There are those who imagine that prehistoric people were semi-humans who walked with their heads bowed, grunted like pigs, and had hair growing in unusual places.

There is no doubt that there are also those who object to the title with which this chapter begins. The word prehistory refers to what preceded written records. If we define science as the organized recording and interpretation of observed phenomena, then prehistory is what preceded science, and the expression prehistoric chemist combines two contradictory terms. To begin our story, we must jump to the first millennium B.C. If we were to adopt this view, we would be at a great loss: for in the beginning, there was no need for pen and papyrus, which are necessary for the beginning of the art of chemistry. Prehistoric peoples threw small pieces of rock into the fire and observed the resulting color changes, and this was a true practice of chemistry. They and their civilized descendants collected a stock of chemicals, techniques, and observations on which later developments were built. They used paint, controlled fire, made pottery, collected and manufactured metals, and practiced the arts of healing and treatment. We will expand here on some of these achievements because they are of a chemical nature, meaning that they involve observing the properties of materials and what happens to them when they interact.
