Follow a pattern below the glaze
Choose a stage to separate body clay, inserted clay, and glaze. This is a qualitative layer model, not a firing recipe or a reconstruction of one Goryeo workshop.
What this model leaves out
Actual clay recipes, drying, shrinkage, firing schedules, glaze chemistry, and historical workshop choices vary. Colors and band thicknesses are explanatory. A flat diagram does not reproduce a curved vessel.
