Answer:
Tempera
Step-by-step explanation:
Tempera, which comes from Latin (temperare) means to mix or coalesce, is the oldest paint we have. It was used in antiquity, the Middle Ages and the Renaissance, on the murals of the dynasties of Egypt, Babylon, Greece, China, and early Christian art decorations.
Most of the time, it was produced by the artists themselves. Few manufacturers marketed inks for this technique. In fact, each had a way of producing.
