All Crayons Are Not Created The Same

I am all about taking the cheap way out for most things, but I am a firm believer in Crayola brand crayons make the best DIY melted rainbow crayons.  Disregard the generic crayons seen above.  Some crayons quickly melt into a muddy puddle, also avoid washable crayons at all costs.

Don’t Over Melt The Crayons

Keep a close eye on the temperature of your oven and how long you melt your crayons.  Every oven and toaster oven are slightly different.  If you over melt colors will bleed together no matter what type of crayon you use.

Also, be careful using silicone molds.  Take it from someone who had to throw away a toaster oven.

The Smaller the Pieces of Broken Crayon the Better

I like my melted crayons extra colorful and you get that look using as many small bits as possible.  The smaller the pieces and the more random the colors in each muffin the better your DIY rainbow crayon will be.

Mix Light and Dark Crayons Together

Speaking of random try to include a good mix of lights and darks when melting crayons.  I even go so far as to strategically place crayons next to each other.  Trust me, you’ll thank me later.

Line the Cookie Sheet

I had an unfortunate incident at my old house making DIY rainbow crayons and forever after the oven smelled oh so slightly of crayons.  Line a cookie sheet with foil and then place your mold on top of that to protect from any spills.

Do Not Move The Melted Crayons Too Much

When you take the liquid crayons out of the oven DO NOT MOVE them around them too much.  Gently remove them from the oven and sit them on the counter.  Do not move them again until they are completely cooled.  Too much jiggle while everything is liquid can muddle the colors.

    Saundra – good luck! Muffin tins come in all shapes and sizes so the fun ideas are endless. Also I saw a big bag of crayon bits at the thrift store yesterday so check there. I got mine at Big Lots.

    I'm trying to think of a way to use candy molds. They come in such cute shapes, but they are plastic so the oven idea is out. I wonder about some sort of make shift double broiler or

    We would just melt the crayons, on the stove, like in a pie pan, lol,

    If you use the candy molds, you may have to melt your wax, set mold on top of ice/water mixture, and then pour into molds. Def check test by dropping a bit of the melted wax on a corner of the mold, both without the ice and one with the ice to see if it melts it.

    Do you have a candy thermometer? Use it to check the temperature of your melted crayon wax. Some of those candy molds can withstand pretty high heats – this site says that all of theirs have a max temperature range of 110-140 ( But if you have sugar molds, those can withstand really high heats, up around 300.
