Ding potters pioneered the technique of fushao (firing a vessel upside down on its rim). Kiln managers saved on fuel by firing a greater number of pots at one time, stacking them in stepped saggars. The disadvantage was the unglazed mouth rim, cleaned free of glaze to avoid the vessel sticking to the saggar. Craftsmen used sheet copper and occasionally gold or silver, cut to size and heated to fit the rims to hide this flaw. Historical accounts suggest that dressing the rim with metal actually enhanced the status of the clay vessel.
