| Abstract |
| The development of a fast fired body, incorporating 5% wollastonite in place of quartz powder in a stoneware composition, resulted in early maturing by 50°C, decrease in the fired shrinkage by around 26.67%, increase in strength by around 18.69% and bulk density by 3.93% along with reduction in percent thermal expansion by 22.12% (at 600°C) of the test specimen fired at 1200°C in comparison to those of a conventional body. The substantial decrease in the shrinkage and thermal expansion would favourably influence the final product output by reducing losses due to deformation, thermal shock, dunting etc. The reduction in the maturing temperature will be helpful to conserve energy during firing. |
