To make the magic medicine mercury, the method is as follows:
Ancient alchemists, mercury production often begins with Dan sand. For Dan sand, mercury sulfide is also used, and the color is red and the quality is heavy. First choose good quality Dan sand, and crush it like corn, so that the particles are uniform. Placed in a special pottery kettle, this kettle needs to be carefully fired with clay, the wall is thick and dense, and it can withstand high temperature. The kettle is covered with a cover, the lid is tightly closed with the edge of the kettle, and the gap is sealed with salt mud, so that there is no air leakage.
Under the kettle, burn a charcoal fire, and at first slow it down, so that the Dan sand is gradually heated, and its gas is fumigated in the kettle. Then the fire becomes more and more fierce, and the Dan sand is forced by the fire, and the sand is decomposed by heat. When mercury sulfide is heated, sulfur and mercury separate, sulfide into flue gas escapes, and mercury turns into a liquid, flows down the wall of the kettle, and accumulates at the bottom of the kettle.
When the heat is enough, the fire gradually dies down, and the kettle body is cooled. Carefully open the seal, open the kettle and look at it, you can see that there is silver flowing mercury at the bottom of the kettle, which is the mercury made.
There is also a way to make realgar. For realgar, tetrasulfide and tetraarsenic are also used, and the color is orange-yellow and has a peculiar fragrance. Take the raw realgar stone, first clean its impurities, wash it with water, and then dry it. Place it in a stone mortar, and pound it with a pestle mortar to make it powder, the finer the better.
Take an iron tripod and coat the inner wall with turpentine. Turpentine can help realgar adhere and prevent it from reacting chemically with the tripod wall. Pour the good realgar powder into the tripod, cover the tripod with an iron plate, and seal the gap with salt mud. Burn a charcoal fire under the tripod and heat it slowly with a slow fire. When realgar is heated, its internal composition changes slowly. After a long time, you can get refined realgar.
When refining, you need to be careful to keep the heat, and do not use too much or too little. If it is too much, the quality of the medicine will be damaged, and if it is not enough, the effect will be difficult. And the operation place should be well ventilated to prevent poisonous gas from hurting people. The preparation method of these two is a secret that the immortals do not pass on. Now I will describe it here, and I hope that future generations
