DIY Recycled Crayons- How to Melt Crayons in an oven

If you are a parent to a toddler or a preschooler chances are that you have crayons coming out of your ears. In our house we have crayons of every shape, size and brand possible. The biggest problem is that after a little wear and tear, kids are no longer interested in them. To boot new crayons are always coming in the household thanks to birthday gifts, returns gifts and so on. So you have a lot of crayons at hand which no one uses and yet you don’t feel like throwing them away. What to do with old crayons then?


When my daughter’s box of stubby, peeled off, old, broken crayons started to get full, I decided to look for some ideas on recycling them and that’s when I found the perfect recipe to melt old crayons in the oven and get brand new ones. This is also a part of our list of 40 summer vacation activities and ideas for kids.

How to Melt Crayons

Firstly peel off all the paper from the crayons. This can be made easier if you just soak them in warm water for  a while. After they are dry just break them into medium sized pieces. You can get your kids to do this with you. Once all the pieces are broken then you have the choice to either sort them into various colors or like us you can go for multicolored crayons.

For melting the crayons you can either use mini-muffin tins or use silicon moulds like we have used. Only thing to keep in mind is that once you have used the moulds to melt crayons please don’t use it for baking purposes and keep them aside for craft activities only.


We have a convection microwave oven in our house and that is what I used for melting the crayons. I preheated my oven at 180° C and then kept the moulds (on top of a baking tray) in the oven at 250°C for 10 minutes. Once the time is done take the moulds out (please do this yourself and use oven mitts) and give the melted crayon a bit of a swirl with a toothpick. This will ensure the swirly patterns you see in the crayons.

Keep them to cool for around an hour or so. Once cooled pop them in the freezer so that they set properly. (caution: don’t keep them in the freezer when they are hot because that will cause them to crack) Keep them overnight and in the morning unmold to get brand new multicolored crayons.

They looked so cute that my daughter thought that I had somehow baked some multicolored muffins and kept asking me whether I was sure that they were not edible.

You can also melt the crayons and then pour the melted crayons into cookie molds to get shaped crayons. You can’t see in the pictures but we also added glitter to our melted crayons so when the kids scribble with them there is a glittery effect.

For Samaira I am the cool mom who can turn her old boring crayons into colorful glittery chunky crayons. For me I get to recycle something that would have otherwise gone to waste. It is a definite WIN-WIN for everyone!

Melting crayons and recycling them is a simple and easy process so do try it at your home and give your kids some adorable looking crayons to play with. If you have made them earlier and used a different method so please let us and the other readers know through the comments.
