Based on the analyses to the ancient literatures, the investigations to the traditional techniques, the examinations and restoration experiments to the unearthed artifacts, this paper introduced the technical characteristics of the lost-wax ("cire perdue") process applied in the bronze founding techniques of ancient China and made systematic commentaries to the proposition of "There was no lost-wax process in pre-Qin Period". In the archaeological discoveries of the past years, many bronze artifacts cast in the Spring-and-Autumn and Warring-States Periods with lost-wax process have been brought to light. Through the scientific examination to these artifacts, we can confirm that lost-wax technique has long history and splendid achievements in China, and the proposition of so-called "There was no lost-wax process in pre-Qin Period" is absolutely groundless.
