Ru Yao Celadon Gaiwan and Cups
Ru Yao Kiln celadon wares originate from Henan province. The technique was perfected in the Song Dynasty. The glaze used is unique and contains some small amounts of iron giving the fired glaze a luminescent look to it. Small veins exist after the firing process and with seasoning the veins will grow more prominent and will take on a golden brown color. Ru Yao wares should be cleaned with tea water or spring water and will develop a luster with repeated use. Our Ru Yao "Easy Gaiwan" has twine wrapped handles on each side which keep the fingers cool during your tea brewing sessions.

History of Ru Yao Celadon Ware
Ru Yao (Ru ware) comes from the kilns around Ruzhou in today’s Henan and rose to fame in the Northern Song (11th–12th century). It was one of the “Five Great Kilns” prized at court. Classic pieces were small, simple forms made of fine stoneware and covered in a soft celadon glaze described in old texts as “the sky after rain.” Production was brief and imperial demand was high, which is why original Ru ware is now museum-level rare.
What makes Ru Yao special is the glaze. It’s a potassium–calcium celadon enriched with a little iron and fired in reduction at very high temperature. At peak heat the glaze becomes glass-smooth; as it cools, tiny bubbles and micro-crackle (开片) form, giving the surface its luminous depth and the famously soft, “baby-skin” feel. Modern Ru-style celadon is made in several studios (not just Henan) using the same principles: pale jade to moon-white color, fine crackle that slowly takes on tea color, and an understated form that lets the glaze do the talking.
