Lime glaze is a commonly used glaze in the production process of traditional lime glaze ceramic. Due to the difference in raw materials and calcination process, the appearance and color of lime glaze will be different. In order to verify the surface gloss of lime glaze, a gloss meter can be used to measure. The lime glaze uses calcium oxide as the flux, and the glaze whose molecular number of calcium oxide should account for more than half is the lime glaze.
