Clay is not really made by people. It is a group of minerals that are found in the soil and other deposits. It ususally occurs as a very fine textured substance which gives it its sticky properties. There are many different kinds of clay and not all will make good building material. The indigenous peoples would have used natural depostis of clay, moistened with water to make it workable and then possible added straw or other fibrous material to act as a binder and keep it strong. You may be able to find some clay if you cantact a brick manufacturing company in your area. Explain to them what you are doing and they may give you some of the clay that they use to make bricks.
