Abstract: Red oil drop temmoku is an orange red glaze with white oil droplets. The glaze is prepared using feldspar, quartz, calcite, ferric oxide, bone ash, talc, kaolin, etc as raw materials. Effects of the glaze formula composition, firing schedule and glazing thickness of red oil drop glaze are studied, and the red oil drop glaze with better effect is obtained.The experimental results show that when formulated by weight with 24 ~ 30 % feldspar, 30 ~ 36 % quartz, 10 ~ 14 % Suzhou clay, 10 ~ 12 % calcite, 4 ~ 6 % talc, 4 ~ 8 % bone ash, and 10 ~ 12 % iron oxide, glazed with the thickness of 0.6 ~ 0.6 mm, and fired at 1280 ℃ for 20 min, the red oil drop temmoku glaze has the best chromatic effect.
