Abstract
The ceramic property of five kinds of Fukui pottery stones occured in Onigatake, Jogatani, Myohoji and Uesaka, was investigated.
The mineralogical composition was identified by means of X-ray diffraction, D. T. A., chemical analysis and electron micrograph methods.
The following properties were measured on 20hrs wet ball-milled samples, i.e. viscosity, plasticity, modulus of rupture, refractoriness and thermal expansion.
Pressed specimens of the wet ball-milled sample were fired in the temperature range of 800 to 1300°C and determinations of firing shrinkage, thermal expansion, water absorption, reflection, modulus of rupture and moisture expansion were made on the fired specimens.
