Black figure painting: The original technique, used by the Greeks for creating forms/silhouettes using black paint on terracotta clay. Before firing, they would paint on a black slip (profiles only), and then fire it several times. Red figure painting: This method replaced black figure painting. It was considered superior because more detail could be added. Red figure painting is the reverse of the black figure technique. The paintings were applied to the shaped but unfired vessels after they had dried to a leathery, near-brittle texture. Hope This Helps!
