Clay Category
Clay is a natural earthy material composed primarily of fine-grained minerals such as kaolinite, illite, and montmorillonite. Its plasticity when wet allows artists and builders to shape it into pottery, bricks, and sculptures with ease. Clay's ability to harden upon drying or firing makes it an essential resource in ceramics and construction industries. Rich in alumina and silica, clay also supports agricultural soil improvement by enhancing moisture retention.
