Manufacture of sodium ferrocyanide
There is an industry now, specializing in the manufacture of sodium ferrocyanide. The industry's initial rise, a wide collection of good materials, selection of iron sources, supplemented by cyanide, to ensure purity and stability.

In the workshop, the craftsman abides by the law. First mix iron and cyanide in a delicate ratio, put them in a kettle, and boil them slowly, during which the temperature changes and the temperature is controlled. If the fire is fierce, the quality is changeable, and if the fire is small, it will be difficult to achieve, so the control of the heat is very important.

And carefully adjust the reaction environment, or pass the air, or close it to choke, so that the reaction is smooth. And in the process, use exquisite instruments to measure its changes in detail, record the millimeter, and do not let it go wrong.

After the reaction is completed, the product is initially formed, and it needs to be filtered and fine-analyzed. Filter its residue, separate its miscellaneous barren, so that sodium ferrocyanide is pure and flawless. Then carefully store it, prevent moisture and moisture, and wait for it to be sent to the four sides for all needs. This industry, with ingenuity and quality, is the manufacturer of sodium ferrocyanide, and does its best to make it a high-quality product, which will be renowned in the world.
