The Development of the Cobalt Underglaze Technique

The Yuan Dynasty saw a pivotal development in ceramic technology: the mastering of the cobalt underglaze technique. This technique, which involves painting designs onto the porcelain body with cobalt oxide before applying the glaze, was crucial for the emergence of blue and white porcelain. The development of the cobalt technique was a major technical accomplishment.

The use of cobalt oxide as a coloring agent was not new; however, the Yuan potters perfected the method of applying the pigment and firing it to achieve a deep, vibrant blue color. The Yuan potters learned how to work with cobalt to create stunning and lasting works of art. This technique proved itself very stable in the kiln.

The sourcing of cobalt was also crucial for this development. Much of the cobalt used during the Yuan period came from Persia, highlighting the importance of international trade for ceramic innovation. The reliability of supply played a huge role in the growth of the blue and white industry.

The cobalt underglaze technique allowed for the creation of intricate designs and the precise control of color. This allowed for a much higher degree of design freedom and artistic experimentation. This innovation opened up new possibilities in terms of decoration.

The enduring legacy of the cobalt underglaze technique lies in its impact on later Chinese ceramics and its continued use around the world. It remains a fundamental part of many ceramic traditions around the world to this day. The mastery of this technique is a pivotal event in ceramic history.
