Ru Porcelain Supporting Nail Craftsmanship

The Ru porcelain supporting nail craftsmanship refers to a special technique used in the firing process of ancient Chinese Ru kiln porcelain. This method involves using small nails (pieces of refractory material) to support the porcelain before firing. The purpose is to prevent the porcelain from coming into direct contact with the kiln floor during high-temperature firing, thus avoiding contamination or sticking. Ru porcelain is famous for its sky-blue glaze and delicate texture, and the supporting nail technique is one of the essential methods to ensure the quality of the porcelain during production.

Gongdao Cup 

Meaning Fairness Cup, also known as the equal cup or equal water cup, is a type of tea utensil primarily used in tea ceremonies to ensure that every guest receives tea of the same concentration. It is usually made of porcelain, glass, or other transparent materials and has a small divider or pillar in the center to control the flow of tea when pouring, ensuring that the tea is evenly distributed into each cup. The design of the Fairness Cup reflects the spirit of fairness and sharing, making the tea ceremony more harmonious and orderly.
