What You’ll Need
- Old crayons (I prefer Crayola because I think they color the best)
- Minifigure Silicone Mold (You can get the molds on Amazon)
- Cookie Sheet
Step 1: Peel the Crayons
Once you’ve collected your wayward crayons, you’ll have to peel them. If you’re like us, these crayons have been stuck in a ziplock bag sad, broken, an unused for some time.
Peeling the crayons is a great way to get the kids involved. There will be little bits of paper everywhere but it’s surprisingly fun to do.
Step 2: Break up the Crayons
You can put them in a baggie and smash them or just break them by hand. If you’re using the large crayons it’s easier to smash them up a bit. The smaller pieces fit better into the molds.
Step 3: Preheat the oven to 150-200 degrees
You want your oven to be a low enough temperature to gently melt your crayons without taking a really long time to do so.
I read on the internet that you should melt them at 150 degrees for 15 to 20 minutes. My electric oven doesn’t go that low. I started it on 170 degrees and it took forever to melt the crayons.
Eventually, I put it on 200 degrees and it took about 15-20 minutes to melt the crayons down.
Step 4: Put the Crayons into the LEGO Minifigure Molds
When you put the crayons in the molds you want the crayons to stick out a little. As they melt, they’ll fill in the gaps and you’ll have less than you started with.
You can choose to use all one color or mix colors for fun designs. I like doing some of both!
Step 5: Put the Mold into the Oven
When you’re ready to put the mold into the oven, set it on a cookie sheet. This makes it a lot easier to get in and out of the oven and removes the chance of wax melting into your oven.
Keep the mold in the oven until the wax has melted. If your mold isn’t full, you can add more crayons and continue melting.
Step 6: Take it Out of the Oven
Grab an oven mitt and carefully pull the tray out of the oven. Set the tray down evenly to avoid spilling melted wax. Let the melted wax begin to cool before moving it again.
Once the wax begins to form, I put it in the freezer to speed up the process. I only have one mold so it was a little slow going. If you plan on making lots of them, I suggest purchasing several molds.
Step 7: Remove the Crayon LEGO Minifigures from the Mold
The final step! Once the crayon LEGO Minifigures have completely cooled, you can remove them from the mold.
Make sure they’re FULLY cooled. If they’re not completely solidified it’s a lot easier to accidentally break off their little heads (I know from experience). Gently remove them from the mold paying careful attention to the heads and feet of the Minifigures.
