COMMENTS: Some experts have contended that smothering pottery during the firing process creates a carbon smoke that penetrates the pottery, turning it black. Even though several books describing black pueblo pottery attribute the color change to carbon, the reduction of iron oxide is the correct mechanism. Ceramicists, describing ancient styles of Old World pottery, state that iron impurities in clay form red oxide at red heat, but if air is lacking during firing, iron impurities in clay form black magnetite.
