2018年11月7日 19時42分Tobe-yakiUmechans finish making the ash of plums. Theyworked very hard. They completed test pieces with the cooperation of Karasudani-sensei,a teacher of Tobe branch school. Interestingly, themixture of Fukushima feldspar (20%) and the ash (80%) developed the strongestcolor and there was no effective color development with only the ash. Inaddition, when they covered a test piece with transparent glaze, the colordisappeared after it was baked. They try to analyze ingredients and make a mechanismof plum’s coloring clear, comparing with coloring of ginkgo leaves. (T.Y)
