Homemade Rainbow Crayons

With Miss Kaboodle finishing playgroup and the summer holidays starting, we’ve been trying our hand at some more home made crafts.

Recently, following a huge clear up of the toy boxes around the house, I found myself in possession of a big pile of broken crayons. Instead of throwing them out I decided we would melt them down into new crayons.

These were so super easy to make and they turned out so well that I’ve even considered buying more crayons just to break up and melt!

What you’re going to need;

  • crayons
  • an oven proof silicone tray (one you don’t want to use for anything else.)
  • a baking tray

What you need to do;


  • Make sure none of the crayons have any paper left on them.
  • preheat oven to high temperature, we used gas mark 7.
  • Break up the crayons into small pieces.
  • Put a mixture of the smaller pieces of crayon into the silicone tray covering the bottom (not sticking out like they are in one of my photos haha!)
  • place the silicone tray onto a baking tray.
  • Put the baking tray on the middle shelf of the oven and leave them in there for 5 minutes.

It will get a little stinky but nothing too major, I just kept willow out of the kitchen while they were being melted.

Once the 5 minutes are up, carefully remove the tray from the oven. The crayons will be liquefied and extremely hot, I also kept Willow out of the kitchen for this part.

Leaving the silicone tray on the baking tray, put them on the side, out of reach and leave them to cool for 20 – 30 minutes. You want to wait until they’re completely cool before removing them from the silicone to avoid misshaping them or breaking them.

As soon as they have cooled down enough to remove from the silicone tray, they’ll be cool enough to colour with!

Miss Kaboodle had a ball playing around with her new crayons and I will say, I did too! They were awesome, we just kept drawing squiggly lines and seeing how the colours turned out. They were amazing to play with and what’s more, because of their new shape, they’re easier to store and use again and again. The amount of times I have stumbled across a broken bit of crayon while I sweep or hoover is uncountable and having such a great way to use them all up is fab! I’m happy, the child is happy! Win-Win!

As always, thanks for reading! If you ever melt your old crayons (or go out and buy new crayons just to melt) share a link with us! We’d love to see your creations!

    You could try silicon chocolate moulds as well – they are smaller than traditional cupcake moulds and come in all sorts of designs…Christmas, dinosaurs, flowers… xx

      Thanks! Yeah, so long as the silicone moulds are oven proof, any shape could be used! I tried to make penguins shaped ones before and ended up melting the tray because it wasn’t oven proof!
