抄録

The bending strength of commercial porcelains for tablewares from ten makers in Tono district, Gifiprefecture was investigated by using test bars of the same size, non-glazed or glazed and fired in respective makers. An unglazed porcelain body which showed the maximum mean bending strength of 8.9kg/mm₂ had a maximum relative density of 97.5% with pore size less than 20μm. The bending strength of unglazed bodies was in the range from 4.9 to 8.9kg/mm₂ and was increased to the range from 7.0 to 12.0kg/mm₂ by glazing. In general, when the compressive stress in glaze was over 2.0kg/mm₂, fracture occurred from the origin in the bodies and the glazing increased the bending strength of porcelain bodies by about 3.5kg/mm₂. Especially, pores at the boundaries between glaze and body generated during firing acted as fracture origins and reduced the bending strength.
