Abstract: Taking the wireless enamel(wireless enamel refers to make enamel works without filigree) production technique in jewelry practice course as the research object, combined with years of enamel teaching experience in the Gemmological Institute of China University of Geosciences(Wuhan), this study expounds the theoretical class, design preparation, creative idea and technique practice application from the course teaching objectives and the implementation, which also emphasizes the practical improvability of students' design practice ability and innovative thinking ability. During the period, it focuses on the core processes, such as wireless enamel glaze method, object correction, firing time, composite application and system integration, to help students solve the key and difficult problems in the wireless enamel firing process.
