Ruguan Kiln in the Northern Song Dynasty is a wonderful flower in the history of ceramic development, and it ranks first among the five famous kilns in the Song Dynasty. Experts generally believe that the Ruguan kiln in the Northern Song Dynasty mysteriously disappeared after only 20 years of firing, but only more than 60 pieces survived. Of the 65 known Ru kilns handed down from ancient times, 17 are in the Forbidden City in Beijing, 23 in the Forbidden City in Taipei and 8 in Shanghai. No more than 10 pieces have been lost from Ru Ci to Britain, the United States and Japan.

The scope of protection of Ru Ci's origin is subject to the geographical scope proposed in the Letter of Pingdingshan Municipal People's Government on Determining the Scope of Protection of Ru Ci's Origin (Zheng Ping Han [2005] No.30), which is the administrative area under the jurisdiction of Ruzhou City, Henan Province, and Daying Town, Xiaoqi Town, Shangjiuwu Town, Zhaozhuang Township, Chengguan Town, Yangzhuang Town, stonebridge Town and Zhangba Town of Baofeng County.

Ru Ci is one of the five famous porcelains in the Song Dynasty, which is as famous as Ru Ci, official porcelains, Jun porcelains, Ge porcelains and Ding porcelains. It is named after being produced in Ruzhou, and has the reputation of "Ruyao No.1" in the history of China ceramics. In the late Northern Song Dynasty, Ru Kiln was monopolized by the royal family, which specialized in firing porcelain for the court, namely "Ru Guan Porcelain", or Ru Ci for short. Ru Ci is the floorboard of celadon fired by Ru kiln in Song Dynasty. Ru kiln was built at the end of the Northern Song Dynasty, burned and used as imperial porcelain for the court.

In fact, Ouyang Xiu, a poet in the Song Dynasty, has a very clear direction in his Collection of Returning to the Field: the most beautiful porcelain in Ruyao is glaze, not azure, but pink, that is, emerald green. The true color of Ru Ci porcelain is semi-porcelain, with no obvious vitrification and opaque body.

Gao Lian, a scholar in the Ming Dynasty, wrote in more detail: Ru kiln is actually glazed with agate powder, and the juice is as thick as fat, but the brown eyes in the juice are like crab claws, and its glaze colors are azure, pink green and sky blue. Pink is the best, sky blue is precious.

After the Jin Dynasty destroyed the Northern Song Dynasty, the Ru kiln also perished. It was only twenty years before and after the kiln was opened. Ru Ci was very rare in the Southern Song Dynasty because of its short firing time and few handed down. Ru Ci's skills have a history of more than 800 years. Some people tried to imitate it in Ming and Qing Dynasties, but they all failed.
