Have you ever wondered how to make make new crayons out of old crayons? It’s actually super easy to make crayons in silicone molds. If you have some old crayons laying around grab them and let’s repurpose your broken crayons into new ones.
I’ve heard that Crayola brand crayons work best when remaking crayons, but I used a variety of whatever was in the bottom of our arts and crafts supply bucket with no problem.
Supplies you’ll need to make and melt the crayons
- Broken crayons
- Silicone mold of your choice
- Aluminum foil
- Non-stick cooking spray
- Baking sheet
How to make the crayons in silicone molds
Printable instructions below
To make the crayons, begin by removing all the paper from your broken crayons. Once you have your crayons break them into small enough pieces to fit in your mold. Spray your silicone mold with non-stick cooking spray (this will make them much easier to get out when they’re cooled).
I used similar colors in each individual mold for my crayons but you can use whatever colors you want. Mixing colors is a fun option. I did try to avoid using black and white crayons with other colors.
Cover a baking sheet with aluminum foil and place your silicone mold on it. This will prevent any melted crayons dripping in your oven or spills when you take them out. Bake your crayon pieces at 350 degrees for 8 to 10 minutes. You’ll want to check and make sure they are melted completely since your oven or mold might require more or less time.
Next, let them cool for a few hours and then carefully remove them. They should be easy to remove thanks to the cooking spray.
What mold to use
I used a silicone mold from Amazon. My mold was kind of chunky but I love how bulky the crayons turned out with it! They are perfect for chubby little toddler hands or preschoolers who are still learning how to write. My son used these crayons when we did our V is for vegetable learning activity.
If you have other fun molds, go for it. Alphabet crayons are a super popular party favor these days. I’ve also seen some cute emoji face ones too. There are all kinds of fun ones available on Amazon. Whatever one you decide to go with, definitely be sure to use a silicone mold and spray it with non-stick cooking spray before baking your crayons.

This sounds fun! I saw a kids youtube video about this, and I’ve been meaning to try it. Thanks for the reminder!

This is so funny and really quite simple. I’ve been thinking about doing it with a star shaped silicone mold that I happen to have at home!

Great project for the kids! And a great way to use what you already have to make something new!
