In view of the need to explore the abundant natural resources available for industrial utilization the analysis and characterization of Kerang volcanic clay deposit was carried out with a view to finding its possible industrial application and establishing a bank of its properties. The chemical analysis was carried out using x-ray fluorescence spectrometer while physical properties such as firing shrinkage was determined using sand sedimentation technique, apparent porosity using boiling point technique, cold crushing strength by compressive load technique, bulk density by gravimetric method, thermal shock resistance using single chamber thermal shock equipment and refractoriness by the cone comparison technique. Chemical analysis showed that the clay is composed of Silica (SiO2) 29.50%, Alumina (Al2O3) 15.58%, Potassium oxide (K2O) 1.28%, Calcium oxide (CaO) 2.43%, Titanium Oxide (TiO2) 5.49%, Iron oxide (Fe2O3) 41.64% and other oxides in traces. Firing shrinkage was 4.0%, apparent porosity 17.30%, cold crushing strength 236 kg/cm3, bulk density 2.30 g/cm3, thermal shock resistance 2 cycles and refractoriness of <1200°C. The presence of aluminium oxide and iron oxide has a favorable effect on the clay physical properties. The clay is bentonitic due to its aluminium oxide content. It can be used in the metals industry as a binder for moulding sand for casting metals, as drilling mud in drilling for petroleum. It can also be used in engineering works to seal leaks when mixed with water, as well as for potteries and for the moulding of building bricks. Also because of its attractive colour the clay can be used in paint, chalk and paper making industries.
