Japanese ceramics generally refer to Chinese black pomelo. The black glaze tea cup represented by Fujian Jianyao was popular in the Song Dynasty of China. According to legend, there were numerous Buddhist temples in Tianmu Mountain, Zhejiang Province at that time. Japanese monks went to study in Tianmu Mountain and often brought back the black pomelo cup used in the construction of the Tianmu Mountain temple when they returned home. This "Tianmu tea cup" became fashionable in Japan, so the Japanese referred to the black sleeve as Tianmu pomelo. temmoku glaze is a sleeve with a large amount of iron as colorant. The glaze is moist and black, and most of the glaze presents stripes and patches. There are obvious vertical flow, thick hanging and kiln change phenomena. The appearance of glaze changes endlessly, including Su Tianmu (i.e. ordinary black glaze), Yao Bian, red oil drop, silver oil drop, gold rabbit hair, silver rabbit hair, gray rabbit hair, wood leaf Tianmu, star lamp, hawksbill, partridge spot, yellow Tianmu, gray quilt and other varieties. Among them, the sky changes with Yao [:! It is the most precious. The iron content of ordinary black glaze and all kinds of tian ü glaze is very high, between 3% and 9%. The oil drop glaze and rabbit hair glaze are both hematite or magnetite crystal precipitated in the black glaze. The crystal size is very small, and they are clustered together in piles. The crystal shape can be seen clearly under the microscope. The crystal color is commonly red and silver, and its color change is related to the nature of the kiln atmosphere at the time of firing Paper Cuttings tianmu, wood leaf tianmu, hawksbill and partridge spot are all composed of bottom sleeve and surface glaze: the composition, colorant, melting temperature and flow ability of the two glaze are different, and after melting at high temperature, they interact to form spots, streaks or patterns of different colors and shapes.
