[source] it is the refined product of light powder.

[preparation method] put the light powder into a flask, seal the mouth of the flask, then bury it in a tile pot filled with fine sand, and heat it slowly for sublimation. After sublimation, take out the flask, destroy its upper part and place it. If it is slightly cold, the sublimate will peel off naturally. Take the sublimate and grind it in a bowl, then put it on the filter paper, wash it with water, alcohol and so on. Finally, add a little temperature and dry it to form a powder.

① Pinhuijingyao: "the method of raising powder and frost is to stir a jin of salt, alum and soap alum into an iron pot and melt them into juice, then stir them with a shovel to form yellow sand, which is called coarse koji. Nashijiu in the iron pestle research order very fine, called the fine curve. Mercury into a Jin, research so that do not see the stars for degrees, is called mercury Qu. Divide it into four parts. First, take the Yangcheng pot, which is five or six inches long, use a jin of fine charcoal ash, add six liang of salt, water and get the place, leave the pot mouth for two minutes, and then dry it in the sun. The nahgqu is divided into two parts, and covered with an iron lamp one or two inches deep. Use iron and zinc at the bottom and iron wire at the top to wrap the lamp tightly with the lamp. Ten liang of salt and 16 liang of white carbon ash are used for external use. Water is mixed with mud to make cakes. They are red and heated until they are cold. Grind them into fine powder and adjust the water properly. Use a small bamboo stick to seal the mouth of the pot. It is about one finger thick. The pots are flat and dry in the sun. Three big iron nails are used to nail them underground. They are three or four inches high and two inches away from the pot. Several bricks are used to encircle the furnace. Four catties of coal and two catties of carbon are used. When the fire is hot, the water can be nine percent full. When the water is less, the water can be added. It often makes the water full, and it still rolls along the edge of the cup. If the fire is big, the pot will be strong. Slowly roll up for small fire, small fire powder does not rise. When the water is above and the fire is below, if you want to help each other, don't light a long line of incense. Take the three incense sticks as the rule. When the two incense sticks are finished, the fire will gradually approach the cup and level with the cup. When the three incense sticks are finished, even if the fire is gone, don't move the pot. When the pot is extremely cold, you can merge the pot. The bottom of the jar is not used. The cream under the cup is scraped off with a knife, and its color is not yet white. When the four parts of mercury starter are all raised, it is grinded into fine powder. When it is put into a jar as before and raised again, its color is gradually white. When it is grinded into fine powder as before and raised again, its frost is as white as cold water stone, so it can be used as medicine. "

② "Ascending refining method: put one or two real mercury powder into the earthen pot to make it even, cover the mouth of the pot with the lamp, coat the seam with salt mud, first spread the bottom of the pot around with small charcoal fire, wipe it with water wet paper without interruption, gradually add the fire until the neck of the pot is covered with fire, and then take it out when it is cold. According to the ancient recipe in waitai miyao, Cui's method of making mercury frost says: use ten taels of mercury and ten taels of stone sulfur yellow to boil them in one pot. For a long time, the heat of silver will dissipate, and then pour them into one pot. If they are less slow, they will not enter each other. They will still stir them in a hurry. For a long time, the sulfur will become ash, and the silver will not be seen. They are twelve taels of lower fulonggan and one tael of salt. Stir them. Don't use the salt to spread the bottom of the pot, but use it as medicine, and use the salt to cover the surface When the pot is covered with salt soil and mud, when the charcoal fire is calcined for one time, it should be gentle first and then martial. When the pot is opened, it should be brushed down. After one turn, it should be divided into four parts: the old soil should be divided into four parts, one part should be mixed with frost, and the salt should be put into two Liang. As before, it should be divided into two liang, and the salt should be divided into one part. "
