I wanted to try making homemade sidewalk chalk for quite some time. I found this recipe, but I changed it a little bit (instead of powdered tempera paint, I used the liquid one).
The whole process seemed intimidating to me and I thought it’ll be a lot harder than it actually is. For some reason, I also thought the homemade sidewalk chalk is going to be of lower quality than the commercial ones, which also happens to be false! 🙂
First you need some toilet paper cardboard tubes, which you cut in half and then tape the new edges together with a piece of sticky tape. Then seal one end of the tube with some more sticky tape. Insert some baking paper and then use the exact method to make 3 more tubes, since the recipe yields about 3-4 chalks of desired color (depends on the size of the tube used).
Fill a regular glass (200 ml) with water to about 3/4 and pour it into a larger bowl. Add the tempera color of your choice and adjust the quantity of the paint, depending on how strong of a color you want. I only used one tea spoon of color. Now mix it well and make sure the color is fully diluted in water. Then add 1 full glass of plaster powder and mix it thoroughly.
Carefully pour the mixture into the tubes you’ve prepared until each tube is full (I used a spoon to make things easier). The mixture starts to harden quickly, therefore its not good to wait before pouring it into the tubes. Place filled tubes in an upright position – ideally into a larger cup so they can’t fall over while hardening.
In about an hour you can remove the card board tubes and the baking paper.
I recommend you leave the chalk to fully dry on air. Although you could just leave them to dry inside the cardboard tubes, it’ll take much longer.
The chalk will dry a lot faster on air so you can start using them in about two hours. 🙂
I used the most tempera color in the red chalk, which gives it more intensity. I also noticed that the red chalk leaves quite a bit of color on your hands while others did not (no any more then regular chalk anyway).
Now just head outside and make the world just a tiny bit more colorful! 😉
