Creepy Crayons

I have been dying to try making recycled crayons for ages now, (It's one of the few things I've ever spotted on Pinterest that actually seemed 'doable') and when I spotted a brilliant silicone 'skull and bone' ice-cube tray in my local €2 shop I knew the time had come to give it a go.

I was actually shocked at how easy it was to make these and I love the look of the finished product. I also love how all of the cheapo, broken and stubby crayons my girls refused to use have been made desirable again.

You will Need:
Old broken crayons
A ‘skull and bone’ silicone mould  (find similar here)
An oven


  • Remove the paper from the crayons and break into small pieces
  • Fill the moulds to the top with the broken crayons
  • Set the oven to 140℃
  • Place the silicone mould on an oven tray, with some foil/greaseproof paper underneath it to protect from spills, and place in the oven
  • Keep an eye on it, but it shouldn’t take much more that 15 minutes for the crayons to melt completely*
  • Remove from the oven and place somewhere safe to let cool.
  • Wait until the wax has set and cooled completely before removing them carefully from the mould.

* Make sure the overhead fan is on and the room is well ventilated. Open a window at least!

These could be made in advance and used as a fun alternative to handing out sweets at the front door to trick or treaters, or just to have on hand for your own little monsters on Hallowe'en night.

They would also be cool as favours for a pirate themed birthday party!


  1. Oh, these are gorgeous! I'm a bit scarred thanks to a Pinterest idea where I cooked plastic beads to make sun catchers. We were poisoned: POISONED :-D I'll get some wax crayons for this!!

    1. Thanks! That's why I've been putting off trying them! I thought it would be seriously dangerous. So all of the crayons I used were labelled non-toxic and I opened the back door and a window just in case. In the end there were zero fumes and it was all fine!

  2. Oh these are fantastic, I must keep a look out for a mould like that

    1. Thanks Naomi! Any silicone mould would work, but I thought this one was pretty cool for Hallowe'en!

  3. I'm forever buying those novelty silicon trays and then not knowing what to do with them, I've ghosts from a few years ago so I'll try this out. Are they for decoration only or can you colour with them? Wouldn't they make really cool Christmas tree decorations too?

    1. Oh, ghosts would be fab! You can absolutely colour with them, they are basically smooshed up coloured crayons - in cool shapes! They would look lovely on an Xmas tree (well, maybe not the skulls exactly...) - pierce a hole in the top and string them up!

      P.S. I'd be VERY careful about cleaning the mould afterwards if you ever wanted to use it for foodstuffs. In fact, I don't think I, peronally, would use the mould for food at all after doing this, so just bear that in mind before you get started!


A penny for your thoughts?
