In the field of chemical industry, it is quite famous. In the past, there were skillful craftsmen who were good at making the agent of Dan Hong, and their method was exquisite and extraordinary.
The craftsman was first involved in this industry. He was diligent and eager to learn. He traveled through mountains and rivers to find the genus of all kinds of mineral plants, thinking that it was the source of Dan Hong. Every time he got something, he must examine it carefully, study its nature, and try to change it. Then he returned, set up a kettle in the furnace in the room, calcined it with fire, and quenched it with water. After countless trials, the color of Dan Hong was pure and free.
Its production of Dan Hong, the control of the fire is very important. Fierce fire makes the color dry, and light fire makes the color dark. The craftsman stands by the furnace day and night, observing the size of the fire and adjusting the urgency of the heat, keeping his eyes on the moment, and his mind is focused on nothing else. And when it comes to ingredients, he must also investigate them. The geometry of a certain mine and the number of certain plants are all accurate.
Therefore, the Dan Hong made is bright in color and will not fade away for a long time. It is widely praised in painting workshops and dyeing workshops. Merchants from all over the world, after hearing its name, came one after another to buy Dan Hong products. The name of the craftsman was then passed down near and far, making it a model for the chemical industry. Later scholars all took it as a model and studied the art of chemical industry to carry on the industry of Dan Hong, so that it could continue endlessly and shine in the world.
