Upcycled Melted Crayons

This tutorial for upcycled melted crayons will turn your broken crayon pieces into beautiful, unique mosaic crayons. You can keep similar colors together or mix them for a rainbow effect. They would make a cute party favor, stocking stuffer, or gift for a little one.

My mother and I are polar opposites in the kitchen. Cooking often stresses her out because she is the type of person that must follow a recipe to a T. If a recipe calls for 1/4 teaspoon of dried basil, she will stop everything she is doing, run to the store, and buy basil before proceeding to cook. I, on the other hand, look at those situations as an opportunity to experiment. “We’re out of basil? Hmmm…” I think, “I’ll just substitute oregano and see how it goes.” This resistance to following directions is what makes baking a challenge for me.

One thing my mother excels at is party planning. If Pinterest existed when I was a little, my mom would have dominated the kids’ birthday parties boards. Every year, we’d pick a theme and my mom would make sure every detail related to that theme. One year, she threw me a Crayola party and somehow found candles that looked exactly like Crayola crayons. Bear in mind, this was the 1980’s before the internet and Google and Amazon. This was back when you had to look businesses up in the Yellow Pages (raise your hand if you even know what the Yellow Pages are!) and call them to see if they had whatever you were looking for in stock. Then, you had to drive there to pick it up. Nothing was magically shipped to your home within 48 hours for free. Thinking back, I don’t know how she did it; she must have been a magician.

I’ve seen this idea floating around Pinterest for a few years and doing this little project over the weekend brought back those childhood memories. I think these upcycled melted crayons would have made a perfect party favor for my Crayola party back in the day. But, since I am not throwing a kids party any time soon, I decided to make these for my classroom art center. 

My kiddos are blowing through crayons this year at an alarming speed. As an arts academy, we supply crayons for each child to use during rest and throughout the day at their table spots. Usually, we can wait until after the holidays to give the kiddos new crayons, but their supply was running so low, I had to dish out new crayons before Thanksgiving. That’s great though because it means I have a lot of budding young artists sitting in front of me every day! 

Just before break, I had the kiddos sort the crayons by color and measure them. If a crayon was longer than their thumb, they were to put it back in their crayon pack and keep using it. If it was shorter than their thumb, they had to put it into a bowl with the corresponding color.

  • Broken crayons
  • Muffin tin or silicon candy mold


  1. Remove any paper from your crayons and place a mix of colors into your muffin tin until it is about half way full.
  2. Pop your muffin tin into a 325˚ oven and bake for 7 minutes or until crayons are completely melted.
  3. Carefully remove the muffin tin from your oven and set the wax by letting it cool on the counter top for about 15 minutes. 
  4. To remove your new crayons easily from your muffin tin, pop it into the freezer for about 10 minutes and the crayons will slide right out.

*Note: Crayola crayons are non-toxic so you can reuse your muffin tin safely after a good washing. If you are using another brand of crayon for this project, you will want to check with the company or purchase a tin solely for this purpose. 

I can’t wait to see what kinds of things my kiddos make with these new crayons. I also think they would be great to use for Rainbow Writing!
