The Reduction Firing Process Behind Neolithic Blackware

Speaker: Dr. Cortney Chaffin Kim

Innovative technology

This video discusses the reduction firing process, one of the most innovative technological achievements in the history of ceramics. In China, the technique was used during the Neolithic period to create thin-walled (eggshell-thin) vessels, including an assortment of elegant drinking cups. The technique transforms red clay into black through a sophisticated kiln process.
