what does becoming jewelry wholesaler do How to make ancient gold made

wholesale swarovski jewelry china Alchemy is a name that originated in Europe in the 12th century. It was also called alchemy in ancient my country. In fact, alchemy was not refined for gold, but for the sake of life. Although the warlocks did not produce any puzzle crickets, objectively, their behavior played an enlightenment for the development of modern pharmaceuticals and chemistry.
The ancient Westerners believed that metal was a living organic body and could gradually grow into a perfect gold, and this growth process could be artificially intervened. The way they adopt is to isolate the form of gold or soul to turn them into iron and copper such as iron and copper; so that the cheap metal will have the form or characteristics of gold. The soul or form of the metal is regarded as a kind of aura, which is mainly manifested in the color of the metal. Therefore, the surface of the cheap metal is plated with gold and silver as the transformation of gold alchemists.
The general operation process of alchemy at that time was to melt the four types of cheap metals of copper, iron, tin, and lead together, and turn into a colorless dead substance after cooling. This process is called "black change"; Then add mercury to turn the alloy surface whitening. This process is called "white change" or "Chengyin"; the third step is to add a little gold to make the alloy surface yellow. This process is called "yellow change" or "gold"; The last step is to "purify". Through soaking, remove the cheap metal on the surface, so that the alloy presents a pure gold. After the completion of this step, the original cheap metal was derived from the steps, losing its original low -sex soul, and gaining a noble soul, and became gold!
The well -known alchemists in ancient my country, such as Wei Boyang, Jin Dynasty Tao Hongjing, and Sun Si of the Tang Dynasty in the Eastern Han Dynasty. Among these people, Ge Hong, who belongs to the Eastern Jin Dynasty, is the most famous. In his writing "Pu Puzi · Inner Article", it specifically describes the knowledge of chemistry such as refining gold and silver medicine, such as: "Make a big iron 筩 筩 筩 在 在Success, one foot and two inches high, one foot and two inches high. As a small iron, the middle is six inches. , Empty Qing Four or two, a pound of condensate stone, all of the pounds of fine sieves, with the small and small puppets of the puppet, two points thick. One pound of mercury, half a catty of Dan sand, good is not half a catty. In the internal iron kettle, the residence is exposed on the furnace, the lead sales, the inner mercury three or two, the early out -of -the -ware copy was copied by an iron spoon, the name is Liangfei. , Yunmu covers it, Tiegai Town. Take the big stove, sell lead notes in the big cricket, there is no small cricket, go to half an inch, sell the lead for waiting, cook it for three days and three nights. The name is purple flour. Take ten pounds of lead in the iron ware. On the 20th, the inner copper ware must be sold, the inner purple powder seven -square -inch dagger, stirred it, that is, to become a silver. Those who want to make silver. Among the mercury setting iron, the inner purple powder has been on the three inches, and the fire order is obtained. In the water injection, it is silver. "
, although it is not made of gold according to Ge Hong's method, he found that he found that Many material properties and material changes. For example, "Dan sand burned into mercury, and the accumulation of changes is also become a Dan sand", that is, it refers to heating red mercury sulfide (Dan sand), decomposing mercury, and mercury and sulfur sulfur can generate black mercury sulfide, and then become red mercury sulfide. Describe the reversibility of chemical reactions. Another example is "painting iron with Zeng Qing, iron red like copper", describing the reaction of the iron replacement of copper and so on.
