Description A wet grinding study of ceramic glazes by varying material to pebble ratio established that the increased material to pebble ratio of 1:4 has not only improved the efficiency of grinding leading to increased reduction in particle size but also resulted in reduction of maturing temperature of commercial opaque and transparent raw glazes and bone china fritted glaze by similar to 150 degrees C due to prolonged grinding to the fineness of similar to 90.0 to 97.0% particles finer than 2 mu m and d(100) value of 3 to 4 pm. However, the glazed surfaces were found not free from defects like crawling, craters etc. A systematic grinding study of the said opaque glaze followed by evaluation of glaze properties such as gloss, smoothness, opacity, maturity etc. has led to the conclusion that the opaque glaze mix containing particles in the range of 72.7 to 85.5% below 10 mu m and d(100) of 25 to 20 mu m not only matured at 1160 degrees C, which is similar to 40 degrees C lower in comparison to the standard glaze maturing at 1200 degrees C but also the fired glazed specimens showed improved gloss (90-91 GU), smoothness, opacity etc. without any surface faults. Further, the glaze maturing range has also been enhanced by similar to 40 degrees C from 1160 degrees to 1200 degrees C
