Abstract

Wood ash has a long antecedent in the history of ceramic glaze making. Various efforts have been made by potters and researchers to obtain ash from other sources apart from wood which include rice husks, bamboo, bones, etc. This study took a step further to obtain ash from palm kernel shells (PKS) to develop ceramic glazes. PKS were sourced, washed, dried and burnt. Chemical analysis test (XRF) conducted on the palm kernel shells ash (PKSA) obtained revealed the presence of silica (23.97%), iron (33.61%), calcium (1.16%), etc. which showed that PKSA could combine with other materials to produce good glazes. Batches of recipes were weighed, mixed, milled, applied on bisque wares and fired in the kiln. Some good glazes were achieved at 1140°C.
