Hematite was formed in the mixture heated at 1300℃ for 3 hours containing 5-20wt% of potassium chloride. Hematite was also observed by SEM as hexagonal plate-like crystals on the surface of the samples. However, hematite was not found in the samples cooled down faster than 20℃/min. The slower the cooling rate is, the larger the crystal size is. Close interrelations were found among the degree of red coloration of the sample, the crystal size and the amount of hematite. Hematite in Hidasuki might cause the characteristic red coloring to Hidasuki.}, pages = {61--65}, title = {火襷の呈色におよぼす焼成条件の影響}, volume = {24}, year = {1989}, yomi = {フジワラ, ミネカズ and ヤマグチ, カズヒロ and フクハラ, ミノル and ドイ, アキラ} }
