Recycled Crayon Tutorial

Gather your supplies.

Peel your crayons (this is the pain in the butt part!). Separate crayons by color.

Put each color in its own can. If you mix them in this step, you’ll get an ugly brown color.

Preheat oven to 300*F.

Put cans of crayons on a cookie sheet, just in case they spill. Trust me, melted crayon stuck to the oven does not smell good.

Bake for 10 minutes, longer if necessary. The crayons will be liquid when they’re ready to use.

Quickly and carefully pour your crayons into the molds you have set out. Spray them with cooking spray ahead of time if you find they are sticking. You can use silicone molds, or plastic candy/chocolate molds for this step.

After about 15 minutes, set the crayons in the freezer* to harden if you’re in a hurry. Flip the mold over and the crayons should pop right out.

*Note: This can make your crayons brittle, so if you have the time and patience to let them sit out on the counter and cool, do it that way.

The best part about this project is finding different molds to use. I’ve made crayons in every shape you can imagine – from brains to princesses, we’ve used lots of recycled crayons in this house!

To get the supplies, visit Amazon for the best deals!

I paid $19.99 a piece for these Lego Man molds but it looks like they’re on sale for $9.99!

    What kind of molds did you use?

    I just made little lego guys for my son to give away as valentines. Instead of putting the mold in the oven, we put it in the microwave for 5-8 minutes, until the wax was melted. It worked great!

  10. We did this years ago, but the Lego molds are inspiring me to do it again! …Or maybe just buy chocolate melts and let the kids eat lego guys, lol.

    Hi, did you use the “ice-cube tray” to make the Lego men? I read on a different website hers melted!! Then again she was melting the crayons directly inside the tray…

      If you click the link to the tray in the post it’s the exact one I’ve used dozens of times – and no melting! :) It’s a special material, not like regular ice cube trays that are made of plastic.

  12. This is just impressive, and kids can do this with adult supervision. Really cool!

  13. These are the cutest things ever! I love your idea. Thanks for sharing you great post at Together on Tuesdays :)

  14. What a great way to recycle all those old broken crayons!
    Thanks for sharing with my NO RULES Weekend Blog Party!
