The word chalk comes from the Latin word âcalxâ. We get chalk from limestone. Most of the chalk you find today was made almost 60 to 100 million years ago. It is chemically made of calcium carbonate.
Crayola manufactures two types of chalk, extruded and molded. Extruded chalk, such as Crayola Anti-Dust White Chalk, primarily contains calcium carbonate. Molded chalk, such as Crayola Children's Chalk (available in white or colored), is a softer chalk, and is not dustless. This type of chalk is recommended for children's chalkboards as well as construction paper, cardboard boxes and paper bags. Crayola Sidewalk Chalk is a molded chalk that is not intended for use on chalkboard surfaces. It does not include calcium carbonate. This product contains plaster of paris which has a gritty texture and may scratch your chalkboard.
