This is an easy tutorial for robot shaped crayons only because we were having a robot-themed birthday. It’s really for any kind of shaped crayons – the possibilities are endless. All you need is a few boxes of regular crayons, a silicone mold and an oven.

Step 1: Peel all the wrappers off the crayons. It’s tedious, but put on a movie, grab a glass of wine and get to work.

Step 2: Break the crayons into pieces. For the 1 inch molds we broke each crayon into 3 or 4 pieces.

Step 3: Put broken pieces directly into the silicone mold.

Step 4: Put the mold in an oven or toaster oven set at 350 degrees for approximately 5-7 minutes, or until the wax has melted.

Step 5: Carefully transfer the mold to a shallow dish filled with ice water. Once the wax cools and hardens, pop out the crayons and repeat!

Lots of colors! Erin made a whole rainbow – each kid got at least 8 crayons.

Tips:

• We were looking for a way to melt the wax to pour into the molds when I suggested just melting the wax IN the mold. It worked perfectly, and all the details on the crayons showed up really well.
• This is the silicone robot mold we used for the crayons. It’s technically for chocolate, but any silicone mold would work for crayons.
• Wax DOES burn, so keep an eye on your crayons and don’t try to rush them by turning the oven up too high.
• If you set your mold on a piece of tin foil (see below) the foil cools almost instantly and it’s easy to transfer to the cold water without tipping or sloshing the wax.
• We only filled the molds about half way – it kept the crayons easy for little hands to grab.

Crayons in action!
