This technique traces back to the ancient Chinese. Tenmoku glazes are firing at very high temperatures in a fuel-burning kiln - the fired is controlled to have just enough air to burn the fuel but not more, this produces what is called a "reduction atmosphere". They have a high melt fluidity coupled with an iron content just short of what would normally precipitate and crystallize on cooling. The effect produces a deep rich color at varies with thickness and crystallizes on the edges of contours the glaze thins. These recipes are G2880A and G2894A.
