Recycled Crayons: Mixed Hearts

There may be nothing new about recycling crayons (after all, my mom was doing it in the 50's), but there's something about molding something old into a new version of itself that's so

This project is a usable, versatile craft for all ages. The finished product makes great teacher gifts, favors for birthday parties, or back-to-school treats for the kids. Have fun experimenting with different color combos and tray shapes--I personally, have my eye on on a robot ice tray for our next batch--and use this opportunity to chat with your children about everything from the basic chemistry of wax properties changing, to where colors fall on a color wheel. Have fun!


Unwanted Wax Crayons (wrappers removed)
Silicon Ice Cube Trays OR
Candy Molds
Plastic Cups & Wood Skewers (microwave version only)


Microwave (Solid Color) Version:

  • Combine like color pieces, into sacrificial cups (trust me, you won't want to drink out 'em after they've been crayon'd!).

  • Cook in microwave until melted (about 5-9 minutes); stirring with skewer, as needed.


  • Pour melted crayon into candy mold. Work quickly, because the wax thickens fast!


Oven (Marbled) Version:

  • Break crayons into small pieces.

  • Place pieces into a silicon ice tray. Kids love being a part of this process, because they can mix & match colors to create their own, little works of art! (My son Tristan, filled the two bottom hearts with colors to look like "camo" and "sand camo". Boys.)


  • Bake in oven at 250 degrees for 20 minutes, or until crayons are completely melted. Carefully remove from oven, taking care not to spill the hot wax.

    Both Versions:

  • Place trays into freezer for about 30 minutes to harden.

  • Pop your crayon creations out of the trays and enjoy!

AMAZING! Here I was, googling ideas for Madelyn's tie dye birthday party and I switched over to check the facebook haps and saw this post!! The perfect tie dye party craft. woooo hooo! Any special molds that can go in the oven or are they all oven safe? We don't have a microwave.

As always, you are awesome and love the recycling!

No microwave, you can usually find one pretty cheap at a good will store!

Thanks so much! Pamie G. New Braunfels

I can smell the crayons now! lol I did something like this when I was a kid. I'm glad to be reminded of it. I might try it this week with my kids and post pictures on my website: Thanks for the great idea!

Michelle writes...

These are great - love the bright colours and how you have marbled them without creating a mucky mess!

Jon writes...


I think you should suggest a glass container, because my plastic cup melted in the microwave and spilled hot wax on my hand.

Love this IDEA!!! I'm a Pre-school teacher and the end of each school year we end up with a stack of half used crayons that nobody wants! I'LL BE COLLECTING THOSE THIS YEAR =)!!!

I did onesimilar using the crayon pieces between layers of waxed paper and ironing it to create a colorful 'stained glass' effect. Also no spills or burns.

Chelsey writes...

I am a nanny and do this all the time with my children. They love to do it!

My grandmother did this with me as a child only she used dixie cups and candle wicks to create candles

Wow! What a nice stuffs you’ve made. Thanks for the details.

Oh, how sweet! I love the way you did this. I recently featured the same process on my blog, but my super crayons certainly weren't adorable shapes like yours! I must certainly keep this in mind if I make them again.

Super Cute! Now I know what I am going to do with those 100 boxes of 16 count crayons I have. (I needed 8 counts they are CRAZY expensive, but crayons were on sale at back to school!!!! :-P)
