How to Make Chalk

Pin It


  • 1/4 cup warm water
  • 1/2 cup plaster of paris
  • 2-3 TB washable tempera paint
  • Candy molds/ice cube trays (found mine at ikea)
  • Useful to have on hand:
  • Disposable bowls
  • Plastic spoons
  • Paper towels or newspaper


  1. Combine warm water and plaster of paris in a small bowl. Stir with spoon until clumps are removed.
  2. Add paint and stir until combined.
  3. Once the chalk starts to get thick (like butter cream frosting) pour mixture into molds.
  4. Wipe around the edges of the mold with a damp paper towel to remove any excess paint.
  5. Allow chalk to dry for at least 24 hours before using.
  6. Take your chalk outside and let your kids go wild!
