Clays

Clays are diverse natural materials formed over millions of years through the weathering of rocks and minerals, primarily composed of fine particles like kaolinite, illite, and montmorillonite. Rich in minerals such as silica, alumina, iron, and calcium, these clays vary widely in color, texture, and taste—from smooth, creamy whites to dense, earthy reds and browns. Throughout human history, clays have played a vital role not only in pottery, medicine, and construction but also in geophagia—the practice of consuming earth for nutritional, medicinal, or cultural reasons. Many cultures around the world value edible clays for their mineral content, detoxifying properties, and soothing effects on the digestive system. Whether enjoyed raw, roasted, or mixed into pastes, global clays connect us deeply to the earth and continue to serve as a natural source of nourishment and tradition.
