Chalks are utensils that can entertain children a lot, but they are also useful for learning, so they can be used to play in the yard or at home or to be used on the blackboards in the classroom. It is also a product that can be easily made at home, so there is no excuse for not having chalk always available and to allow the little ones to put themselves in the shoes of their teachers in front of a blackboard, something very typical of the game imitative.

There are different homemade ways to make chalk , but today we will focus on two particular ways: one in which plaster is necessary and which is an activity suitable for children and adults, and another special recipe for the smallest of the house and for allergy sufferers, as it is a recipe to make biodegradable and non-toxic chalk.






Homemade chalk with plaster

This, in particular, is the traditional way of making homemade chalk and is certainly more recommended for children from elementary school and up, and always in the presence of adults (not for very young children). To carry out the recipe we will need half a cup of plaster, tempera of the color you want the chalks to have, dishwasher soap, waxed paper to prevent the chalk from sticking to the mold, a mold (which can be made of plastic or cardboard) to give the shape to the chalk and a container to make the mixture.


Steps to make the plaster chalk

  • Place the waxed paper in the mold chosen to make the chalks. Make sure the waxed part is in contact with the chalk.
  • In a container add half a cup of plaster, two tablespoons of paint or tempera of the color you want and two drops of dishwasher soap.
  • Mix the plaster and paint well until you have a smooth mixture.
  • Pour the mixture into the molds and spread it with the help of a spoon.
  • Cover the mixture with wax paper.
  • Place the mold in a dry environment and wait for it to fully solidify , about 12 hours.
