The main objective of this paper is to study the mineralogical composition and the environmental conditions of the Subiyah clay to be used for crafting pottery and technological behaviour that allows the evaluation of the applicability of the clay deposits in manufacturing new ceramic products at Kuwait. This research could help artists, crafters of potters, and ceramic manufactures in Kuwait to depend on inland clay and this makes it easier for more production in ceramic and pottery in the future. All this could enhance the cultural of ceramic in teaching or producing it in Kuwaitfor the first time. For that purpose, six stations were selected at North-eastern part (Subiyah area) of Kuwait for clay investigation. X-ray Diffraction method (XRD) was led to identify mineralogical composition of samples; S1, S2, S3, S4A, S4B, and S6 were quartz, Calcite (Caco3), Dolomite, Illite and Clinochlore. Whereas; Quartz, Calcite Dolomite, Palygorskite, Nontronite and Clinochlore were recorded at S5 and S7. Clay mineralogical and environmental studies at our study area proved that, crafter can depend on Subiyah clay better than importing it from abroad.
