Lead and mercury borax are all commonly used in ancient alchemy, and their chemical properties have their own characteristics.
Lead has a soft texture and a silvery white and slightly gray color. In the air at room temperature, a layer of lead oxide or basic lead carbonate is easily formed on the surface of lead, and this layer of film can prevent further oxidation of lead. Lead can slowly react with dilute hydrochloric acid and dilute sulfuric acid to replace hydrogen gas. However, due to the insoluble lead chloride and lead sulfate generated, it will cover the surface of lead and gradually stop the reaction. In case of nitric acid, lead reacts violently with it to form lead nitrate and other substances.
Mercury, commonly known as mercury, is the only metal that exists as a liquid at room temperature and pressure. Mercury is highly volatile and can continue to evaporate into mercury vapor in the air. Mercury has relatively stable chemical properties and does not react with dilute hydrochloric acid or dilute sulfuric acid. However, it can react with oxidizing acids such as concentrated sulfuric acid and nitric acid. Mercury can dissolve many metals to form amalgam, which is often used in ancient alchemy and some metal smelting processes.
Borax is sodium tetraborate containing crystal water. Its aqueous solution is weakly alkaline, and it can dissolve some metal oxides in the molten state, showing different colors. This is often used in ancient alchemy to identify metals or make special-colored glass. Borax loses crystal water when heated, and melts into a transparent glassy substance when further heated. In water, borax will hydrolyze, and its hydrolysis products can form complexes with various metal ions, affecting the properties of the solution.
These three have unique chemical properties and are full of mystery in the eyes of ancient alchemists. They continue to explore their properties and changes. Although they mostly pursue the false purpose of immortality, they have also accumulated chemical knowledge to a certain extent, laying a foundation for the development of chemistry in later generations.

To make mercury dinitrate drug (i.e. mercury fulminate), the method is as follows:
Prepare various substances first, and a certain amount of mercury is required, an appropriate amount of nitric acid is required, and alcohol is also indispensable.
In a clean vessel, put mercury in it, and slowly inject nitric acid. During this period, it must be handled with caution, because the two contact, or produce a violent reaction. When the mercury and nitric acid are fully blended to form a mercury nitrate solution.
Then, add alcohol to this solution at a suitable rate. In addition, when you pay close attention, this step is also prone to change. At this time, the solution starts to have a complex reaction, and gradually white precipitation emerges, which is the embryonic form of mercury dinitrate.
After the precipitation is precipitated, filter it with a filter to separate the precipitation from the remaining liquid. Then, rinse the precipitate several times with clean water to remove impurities. After washing, let the precipitate dry in a cool and ventilated place. Be careful not to approach the fire. Due to the extreme sensitivity of nitrate and mercury, if you are not careful, it is easy to cause a violent explosion in case of fire or impact.
The production of this medicine requires strict compliance with the procedures, step by step with caution, and a slight mistake will lead to disaster. The operator should have skilled skills and a calm heart to achieve this dangerous system.
