I. Paleolithic Age:

There are hammered stone tools and ground stone tools.

Jade has existed since the Paleolithic Age, and the earliest is to make and grind stone tools. That is, stone to stone, stone to stone grinding, sharpening stones as weapons or grinding stones into shapes as decorations and so on. At first, it was just a small jade block drilling a hole to make a pendant. Or polished into jade weapons or tools like stone tools.

Second, the Neolithic age:

In the late Neolithic period, jade articles were only carved or polished products, which were large and complicated in shape and could be regarded as handicrafts. In the Neolithic age, grinding stone tools was the main symbol, so was the technology of processing jade stone tools. Stone manufacturing technology has developed from beating to grinding.

Thousands of years later, jade-making technology has gone through the same process. The two may be exactly the same in technology and tools, but jade has other requirements besides practicality, so the technical requirements are more complicated than making stone tools.

Third, the bronze age of Shang Dynasty:

Slavery in Shang Dynasty promoted the development of jade articles. Slavery in Shang Dynasty was extremely developed, and slaves had been put into all fields of social production and life. With the development of agriculture, there is a fine division of labor within the handicraft industry, and the jade-making process is separated from the stone making and becomes an independent handicraft department. At the same time, slaves of Shang Dynasty created splendid bronze culture. The application of bronze tools in jade-making technology has greatly improved jade-making technology, and jade-making tools have gradually replaced stone tools with bronze.
