Where does clay come from? Clay is a soft, loose, earthy material containing particles with a grain size of less than 4 micrometres (μm). It forms as a result of the weathering and erosion of …

Clay deposits in the glaciated part of Ohio are sediments formed in association with the glaciers of the Ice Age. Clay becomes very hard when heated to a high temperature, so it is used to make …

Clay is more than just a material. It’s a witness to time, shaped by the forces of nature over millions of years. Each piece of clay we touch carries the story of ancient rocks, weathered …

It has been being formed for millions of years, since the time of the glaciers. The main ingredients in clay are alumina, silica and water. In its natural state clay can be easily molded and …
