This resulted in a perfectly smooth black surface. The successful firing of Eastern Han celadon porcelain is a major achievement in the history of ceramics and an essential leap forward. Celadon mica is the main raw material for making celadon ware. It contains less organic material, is less viscous and less absorptive, and is mixed with hydromica-based minerals. Many areas in Zhejiang province are rich such raw material.
It is not surprising that the first more mature celadon-glazed porcelain first appeared in Shangyu, Zhejiang Province. At the same time as the invention of lime glaze in the Shang dynasty, the method of brushing glaze on pottery had already been mastered. But because the initial glaze making process was not yet mature, and the glaze method was simple, so the glaze layer was very thin and uneven, and could crack easily during the firing process.
By the Han dynasty, the glaze dipping method appeared. This made the body and the glaze bond firmly, and made the glaze thicker and more transparent.
On the basis of the better selection and production of raw materials, the dragon kiln of the Eastern Han Dynasty was also improved, which created external conditions for the firing of porcelain. Let us take a look at this Eastern Han dynasty celadon-glazed porcelain jug. It is The jug is covered with celadon glaze both inside and outside the body, except for the outer bottom. The neck and shoulders are incised with water-wave motifs, and the abdomen is incised with a dense string pattern.
The original celadon glaze turned brownish due to secondary oxidation, yet we can still see that the glaze is even in colour and thickness, without cracks. Although this piece still falls short of mature porcelain, it is a much more advanced version of primitive porcelain, and is one of the earliest porcelain pieces found in China. After the end of the Han, celadon ware produces during the Six Dynasties period kilns were established in Ningbo-Shaoxing region in Zhejiang province.
The ingredients are carefully mixed as not enough or too much of something can dramatically alter the final outcome. Some wares were coated with a thin layer of slip containing iron before they were glazed.
The method of creating Longquan pottery is incredibly precise as with all celadon wares and actually goes through a cycle of six stages of heating and cooling. The temperatures reach a maximum of degrees Celsius and through the entire process, the firing of the stoneware glazes are carefully controlled. Across countries and centuries, celadon has seen a huge range of shapes, sizes, and uses.
Sometimes the works were etched with a delicate style called sanggam. The sanggam technique was very common in Korea and involved etchings being done into dry clay and then filling the pieces with black or white slip, then coated with a transparent glaze.
