DIY Recycling Crayons


I was one of those kids that took my Crayola box everywhere I went. My mom even tells this story of how I drew my first crayon scribble before I learned how to talk. I’m not exactly sure of the verity of that tale, but it sure makes me feel special, but only when my mom tells it!


Anyhoo, as an avid Crayola-ler, I have more than a spare share of boxes running around the house, filled with every color imaginable. And like most creatives, big or small, I usually get a bit discouraged by ugly looking old crayon + their horrid broken tips. Reason why I had to whip out this DIY Recycling Crayons tutorial during my last TV segment at Tu Mañana.


Super easy + so much fun to make, this DIY is a fantastic crafty project idea that parents + teachers + crafty folks out there can use to say good bye to broken crayons + hello to brand new beautiful looking ones in no time.



For this project you’ll need:

  • Crayons (old or new)
  • Silicon molds (I used a number mold, but you can use any shape)
  • Exacto knife
  • Pirex


step by step

After you’ve gathered your materials…


Step 1: Preheat oven to 250°F



Step 2: Peel all paper from crayons.


Step 3: With the exacto knife, break the crayons down to smaller pieces so they can fit in the pan.



Step 4: Fill pan spots with the broken crayons pieces. Mine are one color each, but you can play around with this for wackier outcomes.


Step 5: Put your tray inside a pirex before putting inside the oven. Believe me, you don’t want to be cleaning your crayons spilled stove later.


Step 6: Bake for 10-15 minutes making sure not to over bake the crayons, specially if you’re mixing many colors together. These will melt together + it will look nasty. Been there, done that.



Step 7: Let crayons cool + solidify for a couple of minutes + then put into the freezer for 30 minutes or until they’ve harden.


Step 8: When their firm, pop them out of the mold, like you would an ice cube.



Step 9: Listo! Bring out your inner Picasso + start the crayon bonanza!



  • Please use silicon molds. Plastic melts when you bake it. Not pretty.


  • Crayons are just like candle wax, when they melt, they’re hot. And I mean REALLY hot. So, please, when taking your crayons out of the stove use protective oven mittens for safety.



For an awesome variation, check out this awesome DIY Rainbow Crayon I stumbled upon over at Paper N’ Stitch. It’s totally fab.

    This is such a resourceful way to recycle crayons & they’d make awesome gifts & party favors! My toddler thinks it’s fun to break his crayons so this would be a perfect solution for all the pieces that are too little to color with anymore! Thanks Mayi! You’re awesome!

    Meagan: Ohh yeahhh, these would make adorable party favors. I still don’t have any kids running around the house. It’s just me, but that’s already enough to have the home filled with broken crayons. But of course I’m dreaming of the day when I get to have my own little artist running around here! Oh boy, I’m getting emotional!

    I’m a kindergarten teacher and this looks like a great way to recycle all the crayons that get broken and left at the bottom of the art trolley. Thanks so much for sharing. Also, some types of crayons can be cleaned with a soft cloth with cooking oil on it.
