What You’ll Need:
Silicone molds (make sure they are oven safe to at least 200 degrees)
Crayons – peel off the wrapper. TIP: Use an Exacto knife to cut down the seam of the crayon and the paper should easily remove itself.
1. Break crayons into small (1/2 inch or less) pieces and fill your molds not quite all the way to the top. The wax will melt, and you don’t want it to go over the top edge of the mold – but you don’t want to put so few crayon pieces in that they shrink into a teeny thin crayon.
2. Place your mold into a preheated 200 degree oven for about 20 minutes. I usually start checking on mine around the 15 minute mark. You’ll know they are ready when the wax is completely liquified and no longer lumpy.
3. Remove from oven at let cool for a couple of hours. Carefully and slowly, pop the crayons out of the silicone molds to avoid breaking them.
4. Let the coloring fun begin!
*You can mix different color crayons for a fun rainbow colored crayon.
*You can swirl the melted wax with a toothpick to make designs in the crayon before it cools.
DO NOT try to melt crayons in the microwave – this is a fire hazard!
*You can melt crayons on a flat baking sheet and use cookie cutters to cut out shapes once the wax cools a bit and starts to harden.
*You can use metal molds (be sure to spray with cooking spray first), but it just isn’t as easy to pop the crayons out of those. Silicone is much easier to use.
*Crayola brand crayons have worked best for me. However, Washable Crayons will not work for this project!
Here are some samples of crayons I have made in the past with my Star shaped mold, some Lego molds (we used them as Lego-themed birthday party favors), and a Flower shaped mold. We have also used mini-muffin molds to make circle shaped crayons. The possibilities are endless!
