Buying Guide

Choose dustless or low-dust formulas

Dustless or dust-free chalk reduces airborne chalk particles, making classrooms cleaner and better for students and teachers with respiratory sensitivity

Prioritize high-visibility colors

Luminous and vivid colors improve readability from the back of the room and work better on different board finishes than standard white chalk

Check for non-toxic certification

Non-toxic labeling indicates safer handling for frequent use by teachers and students; look for manufacturer safety information on composition

Buy in classroom quantities

Chalk is consumed quickly in lecture settings—opt for multi-pack counts that provide good value per piece for regular use

Match chalk to your board type

Some chalks perform better on traditional slate/porcelain boards than on matte or textured surfaces, so test a stick if possible for consistent stroke quality
