Abstract
The correlation between temperature transforming into bloating of a formed sample and nominal temperature equivalent to its refractoriness in the JIS method was positive . This result suggested that refractoriness of Amakusa pottery stone is determined by thermal expansion curves . The various thermal expansion curves were measured under different conditions of milling time of samples , pellet thickress, forming pressure, heating rate and loading. Anomalous expansion due to bloating was observed, and the temperature (T5) giving a linear expansion coefficient of 5•~10-4cm/cm/•Ž was independent of the
