What were the metallurgical technologies in Sui and Tang Dynasties?

The History of Ancient Metal Smelting and Processing Engineering Technology in China comprehensively and systematically introduces the basic course and main technical achievements of the emergence and development of ancient metal smelting and processing technology in China through a large number of literature research, archaeological objects and their scientific analysis, simulation experiments and traditional process inspection. The History of China Ancient Metal Smelting and Processing Engineering Technology is not only a summary of the author's decades of research work, but also a concentrated reflection of the latest research results in the history of metallurgical technology in China. The book is divided into eight chapters according to historical years, from Yangshao-Longshan culture to Ming and Qing Dynasties. Each chapter is divided into sections according to the technical system, and introduces the smelting technology, alloying technology, processing technology, heat treatment and surface treatment technology of ancient metals such as copper and iron respectively. The eighth chapter mainly introduces the traditional metal technology preserved to this day. There is a preface in front of the book, which mainly introduces the basic course of the development of metallurgical technology in the world and the basic characteristics of ancient metallurgical technology in China. Some chapters also discuss the relationship between technology and social and technological ideas. The history of ancient metal smelting and processing engineering technology in China is rich in content, simple in explanation and based on history. Many materials and pictures are published for the first time, and some of them are very precious. The History of China Ancient Metal Smelting Engineering Technology can be read and referenced by historians of science and technology, historians, cultural relics archaeologists, philosophers of science, teachers and students in colleges and universities.
