Crayola® manufactures two types of chalk, extruded and molded.
Extruded chalk, such as Crayola Anti-Dust® White Chalk and molded chalk, such as Crayola Chalk (available in white or colors), are 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. This product has a gritty texture and may scratch your chalkboard.
