Red Chalk historically is made from which materials?

• A. Charcoal
• B. Iron oxide pigment and refined clay
• C. Graphite
• D. Calcium carbonate

Answer: (B)

Red Chalk is a drawing material that relies on iron oxide pigment and refined clay. The iron oxide gives the distinctive warm red color, while the clay provides body and a soft, powdery texture that can be formed into sticks and easily blended on the paper. This combination creates a smooth, erasable yet rich shading tool, which is why artists historically favored it for portraits and skin tones, often called sanguine.

Charcoal would produce a black color and a dusty texture, graphite yields gray tones, and calcium carbonate is white, so none of those materials would give the characteristic red hue and blendable quality of red chalk.
