Latin America, especially Mexico, offers a rich tradition of earth-derived materials used both for art and consumption. Mexican terracotta clay, commonly used in traditional pots, figurines, and cookware, is known for its rich reddish hue and deep, sun-baked aroma. Some varieties of barro (Spanish for “clay”) are naturally earthy, slightly gritty, and occasionally used in geophagy, offering a warm, mineral taste with a rustic, baked-soil character. These clays often retain the scent of fire or smoke due to traditional open-pit or wood-fired curing methods. In regions like Oaxaca and Chiapas, natural grey and red clays are also found, sometimes used ceremonially or consumed for their grounding, earthy textures. These clays reflect the volcanic and mineral-rich soils of Central and South America, carrying with them centuries of indigenous craft and cultural reverence.
