Like every family of three, we had boxes full of broken crayons. I debated throwing them away, but then my sister told me about her crayon making at home. It was super easy.
We took all of the partial crayons, and the kids spent the afternoon peeling the paper off. They then crushed them with a mallet in a plastic bag.
We put them in a bag and used a mallet to break them down a bit. Then we put them in silicone candy molds. It works best if you arrange the colors of similar types together.
Turn on the oven to 250 degrees. Put the candy molds on a foil lined cookie sheet so it catches any spills. Put tray into the oven for 20 mins. If you want more well blended colors, stir the melted wax with a skewer once it is melted. The melting will cause the crayons to shrink down into the mold, so add more crayons if you want a large final product.
Take tray out of the oven and let rest for about 20 minutes on the counter. Once it is partially cooled, you can place in the refrigerator until they are set.
Carefully pull the sides away from crayons and then pushed firmly directly upward until the entire crayon is free.
