Tips and Tricks for making homemade sidewalk chalk…

• Most washable paints will thicken up your mixture in a hurry. Stir well and pack the mixture down tight to avoid air pockets in your chalk
• Sargent Art washable tempera paint makes a smooth liquid mixture – I don’t know why, but this particular paint will make a nice smooth consistency to your chalk
• Silicone molds make great chalk molds because you can pull them away from the chalk to reveal it
• Using disposable bowls or cups to mix the chalk helps with clean up
• Avoid washing your chalk mixture down your drain. Scrape as much as you can off of utensils before washing

You’ll Need: for each color that you make…

• 1/4 cup Plaster of Paris
• 1/8 cup of Warm Water
• 1-2 Tbsp. of Washable Paint – Tempera Paint is preferred *Sargent Art tempera paint is my favorite. It will keep the mixture thin and smooth
• Disposable Bowls or Dixie cups are a good idea
• Molds – I used silicone cupcake wrappers for my mold

Instructions:

• Pour the plaster of Paris and warm water into a bowl or small disposable cup
• Stir in the colored paint
• The mixture will start to thicken up as you add the paint – (I have no idea why the paint addition make it thick, but it’s fun to watch)
• Once you see that the mixture is turning into a thick frosting consistency, then you are ready to shape the chalk
• pour the mixture into your molds
• pack the chalk mixture in so air pockets are filled in
• Let the chalk sit for about 24 hours – making sure it’s nice and dry before you unveil it and then go out and have some fun

Note – *For some reason some Washable Kid’s Paint thickens the chalk mixture way more than normal tempura. It doesn’t impact the recipe, it will just be a thicker mixture and harder to stir. If you want a smooth mixture, I would recommend buying Sargent Art’s washable tempera. I have no idea why it doesn’t thicken the way the others do, but it’s a nice smooth consistency
