  3. Wash the calcined batch and perform fine grinding by wet milling.
  4. For overglaze colours, melt a glass flux into frit, mix with stain, and grind via wet milling followed by drying and sieving.
  5. For underglaze colours, calcine glass flux at 1150°C-1200°C and process similarly to overglaze colours.
