Chalk Making

Chalk making is the process of creating chalk, typically used for writing on blackboards or for sidewalk art. This craft involves making a mixture of materials that harden into a usable chalk form.

Description and How to Do It

The basic process involves mixing calcium sulfate (gypsum) or calcium carbonate with water and a dye for color, then pouring the mixture into molds to set and dry. It can be a fun and educational activity, teaching about basic chemistry and crafting.


  • Scientific Learning: Introduces basic chemical processes and materials science.
  • Creativity: Allows customization of colors and shapes.
  • Fine Motor Skills: Enhances dexterity through the molding process.
  • Eco-Friendliness: Can create non-toxic, environmentally friendly chalk.

Best Age to Start

Children can participate in chalk making from the age of 8 or 9, with adult supervision to ensure safety with materials and measurements.


  • Websites: DIY crafting sites for recipes and ideas.
  • YouTube: Channels that focus on homemade crafts and educational activities.
  • Books: General crafting books often include sections on homemade art supplies.
