Originally, the Joseon Dynasty also liked and made a lot of blue-and-white porcelain, which was painted with hoehoecheong on white porcelain.
However, as China’s transition to the Ming and Qing Dynasties became difficult, the supply and demand of Hoihuicheong was cut off.
Joseon tried to develop its own blue pigment called tocheong, but failed, and instead used existing technology to make black and black ceramics.
We began producing our own iron-painted white porcelain, which uses pigments containing a lot of iron to add black patterns that look like they were drawn with ink on white porcelain.
Afterwards, China developed earthenware and secured its own blue pigment, and Joseon also produced blue and white porcelain based on this, or developed its own unique style that combined iron painting and blue painting.
However, due to the nature of the Joseon Dynasty, which avoided the color black, black porcelain technology was at a standstill, and iron coins were said to be favored by the common people because they were cheap due to their black color.
As a side note, the most developed black pottery technology was in Japan, and that’s because they love black pottery.
