Ru Kiln

In Chinese ceramic history, there was once a popular saying “Ru Kiln is paramount” In the Song Dynasty, Ru ware, short for Ru official wares, was porcelain made exclusively for royalty.
Ru is porcelain of pristine simplicity, its smooth and clear surface covered with a glaze the color of “blue sky after rain,” and exhibiting subtle crazing. Because of
the exquisite craftsmanship and unique glaze color, the high quality Ru wares were monopolized by the imperial house.

The ware produced at the Ru Kiln is some of the most highly prized of all Chinese stoneware. Until 1986, when the original kiln site was discovered, only 60 intact pieces were known to exist. At the site, archaeologist discovered 22 more intact pieces along with many fragments and broken piece.

The Ru Kiln was established in 1107 AD, during the Northern Song Dynasty (960-1127) to produce items only for imperial use. The kiln was in production during the reigns of Emperors Huizong (1100-1126) and Qinzong (1126-1127), until 1127 when production was halted with the defeat of the Northern Song Dynasty by the Jin Dynasty. Almost immediately the Ru Kiln Ware became incredibly valuable. The kiln was located in Henan Province’s Ruzhou County, which is where the kiln got its name.

The site of the Ru official kiln in the Qingliang Temple is about 20 kilometers west of Baofeng County. The kiln looks little different from ordinary common kilns, but experts have confirmed that these are actually Song Dynasty remains. Within the site, there are 15 kilns, two workshops and 22 garbage pits.

Precious Ru Kiln is the best in the world. Observing the color of glaze you can find it is just like the sun shines again after rain, mile and ancient as well as simple: touching its surface, you can feel smooth and exquisite just like beautiful jade.

The Discovery of Ru Kiln
The porcelain of the Ru kiln is considered to be the most highly prized and rarest of all the ceramics made by the artisans of ancient China. This is because of the limited number of pieces that are in existence today. Before the discovery of the original location of the kiln in 1986, there were less then 60 pieces of Ru china intact.

The kiln site was found in the province of Henan, Baofeng County in the village of Qingliangsi. Through careful archaeological digging there have been 37 more pieces of Ru porcelain uncovered. Of those pieces, 22 were intact and the rest were fragments.

How Ru Kiln China was Made
Ru kiln porcelain has a beautiful smooth vitreous glaze that covers the entire piece including the rims of the mouth and feet. This is because the Ru kiln pieces were supported by thin pieces, called studs that left three or five tiny indentations, about the size of sesame seeds, on the base of the porcelain piece. The studs allowed the glaze to cove the entire vessel.

The glasslike finish of Ru kiln pieces range from a celadon green with a tinge of sapphire blue to sky blue. The pieces generally have fine, irregular crackles all over the surface, called crab claw veins by the Chinese.

Most of the pieces fired in the Ru kiln for the Imperial government were small, measuring only about 8 inches high with the largest measuring 12 inches in height. The mouths of most of the round Ru kiln wares measured from 4-6 inches in diameter. These porcelain pieces include:

Plates
Bowls
Vases
Washer bowls
Brush bowls
