密陀僧：味辛、咸，性平，有小毒。将其捣碎成细粉，用火煮一个时辰（约12小时），然后用水飞法处理备用。可用于制约野狼毒的毒性。
李时珍说：密陀僧原本是从冶炼银的过程中获取的，现在既然难以得到，就取用煎炼银箔后，银铺炉底的沉淀物来使用。制造黄丹的人则利用其脚底残渣进行炼制。
水银：味辛，性寒，有大毒。如果用葫芦储存它，就不会泄漏；如果不小心撒落在地上，只需撒上川椒末或茶末即可收集起来，或者用真金及钻石吸引它，它就会附着上去。水银畏惧磁石和砒霜。
雷敩说：凡使用水银，不要选用含有草汞的、来自旧朱漆中的、经过其他药物制过的、在尸体中浸泡过的、以及半生半死的（指未完全提炼纯净的）。
取水银的方法：用瓷瓶盛装朱砂，数量不限，用纸封口，放入香汤中煮一个时辰，取出后放入水火鼎内，用炭堵塞瓶口，加热提取出水银。
取草汞（从植物中提取汞）的方法：用细叶马齿苋晒干，十斤马齿苋可得水银八两或十两。先用槐木槌打碎，架在东向向阳处晾晒。
据《广西通志》记载：泗州出产水银，其采集方法极其残忍，有人从外地市场购买，或是逃跑的童仆，或是奸商绑架他人，强迫他们从事这项危险的工作。人们痒得无法忍受，号叫之声彻夜不绝。安南靠近凭祥州的地方，也有水银产出。夷人约定并雇佣工人出卖劳动力，价格不论，数十人被捆绑带走。这是从草中取出的方法，但其过程的惨烈令人不忍听闻，然而考证并不详细，关于名物的记载亦不完整。
轻粉：味辛，性冷，有大毒。畏惧磁石、石黄，忌食一切血类食物。黄连、土茯苓、陈酱、黑铅、铁浆可以解除其毒性。
升炼轻粉的方法：用水银一两，白矾二两，食盐一两，共同研磨至不见星点（即混合均匀无颗粒感），铺在铁器内，用小乌盆覆盖在上面，用盐泥封口……（原文此处中断，通常后续为加热升华过程）。
朱砂（此处文本似乎混淆了朱砂与银朱/红粉的描述，根据上下文“辛，温，有毒”及“升炼银朱法”，此段主要描述的是人工合成的红色汞化合物，如银朱或红粉，但标题为朱砂，且后文提到“真者谓之水华朱”）：味辛，性温，有毒。市面上多以黄丹及矾红掺杂其中，其颜色黄暗，应当辨别。真正的称为水华朱，即光明朱。
升炼银朱的方法：用石亭脂二斤，在新锅中熔化，接着加入水银一斤，炒制成青砂头，继续炒至不见星点，研磨成粉末装入罐中……（原文此处中断）。
丹砂（此处可能指天然朱砂与人造品的对比或混淆，原文逻辑较乱，“今人多以黄丹及”后接“一十四两八分，次朱三”似为配比记录，但语意不全）。
附：制作朱锭的方法：将光明朱细研，用水飞法澄清，去掉水分，使用秦皮、栀子、皂角各一分，巴豆一粒去壳……（原文此处中断）。
使用雌黄制作的假朱砂，雌黄色如……（原文此处中断）。
附：制作印泥颜色的方法：取真麻油半两左右，放入蓖麻子十几粒，捶碎后同煎，使其变成黄黑色，去掉蓖麻籽，用油拌熟艾绒……（原文此处中断），不沾……（原文此处中断），塞住，印文而不生白醭（霉斑）。
Litharge (Mi Tuo Seng): Pungent and salty in flavor, neutral in nature, slightly toxic. Pound into a fine powder, boil over fire for one *fu* period (approx. 12 hours), then use the water-flying method for preparation. It can be used to mitigate the toxicity of *Radix Stellerae Chamaejasme* (Ye Lang Du).
Li Shizhen stated: Litharge was originally obtained from silver smelting. Since it is now difficult to obtain, the residue at the bottom of the furnace in silver shops after refining silver foil is used instead. Those who produce Minium (Huang Dan) refine it from the sediment at the bottom.
Mercury (Shui Yin): Pungent in flavor, cold in nature, highly toxic. If stored in a gourd, it will not leak; if accidentally spilled on the ground, it can be collected by sprinkling powdered *Fructus Zanthoxyli* (Chuan Jiao) or tea powder, or it can be attracted using real gold or diamonds. Mercury fears Magnetitum (Ci Shi) and Arsenic Trioxide (Pi Shuang).
Lei Xiao said: When using mercury, do not use those containing plant-derived mercury, those from old vermilion lacquer, those treated with other medicines, those that have been in corpses, or those that are half-refined and half-unrefined.
Method for extracting mercury: Place Cinnabar (Zhu Sha) in a porcelain bottle in any quantity, seal with paper, and boil in fragrant soup for one *fu* period. Take out and place in a water-fire tripod, seal the mouth with charcoal, and heat to extract mercury.
Method for extracting "grass mercury" (plant-derived mercury): Dry the leaves of *Portulaca oleracea* (Ma Chi Xian). From ten jin of dried leaves, eight or ten taels of mercury can be obtained. First pound with a locust wood hammer, then dry on a rack facing east towards the sun.
According to the *Guangxi Tongzhi*: Si Zhou produces mercury. The extraction method is extremely cruel. People buy them from outside markets, or they are runaway servants, or kidnapped by unscrupulous merchants. The workers suffer unbearable itching and their cries resonate throughout the night. Annan, near Pingxiang Prefecture, also has mercury. Barbarians hire workers to sell themselves regardless of price, binding dozens of people to take them away. This is the method of extracting from grass/plants, but the cruelty is unbearable to hear, and the textual research is incomplete regarding the nomenclature.
Calomel (Qing Fen): Pungent in flavor, cold in nature, highly toxic. It fears Magnetitum (Ci Shi) and Orpiment (Shi Huang). It is contraindicated with all blood products. *Rhizoma Coptidis* (Huang Lian), *Rhizoma Smilacis Glabrae* (Tu Fu Ling), aged soybean paste, Black Lead (Hei Qian), and Iron Slag (Tie Jiang) can detoxify it.
Method for sublimating Calomel: Grind together one tael of Mercury (Shui Yin), two taels of Alum (Bai Fan), and one tael of Salt (Yan Shi) until no star-like particles are visible. Spread in an iron vessel, cover with a small black basin, and seal with salt mud... [Text cuts off].
Vermilion / Cinnabar (Zhu Sha - Note: Text describes synthetic red mercury compounds like Silver Vermilion/Yin Zhu mixed with natural cinnabar descriptions): Pungent in flavor, warm in nature, toxic. It is often adulterated with Minium (Huang Dan) and Alum Red (Fan Hong); its color is dull yellow and dark, which should be distinguished. The genuine product is called Shui Hua Zhu, i.e., Guang Ming Zhu.
Method for refining Silver Vermilion (Yin Zhu): Melt two jin of Resinite (Shi Ting Zhi) in a new pot, then add one jin of Mercury (Shui Yin). Stir-fry until it forms "Green Sand Head" (Qing Sha Tou), continue frying until no star-like particles remain, grind into powder, and put into a jar... [Text cuts off].
Cinnabar (Dan Sha): Nowadays, people often mix it with Minium (Huang Dan)... [Text cuts off, mentions weights and ratios].
Appendix: Method for making Zhu Ingots: Finely grind Guang Ming Zhu, clarify using the water-flying method, remove water, and use Qin Pi, Gardenia (Zhi Zi), and Gleditsia Sinensis (Zao Jiao) each in one part, and one kernel of Castor Bean (Ba Dou) without shell... [Text cuts off].
Fake vermilion made using Realgar (Ci Huang), where Ci Huang's color is like... [Text cuts off].
Appendix: Method for making seal paste ink: Use about half a liang of true sesame oil, add ten or more castor beans, crush and simmer together until yellow-black, remove the castor beans, mix the oil with roasted mugwort...
