This workshop is specifically for hard enamel and imitation hard enamel pins & emblems. The surplus colors covered on pins and badges must be removed with stoning or grinding, workers have to control the seconds of stoning / grinding, over strength or over seconds will cause metal line too thick; less effort or less second, motifs & texts will not emerge exactly. Grinding must be coordinated with eyes and hands.
