The Use of Underglaze Copper Red in Qing Porcelain

The use of underglaze copper red was a technically challenging but highly admired decorative technique in Qing Dynasty porcelain, particularly during the Kangxi and Yongzheng periods. Achieving a vibrant, consistent red color was a very complex and difficult process. This required exceptional skill and a very deep understanding of the firing process.

Underglaze copper red, created by applying copper oxide pigment directly onto the porcelain body before glazing, was notoriously difficult to control. The chemical reactions in the kiln would often result in inconsistent colors, ranging from a deep red to a faded or even greyish tone. The results were very difficult to predict or control. The use of copper red required meticulous kiln control.

The successful production of pieces with a clear, bright underglaze copper red was therefore considered a major achievement. Pieces with this color were highly prized and were considered a testament to the skills of the potters. Those pieces that were successfully produced were highly valued. The firing process required a great deal of knowledge and experience.

Underglaze copper red was often used in combination with underglaze cobalt blue, with the red often serving as a highlight for the blue designs. The combination of the two colors is very beautiful and striking. This color combination adds depth and interest to the porcelain design. The complementary colors create an attractive visual impact.

The technical challenges associated with underglaze copper red often resulted in pieces with slight imperfections, which are seen as evidence of the difficult firing process and are now valued by collectors. This demonstrated the degree of skill required to produce this unique color. These slight variations were often accepted as part of the aesthetic.

In conclusion, the use of underglaze copper red in Qing Dynasty porcelain, though technically challenging, resulted in some of the most beautiful and highly prized pieces of the era, showcasing the skill and innovation of Qing potters. The success of this color was an achievement for any workshop. It required meticulous oversight and control.
