The Ru Kiln, located in Lunru County, in the Chinese province of Henan, is another important Celadon school that grew up in northern China during the Song Dynasty.
Ru Kiln porcelain also has slight cracks, which are created by a small percentage of iron in the glaze that oxidize and turn greenish when fired. The cracks will become more and more noticeable as they absorb the tea liquid, the process is quite similar to the Yixing teapot.
