Highly Pigmented Blackboard Chalk for Drawing, Writing, and Chalk Art

Mercurius blackboard chalk is an artist-quality chalk made from natural calcium carbonate and pure pigments, designed for clear writing, expressive drawing, and layered chalkboard work. It offers rich color, smooth application, and reliable performance for both classroom use and artistic practice.

The balanced composition allows the chalk to glide easily across the board while maintaining enough structure for lettering, form drawing, and detailed illustration. Colors blend cleanly and release evenly, supporting techniques such as shading, soft transitions, and layered chalk drawing.

Designed for Teaching, Drawing, and Daily Use

Developed for educational and artistic environments, this chalk performs consistently across a range of uses:

• chalkboard lessons and writing
• form drawing and geometry work
• seasonal chalkboard art and illustration
• blending and shading techniques

Its natural composition avoids synthetic fillers, allowing for a clean, vibrant mark that can be easily worked and adjusted.

Chalk Options

• 16-Color Assorted Set – A full range of colors for drawing and illustration 
• 12-Count Single-Color Packs – Individual colors packaged in 12-count boxes for refills and focused use

Chalk Drawing Tools

For greater control during chalk drawing, this chalk is often used alongside a textured cotton blackboard cloth, which allows pigment to be lifted, softened, or shaped directly on the board.

Shipping & Handling Note

The softness of this chalk is part of what makes it such a joy to use—it blends and layers beautifully—but it also means we cannot guarantee that pieces won’t crack during transit. We will wrap it carefully to help minimize the risk, and even if a piece arrives cracked, it will still draw, blend, and paint just as beautifully.
