Ruyao (Ru Kiln 汝窑) is one of the five famous kilns in Song Dynasty. It was named such because the site of the kiln was located in Ruzhou 汝州, Henan in Song Dynasty. Ru kiln is one of the famous porcelain types in traditional Chinese porcelain making, and it was the main representative of the royal porcelain in the Northern Song Dynasty.
This Ruyao set is made of raw kaolin, following the traditional craft recipes and methods, glazed with particular agate. The ruyao painting dipects the Persimmon (柿子, Shì Zi), which in Chinese culture symbolizes everything goes well (事事如意, Shì Shì Rú Yì).
There is one very special attribute of Ruyao, called “Opening Crack”(开片, Kāi Piàn): it means the opening cracks on the glaze (known as crazing). Naturally, with the use of brewing tea, the glaze layer on the surface of the porcelain gradually cracks inward over the years, forming a special and often very beautiful patten.
Therefore, it is fun to nourish the teaware. The glaze cracks will become more like golden silk after long-term moisturizing by good teas. And each Ruyao teaware will look differently.
