Fireclay was found at Togi Mine, which, is a lignite mine in the southwestern part of Noto Peninsula. The present authors investigated the nature of this clay, such as refractoriness, chemical composition, mineralogical component, d. t. a., electron micrograph, etc. The refractoriness of the clay is about SK 34〜29 (1,750℃〜1,650℃). Chemical composition is SiO_2 43.72, TiO_2 0.49, Al_2O_3 35.68, Fe_2O_3 2.92, MgO 0.47, CaO 0.62, Na_2O 1.05, K_2O 0.40, Ig. loss 13.08, Total 98.43%. Clay minerals are composed dominantly of disordered kaolinite and partly of illite and montmorillonite. The d. t. a. curves show an endothermic peak at near 560℃ and an exothermic peak at 940℃. The properties of Togi Clay are resemble to those of "Kibushi-Clay" but the former has a higher iron content than the latter.
