Book excerpt: "This is the first study that adopts a comprehensive, thorough, and interdisciplinary approach toward early Chinese lost-wax castings. With more than 80 images, this book provides a study on the "norms," which are seldom questioned. By examining the reasons why Chinese founders often chose not to use the lost-wax process they had clearly mastered, the book refutes the idea that lost-wax technology is the only "right way" to cast bronzes. This study demonstrates that a "norm" is in many ways an illusion that twists our comprehension of art, technology, civilization, and history"--
