Red ochre is a natural earth pigment made from clay that contains iron oxide, giving it a rich red color. It has been used for thousands of years in art, decoration, and even in rituals. This pigment is often found in various geological formations and can be processed into a fine powder for use in paints and dyes. Historically, red ochre has been significant in many cultures, including the Cave Paintings of prehistoric humans, where it was used to create images on cave walls. It is also associated with burial practices, symbolizing life and death in various ancient societies.
