red chalk
Terra cotta crayon
Red chalk is a reddish-brown drawing medium made from iron oxide–rich clay, used since the Renaissance for sketches and studies.
Artists favored it for rendering flesh tones and subtle shading: Leonardo's red chalk drawings of the human figure.
The term covers both the raw mineral and the fabricated sticks or pencils made from it.
