hot rocks! painting with wax on rocks

My little ladies love melting crayons on hot rocks on a cold and chilly Ohio day!


smooth rocks
cookie sheet
crayons (wrappers peeled off)
hot pad holders
a heat resistant cover for the table

1. Gather the smoothest rocks you can find and give them a good bath.
2. Put clean rocks on the cookie sheet and put in a 350 degree oven for 15 minutes. I’ve seen people put aluminum foil on the bottom of the cookie sheet, but this isn’t really necessary.

3. Peel crayons while you wait for the rocks to get hot.
4. Using a hot pad holder- CAREFULLY (HOT), place the rock on a heat resistant surface. Note- wax paper wasn’t the best choice for this project, I’m still scraping wax off the counter. Not sure where my head was!

5. Start melting the crayons on the rocks. It’s so pretty to watch the wax melt all over the rock. It’s more like painting with wax than coloring.

6. I kept the rocks waiting to be “painted” in the hot oven to keep them hot while the girls worked on individual ones.

Warning- Fauna  and Araina found themselves burning their fingers more from the hot wax than the actual hot rock itself.

*I have actually braved this activity with a preschool class of 5 year olds years ago, I don’t plan on ever doing that again.  I would stick with the 7 year olds and up. ;)

“That’s all,”

    Oh I just LOVE this idea! Thank you for sharing it! We’re coming up to winter on our side of the world, and this will be a brilliant activity for me and the kids to get in to. I’ve got a stash of crayons which I’d put away because they were a bit too hard to draw with when the kids were little, and they will be perfect for this craft. Hooray! Thanks again.

    Hello from another Ohio blogger. My kids love to do this to and we also like to color our Easter eggs this way. I love the lizard looking rock. We normally just have smudges and blobs oozed together on ours. Have a great week and keep warm.

    Hi Again!

    I did this fun little activity with the little guy I nanny for, and we had a great time! I posted about it today here:

    Thanks again for the idea!

    This is a great idea!!!!! I’m totally going to do this with my little charge tomorrow! Thanks for the idea :)

    what a fantastic fun idea!

    Wow! This is really cool. So easy, with things i already hace in the house (…and Yes, i have lots of rocks in my house)

    You are full of great ideas, Lisa. Thanks for always sharing them.

    That looks like so much fun! I want to do this! I’ll be linking as well.

    This is so cool. We’re heading up to the cabin for spring break and this will most definately be one of our crafts.

    So, where did you get the rocks from Lisa?

    what a grand idea! we had all sorts of fun last week with an old thrifted hot plate (remember those trays, for buffets?!), paper, and old crayons — the heat transfers through the paper, and the crayons melt on impact. Washed out old crayons suddenly get jolted into majestic brightness. And yes, it is more like painting.

    I’m thinking pet rocks may be in our future…

    ooh, wonderful idea!
    hot stones is brilliant.
    Madd would love this!

    Well we’ve painted stones and melted crayons, but never combined the two. I have the perfect stones at hand and a basket of crayons. Now all I need is a rainy day. Just not too soon, please! Thanks for the inspiration.

    What a fun idea! I have to try this with my daughter. She’s five so I will take your advice and work with her on this rather than let her be. And, the stones – they are hard to find here in Delhi, for creeks are an alien sight here :(

    What a fun idea! We’ll have to do this tomorrow, the girls have their cousin over spending the night, so it will be perfect on this rainy weekend. Thanks!

    I was going to ask where we can find smooth rocks… but I see. The creek. :)

    looks like so much fun. We’ll have to try it.

  • March 4, 2011 - 6:25 pm | Permalink

    oh I LOVE this project! Now we’ll have to find a creek for some of these smooth rocks. Most the ones around here aren’t smooth–maybe it’d still work?

    • March 4, 2011 - 9:43 pm | Permalink

      It works on all textures of rocks, but the smooth ones are the very best. It would be very worthwhile to visit the creek for some. ;)

    What a fun idea! Afterward the girls should give mom a hot stone massage.

    what a fun project! i love how they turned out!
    have a great weekend

  • March 4, 2011 - 4:44 pm | Permalink

    Wow. This is cool. We’re doing it!

  • March 4, 2011 - 4:39 pm | Permalink

    I’ve always loved the idea of this craft. It’s a shame that we don’t have nice rocks around here. Just sandstone and limestone. :/
