Glazes are usually derived from wood ashes and rock materials accomplished at high temperatures. On the hypothesis that cullet, which is non-biodegradable and in the Nigerian context unutilized, indiscriminately discarded, hazardous and constitutes serious solid waste disposal challenge, contains poly-chemical oxides of glass former and should fire at low temperature, this study is production of cullet-derived glazes. Samples were collected from dumps, cleaned, heated, pulverized, sieved, washed, dried, elementally analysed and formed into two glaze batches of cullet with ball clay and cullet with potash and ball clay; milled, applied on ceramic tiles; and fired in a kiln at 1100oC.Findings revealed that cullet has the potentials to produce pure compound of silica for glazing. The study has far reaching implications for the environment in solid waste disposal, economic and industrial development, conservation of energy, reduction of deforestation and anthropogenic carbon emission and ultimately contributes towards a cleaner earth.
