What is Colored Chalk?

Colored chalk has the same ingredients as white chalk (calcium carbonate) but before the water is added, the manufacturer adds pigment and then cures and bakes the chalk sticks.  he primary source of chalk in the USA is limestone. Pastels chalk, however, is made with calcium sulfate instead of calcium carbonate.

How to Make Colored Chalk

Making chalk with colors is fun and not that difficult. This method uses just 3 ingredients.

Here’s what you’ll need:

You will use 2 parts water for 3 parts plaster. The amount will vary based on the size of the molds you use. Below are steps when using a smaller mold.

  • 2 tbsp water
  • 3 tbsp of plaster.
  • Add 1/2 teaspoon of tempura powder paint per color (6-8 drops of food coloring).
  • Mix well. You can add drops of water if the mix is dry.
  • Put in mold of choice (silicone works well).
  • To fill in any gaps in the mold, leave about 1/8 inch free at the top, and and add a final layer of watery mix. You can achieve this by adding water to the mix. This will fill in any gaps in the mold.
  • Allow to dry for a minimum of 12 hours.
