Support pins are a firing technique unique to Ru ware. Ru ware celadon artisans make tiny, cone-shaped pieces of heat-resistant clay to support the celadon vessels during firing. Once firing is complete, sesame-seed-sized marks remain on the base of the Ru ware celadon, while the glaze surface is preserved as much as possible.

Vessels fired using support pins are glazed all over, with marks left by the pins on the base. These pins are as small as sesame seeds and are placed mainly near the inner wall of the raised foot. They are typically used in groups of three, five, or six, with five being the most common.

One of the greatest challenges of the support-pin technique lies in making the pins. Each one is handmade and must meet strict requirements for shape, size, and angle. Different vessels require pins of different specifications, making the process exceptionally difficult.

In addition, during firing, the vessel is supported by the pins at one or more points rather than resting flat on its base, which creates a risk of tipping over.

Why continue using support pins?

The support-pin technique is a testament to the ingenuity of Ru ware artisans. As inheritors of Ru ware celadon, they have a responsibility to carry this tradition forward. In addition, firing pottery with support pins preserves the glaze surface as much as possible, bringing the minimalist beauty of Ru ware celadon to its fullest expression.

The feet are coated with a smooth glaze that is unlikely to scratch tabletops, offering excellent protection for furniture used in everyday life.
