  In this study, our objective is to describe some properties of Wasia Formation clay as raw materials in various ceramic applications. Clays were analyzed by X-ray diffraction, chemical composition and plasticity. The data collected from these techniques show that the kaolinites are major clay phases. The main oxides in the clayey samples are SiO2 (51-53%), Al2O3 (26.0-28.0%), and Fe2O3 (2.0-3.0%). The accessory minerals detected in the powdered rock are; quartz, dolomite and hematite. This study reveals that the amount of silica is relatively high and a plasticity test shows a medium value. Geotechnical characterization was carried out on the three representative samples of Wasia Formation. Samples were pressed in a rectangular mould and sintered to a temperature ranging from 850 to 1000°C. Firing characteristics (shrinkage, water absorption, loss of ignition, and mechanical resis..
