Bookmark Glossary Terms Humans have always used materials from the earth selectively. Early human artists who painted on rock walls made their own paints from red and yellow pigments present in soils pigments we now know as the minerals hematite and ochre. Countries have fought wars and trade companies battled over deposits of table salt also called halite in the East Indies.
