and it can partially produce hydrogen (H _) in aqueous solution. Metaboric acid is subject to water and is easy to polymerize into polyboric acid. If metaboric acid is added to a certain extent, it can be used to synthesize diboron trioxide (B _ 2O _) water. Metaboric acid also has certain characteristics, and some metaboric acids can exhibit good optical or catalytic properties under specific conditions. For example, some metaboric acid crystals can be used in laser materials because they can generate high-efficiency laser emission under the excitation of specific waves.

Alum stone is unique in nature, has a wide range of uses, and has extraordinary uses in many fields.
In the field of alchemy, its contribution is indispensable. When the ancients were refining alchemy, alum stone was often used as the important thing. Because of its special chemical properties, alum stone can be combined with all kinds of drugs in the cauldron furnace, and can help the formation of alchemy. Or catalyze the reaction, or adjust its quality, so that the alchemy can reach the ideal state, which is important for those who seek longevity and alchemy.
In the dyeing industry, it is also indispensable. In the past, when dyeers dyed, alum stone was used as a mordant. The fabric was immersed in the liquid containing alum stone, and then met with the dye. Alum stone can make the dye more firmly attached to the fabric. The fabric dyed in this way is fresh in color and does not fade for a long time. It adds color to clothing and contributes a lot to the art of weaving and dyeing.
In the road of medicine, it is also used. Doctors know the nature of alum stone, and use it as medicine. Or for external use, use alum stone as a powder to grind and apply to sores, which can dry dampness and relieve itching, detoxify and reduce sores. It can cure skin sores, itchiness and unbearable symptoms, and the power of astringency makes the sores gradually heal. Or for internal use, although the dosage should be taken with caution, it also has a certain curative effect on some phlegm and saliva, diarrhea and other diseases. It can remove phlegm, prevent diarrhea, and adjust the balance of yin and yang in the human body.
In the service of purifying water Putting alum in turbid water can make the suspended impurities in the water condense and settle. The water is cleared as a result, solving the problem of water purification for the ancients and ensuring the safety of water for people's livelihood.
All these, it can be seen that alum stone plays an important role in alchemy, dyeing, medicine, water purification and other fields, and has a profound impact on the lives of the ancients.

The saltpeter and sulphur are the essential materials for making gunpowder, and are also related to the synthesis of realgar and carbonate. There are various methods, and it has a long history. Today, it is described in ancient methods.
To combine saltpeter, sulphur, realgar and carbonate, one method is to first take the pure saltpeter, soak it in water, remove its impurities, then drain it, dry it, grind it into a fine powder, and place it in a clean vessel. Then take the sulfur, melt it, and remove its residue. After condensation, it is also ground into a fine powder, mixed with the saltpeter powder in a certain proportion, and stirred evenly.
As for realgar, you need to choose a pure and high-quality one, and then use a pestle and mortar to finely pound it into a very fine powder. Slowly add it to the saltpeter and sulfur mixture before, and stir it again to make it smooth.
And the carbonated material may be taken from nature, and then calcined and purified to obtain a pure carbonated powder. The carbonated powder is slowly added to the above mixed medicinal materials in an appropriate amount, and stirred very gently to ensure that the ingredients are well mixed.
After mixing, or it can be put into the mortar and lightly pounded with a pestle to make the materials closely combine. There are also those who mix it with water to form a paste, and then dry it and grind it.
If you make this thing, you need to be careful. Saltpeter and sulfur are strong, realgar is also toxic, and carbonated substances also have their characteristics in the reaction. When operating, you must choose an open, ventilated place away from the fire source to prevent accidents. And the proportion of materials, the order of operation, and the mastery of the heat are all key. If the ratio is not correct, the effect will not be achieved; if the order is wrong, it may be dangerous; if the heat is not suitable, it will be difficult to make a good product.
Ancient alchemists and craftsmen have studied many of these synthesis methods and accumulated a lot of experience. Although the years have passed, there are still ancient laws that can be used today. It is necessary to explore them in detail and, under the premise of safety, inherit the essence of the past for today's needs.

The price of saltpeter, realgar, and borax in the market varies from time to time and from quality to quality.
Saltpeter has a strong nature and is very useful in Dan Dao and Medical Dao. In the market, its price may vary according to its purity and origin. If it is obtained from a high-quality place, and it is refined and pure, without impurities mixing, the price will be high; if the place of origin is ordinary and contains some impurities, the price will be slightly inferior. However, the regular price of the market also fluctuates with the year and the change of supply and demand. In a good year, when everything is sufficient, the production of saltpeter is also abundant, and its price may decline steadily; in a bad year, everything is difficult, the output of saltpeter is trapped, and the demand does not decrease, the price will rise.
Realgar is red and has a special nature. It can be used as a medicine to detoxify, and it is also effective in removing insects and exorcising evil. Its market price is also related to quality. The quality is pure and bright, and there are no mixed stones. Everyone competes for it, and the price is not low; if the color is dark and the quality is mixed, the buyer is fresh, and the price is difficult to be high. And the production of realgar, the region is different, the output is different, the origin is close to the city, its transportation cost is low, and the price may be easy; if the origin is remote, the transportation is difficult, and the cost is quite high, the price will increase.
As for borax, it can be used in various processes, and it also has medicinal effects. The change of its price also follows the common sense of the city. New products, with excellent craftsmanship and better utility, have the highest price; while old products, or because of the passage of time, the quality has slightly decreased, and the price may be reduced. And the market needs, if the craftsmanship is prosperous at a certain time, the demand for borax increases sharply, and the supply exceeds the demand, the price will rise; if the demand is few, the supply exceeds the demand, and the price will drop.
In general, the market prices of saltpeter, realgar, and borax are all influenced by factors such as origin, quality, supply and demand, and age. When traders trade, they can obtain their appropriate prices by carefully observing the situation.

"Tiangong Kaiwu" contains that the upstream and downstream industries of ramie have their own divisions, which complement each other and form a complete industrial system.
Ramie cultivation is the source. Farmers choose fertile soil, plow it, and sow ramie seeds in a timely manner. Take good care to prevent drought and flood, and eliminate insect infestations, so that it can thrive. When the ramie grows, cut the hemp stems, which is a primary industry.
After the ramie is harvested, it enters the hemp spinning process. The hemp workers take the hemp stems, peel and soak them, so that the hemp skin fibers are separated. After spinning them by hand or spinning wheel, they form strands into threads. The techniques here are complicated, and the thickness of the threads is uniform, which is related to the quality of hemp spinning and is the key to the midstream industry.
When the hemp thread is ready, it is transferred to weaving. The weaver operates the loom and interweaves the hemp thread into cloth by the method of warp and weft. The density and pattern of the cloth depend on the weaver's skills. After the cloth is made, it is either dyed in various colors or decorated with patterns to enhance its appearance. This weaving and printing is a downstream industry, so that ramie products will eventually become usable cloth.
The downstream of ramie extends to clothing, home textiles and other industries. Tailors follow the characteristics of cloth, tailoring clothes, paying attention to fit and style. Home textile craftsmen make beds, mats, etc., so that ramie is used more widely.
In contrast to yellow cypress, its planting also needs to choose a suitable place and pay attention to maintenance. When the cork grows, peel off the bark, which is the primary production.
The cork of cork is processed, and the key midstream link is to use it for medicine. Pharmacists follow the ancient prescriptions, either burning or boiling, to remove its toxicity and improve its efficacy.
In the downstream industry, doctors use cork as medicine to treat diseases, such as clearing away heat and dampness, purging fire and detoxifying. There are also pharmaceutical workshops that use cork as raw materials to make pills, loose paste pills and other over-the-counter medicines, which are circulated in the city and benefit patients.
The upper, middle and lower industrial chains of ramie and cork, each performing their own duties, are interlinked, promoting industrial development, meeting the needs of people's livelihood, and have important contributions to the national economy and people's livelihood.
