Our lives are rooted in soil! Soil is all around us and artwork is no exception. From the clay molded and used in pottery to beautiful paintings, soil has always played a big role.
Many of the materials used in the making of traditional artwork are found in the earth’s crust. These include soil for color pigments used in paints, dyes, and inks; rocks for sculptures; sands and minerals to create glass; ores for metalwork; and clay for ceramics. Soils are also critically important in growing plant materials for textiles and wooden objects.
In the Stone Age, natural pigments like red and yellow ochers and magnesium oxides were used for pottery, houses, and body paint for rituals. One Dutch painter, Hieronymus Bosch, used earth and soils as the main subjects of his paintings to evoke deep religious symbolism and meanings. His most famous and controversial piece is the triptych Garden of Earthly Delights, which portrays people living off the bounty of the earth. More recently the Land Art Movement began in the 1950s focused on soil. Soil profiles can show stark contrasts in colors, layers, and textures, making for beautiful art.
In pottery, specifically, there are three general types of clay that are used. Porcelain has as its main ingredient a clay type called kaolin. Although it is durable, it can show signs of wear if not careful. Day-to-day plates for dining are made from stoneware clay. Earthenware clay contains a wide variety of minerals, including things like iron oxide.
