A smooth, soft chalk with strong colour pigments. Pastel-like in application, the colours have a high coverage and are easily blended on the board. And the pigments are 100% Natural!

What makes Mercurius Chalk different?

Chalk is not an uncommon product, and will normally contain common ingredients including Calcium Carbonate, pigments, and fillers. Getting the right formula is what differentiates chalk!

This is why Mercurius has taken over 12 months to reformulate our chalk! Not all Calcium Carbonate is the same, and pigments come from a variety of sources - both natural and synthetic. Mercurius Chalk uses a high-quality form of Calcium Carbonate with quality all-natural pigments, limiting the need for additional fillers and creating all-natural chalk. 

The result - a high quality, natural pigmented pastel chalk, answering to the demands of the blackboard artist and meeting all current worldwide safety certifications for child health and use in the classroom!
