The term “ceramics” means not only traditional earthenware, stoneware and porcelain made of baked natural clay but also “electro-ceramics” formed by sintering fine particles chemically obtainable such as oxide and sulfide. The ceramics is the first tool treated chemi-cally by the human beings about 10, 000 years ago. The ceramics of today, while inheriting its original tradition as a tool or object of art, has been contributing to the human society by giving birth to a multitude of electro-ceramics in response to the requirement of electric and electronic industries. The long history of ceramics reveals various kinds of instructive things in view of both technical and aesthetic points. Referring to the long history of ceramics, the present paper is to describe how various ceramics were invented and improved, and how electro-ceramics came up and progressed in association with civilization and science. The ceramic history also figures one face of Japanese technology, that is, a modification of foreign technology which should be overcome for the further progress of Japanese industry.
