The Koryo Dynasty, which lasted from 918 to 1392 AD had a strong Buddhist influence which shaped many of it's cultural achievements.
The finest examples of celadon were produced during the middle and latter part of the 11th century by artisans who remain unknown today.
With the Mongol Invasions which started in 1231 AD the flourishing culture began to decline, and along with it, the quality of the pottery being produced.
In the middle of the 10th century Korean artists, some who had been schooled in China, began creating celadon by using inlay and copper glazing techniques which were developed first in China but only fully developed and perfected by Korean artisans.
The Korean use of these techniques were unique in the history of pottery.
For lack of a proper western term for this unique Korean pottery we have called it by either its true name, Bun-cheong, or "brown porcelain" to help distinguish it from the other colors of pottery.
Baek-ja - Although it is sometimes, incorrectly, called white celadon, Baek-Ja literally means white porcelain and is the name for the white pottery made by Korean artisans. Though the history of Korean pottery stretches back to the Neolithic age and the rough "Black Comb Pottery" produced by early tribes, the pinnacle of Korean pottery was the development and perfection of celadon (Cheong-Ja) during Korea's Koryo Dynasty.
On seeing Korean celadons for the first time, many find little to attract them, or are even somewhat repelled by the subdued bluish or greyish green tones, which they consider monotonous and far removed from the brightly coloured porcelains with which they are more familiar... For guests it is well to have Ming blue-and-white, for it stimulates the appetite.
But if we wish to hold quiet colloquy with them or have them in our room for a long time, such wares are too strong...
The level of fine quality and beauty they were able to achieve in their work surpassed that of other countries and came to be revered by even the Chinese for it's elegant, yet simple beauty.
The Koryo Royal Court also used some of the finest examples of celadon pottery in their palaces both as vessels for daily use and as objects of fine art.
After Korea's liberation from Japanese rule at the end of WWII and through the Korean war (1950-1953) survival, and not art, was the order of the day.
