Cui's Method for Preparing Rouge.
Zicao (Radix Saposhnikoviae, one jin, separately pounded) Baipi (Bark of a specific tree, eight qian, separately pounded and crushed) Hutonglei (Tamarix Gum, half liang) Boshi Baishi Mi (Persian White Rock Honey, one liang).

Take the above four ingredients, place them in a copper or iron pot with eight sheng of water. Boil the water over high heat until it bubbles like fish eyes. Add Zicao. When it boils again, add Baipi and stir to mix evenly. When it boils once more, add Hutonglei and Shimi. After boiling more than ten times, when the residue of Zicao sinks to the bottom, it is ready. Filter through raw silk gauze. Slowly soak stacked silk floss; clean cotton is also acceptable. The size of the resulting cakes depends on preference. After each soaking, clamp the material with bamboo tongs and dry it over charcoal fire like dried meat jerky. Repeat the soaking process. Six or seven repetitions are sufficient. If repeated ten or more times, the color will be richer and more beautiful. (From Volume 9)

Qianjin Yi Fang's Method for Preparing Mercury Frost.
Shuiyin (Mercurius, one jin) Puxiao (Natrii Sulfas, eight liang) Da Cu (Vinegar, half sheng) Huangfan (Calcinatum Aluminis et Ferri, ten liang) Xi (Stannum, twenty liang, refined three times) Xuanjing (Mineral crystal, six liang) Yanhua (Salt flowers, three jin).

First, refine the tin. Heat the mercury until hot, then pour it into the tin. Next, pound Xuanjing and Huangfan until fine, and sift through silk gauze. Pound the tin until crushed. Mix Yanhua, Xuanjing, etc., and moisten with vinegar. Line the bottom of the container with one jin of Yanhua. Spread the medicinal mixture evenly, cover with Puxiao, and seal with a basin. Seal the seams with mud made from salt ash. Dry thoroughly. Use low heat for three days, then high heat for four days, totaling seven days. Stop heating for one day before opening. Collection requires diligence; do not relax even for an instant, or the result will be lost. (From Volume 5)

Cui's Method for Preparing Mercury Frost.
Shuiyin (Mercurius), Shi Liuhuang (Sulfur), Fulonggan (Caulis Longae Cibus, ten liang each, finely ground) Yanhua (Salt powder, one liang).

Separately heat the mercury in a pot. Crush the sulfur into bean-sized pieces and heat it in another pot. After a long time, when the mercury becomes hot and the sulfur melts into liquid, quickly combine them in one pot. Immediate mixing is crucial; otherwise, the two substances will not merge. Once combined, apply heat and stir rapidly without stopping. If you stop, the mercury will separate to one side, and the sulfur will resemble dead ash on the other. Stir until the sulfur turns to ash and the mercury is no longer visible. Mix with Fulonggan until uniform, then add salt powder and stir to integrate. Sieve salt powder into the pot to form a base layer about one fen thick. Then sieve the mixture of sulfur, Fulonggan, and salt powder onto this base, resembling a steamed cake, but do not cover the entire bottom completely. After sieving, cover with another layer of sieved salt powder, also about one fen thick. Cover the pot with a basin and seal the seams with mud made from ash and soil to prevent drying cracks. Ensure no carbon fire heat escapes. Sublimate for one shichen (two hours). Adjust heat from gentle to intense. Upon opening, collect the frost using old chicken feathers from the basin. After one cycle, divide the used earth into four parts. Take one part to mix with the collected frost, grind until smooth, add two liang of salt powder, and sublimate again as before. Discard that portion of earth. Use the remaining earth for further sublimation. In total, four cycles yield the product. Including the initial sublimation and the fifth cycle, discard the earth after each cycle. After five cycles, the earth is exhausted. For more cycles, use fresh earth and repeat the method. Seven cycles make it suitable for use. (From Volume 9)
