How to Make Eggshell Chalk?

This activity allows you both to spend time with your child and to make him aware that you can make things instead of buying them. However, make sure your child is not allergic to eggs before starting the activity.

We need :

• well-washed eggshells with soap and water (to prevent salmonellosis);
• a pestle and a mortar to grind the eggshells (you can also crush them with a bowl);
• plaster of Paris or flour;
• of water.

Well-cleaned and dry eggshells can be stored for a long time. Collect them so that you can prepare a large amount of chalk.

How to do?

• Altogether remove the membrane from the eggshells.
• Grind the shells until a fine powder is obtained.
• Mix 2 parts of flour or plaster with one part of eggshell powder.
• Add enough water to form a hard paste.
• Shape the dough into sticks.
• Cover with plastic wrap and allow it to dry.
• To make colored chalks, add powder paint before pouring the water.
