Abstract
The mechanical properties of the bone china were evaluated in relation to the method of the glazing to the different body states and the different glaze compositions. The glazing was conducted by glazing to the green body, the biscuit body fired at 800°C, and the sintered body fired at 1240°C. The glaze compositions were raw glaze, fritted lead glaze, and fritted leadless glaze. The mechanical strength of the bone china was enhanced by the glazing to the sintered body with the fritted glaze. The surface roughness and the mechanical properties of the bone china were not dependent on the compositions, in lead glaze or leadless glaze. The mechanical properties were considered to be dependent on the growth of the interface layer by reacting at the glaze-body contact.
