Scanning of Potteryware during Drying by a Moisture Analyser

An attempt has been made to show the usefulness of the instrument developed at CGCRI for the purpose of assessing the drying rate of ceramic wares under varied conditions of temperature, relative humidity and electrolyte addition.Two types of bodies, viz. (i) vitreous china and (ii) cordierite, were slip cast and their drying rates were measured under varying conditions. A relation between the dielectric loss, as measured by the instrument, and the corresponding moisture content of the ceramic article could be established. The results suggest that the instrument can be utilized by the whiteware industry in understanding the mechanism of drying to optimise the conditions to be maintained for a particular ceramic ware.
