Melted Crayon Art (and Why a Warming Tray ROCKS for This Art Activity)


Melted crayon art is one of our favorite kids art activities, but we weren’t doing it right until now. A thrift-store warming tray makes all the difference!

We’ve been big fans of melted crayon art forever.

We’ve been using this art technique ever since I first came across the idea in one of MaryAnn Kohl’s books.

What we were not using was the right tools.

The instructions called for a warming tray which I did not have, didn’t see at the store, and couldn’t find secondhand (I may not have tried hard enough).

And so we ad libbed with the “cookie sheet method,” which actually worked quite well. If you don’t have access to a warming tray, I recommend you try melted crayon art on a cookie sheet.

The cookie sheet method for melted crayon art


I came across a vintage warming tray at Goodwill recently and knew it was time to revisit melted crayon art the “proper” way.

We liked melted crayon drawings before.

But now? We’re obsessed.

Daphne hasn’t stopped making them.

Our studio windows are covered in their colorful stained glass magnificence.

And she’s even been writing notes and letters using the warming tray.

The nice thing about the warming tray is that it’s consistent, safe, and effective.

Melted Crayon Art - Using a Warming Tray

You can work safely for hours if you wanted to, creating melted crayon drawing after melted crayon drawing.

  • No need to reheat the cookie sheet every few minutes.
  • No need to keep an oven on.
  • And no need to protect the table with towels or the child’s hand with pot holders.

I like the warming tray method so much that I wish I had tried harder to find one before. I bought mine secondhand, but you can also get them new.

Here’s a video I created showing melted crayon art in action…

And here are the step-by step-instructions and photos…

You can do melted crayon drawings on a hot cookie sheet, too, as I mentioned earlier, but a warming tray is easier and more effective.

Melted Crayon Art with a Warming Tray - Materials Needed


*I bought my warming tray at a thrift store, but you can also get them new. I’ve seen them at places like Target and online on Amazon.


Melted Crayon Art with a Warming Tray - Setting Up

Step 1 :: Set Up

  • To set up for melted crayon art, you’ll want to cover your warming tray with the foil. (I used an 18 inch wide roll of Heavy Duty Reynolds Wrap, but I think any aluminum foil would work fine.This will protect the warming tray and also make clean up easy. I wrapped my foil around to the back and added a little tape to help hold it, but I think it would stay in place fine without.
  • Plug your warming tray in and turn the heat to low or medium.
  • Set a sheet of paper on the surface.
  • Have your crayons nearby and ready to use.

Step 2 :: Draw on warm paper + tray.

Use your crayons to draw on the warm paper and tray. The crayon will melt as you draw, creating a paint-like effect of vibrant color.

Continue to draw until you are finished with your artwork.

My kids made some melted crayon artworks that completely covered with the colorful melted crayon. And they made some that still had plenty of white paper showing.

Step 3 :: Remove Melted Crayon Artwork from Tray

When the artwork is deemed complete, remove it from the tray.

Step 4 :: Make Another!

Lay another sheet of paper on the tray and continue to make melted crayon art as long as you like! As I said earlier, Daphne kept at this for hours and days.

Step 5 :: Display in the Window

You can display your melted crayon drawings anywhere, but they have a wonderful stained glass effect with light shining through them. I taped ours to our studio window.

You can see Daphne’s swirly Sky with Clouds artwork above as well as a close-up detail of it back lit in the window.


How about you? Have you tried melted crayon art with your kids? Or did you do this as a child yourself?

Remember, you can do this with a cookie sheet. But I do recommend keeping an eye out for a warming tray, if you don’t already have one. The warming tray takes this technique to a whole new level and make it much easier and more effective!

    Have you ever tried this with an electric griddle? I wonder if it has a low enough setting for it to be effective. Warming trays are expensive and I don’t have time to shop at second hand stores regularly enough to find one.

      I haven’t tried it with an electric griddle, but if you have one, why don’t you give it a try on the lowest setting? And then check back here and leave a comment so the rest of us know! Thanks, Kristen!

        Great! Give it a try and let us know, Michelle! I imagine if there’s a relatively low setting on the griddle, it should be totally fine. :)

      We use a cast iron griddle on our gas stove set to the lowest setting. It’s still a burn risk, so it’s got to be supervised very carefully, but we don’t use pot holders or anything.

      Also, glitter crayons are amazing for this project.

      I think that would always be too hot. Warming trays are not for cooking. Griddles are.

      Also, warming trays’ top layer is glass, a griddle is metal. I suspect you may have a problem with things sticking to a griddle that don’t on a warming tray.

      Just my thoughts after using warming trays for crayon melting with kids for well over 25 years.

      P.S. Never ever buy a NEW warming tray for crayon melting! They are AAAAAAAALL over eBay for under $10! I just saw one for $1.99!

    Oh my – I LOVE Sky With Clouds, and the huge flower too! I had sworn off crayon melting following a disastrous project using a hairdryer. Daphne’s work has inspired me to try again if I can find something to use.

      Oh! That’s so funny, Abi! I had forgotten about melted crayon art with hairdryers.

      Yes, definitely give this one a try. Even if you just use the cookie sheet method!

    Jean! Amazing as usual! And thanks to you melted crayon posts of the past, we found a warming tray ourselves at local second hand store, $5! Also we bought copy of Mary Art book as well! One of the best kids art books we have purchased. Thank you for sharing so much great stuff with us!!

    I wonder if a heating pad under a cookie tray would work? This looks cool but I don’t want to buy more clutter!

      Maybe. I’m not sure, Lindsey. You could give it a try and let us know. :)

      The cookie sheet method of putting it in the oven and working on the hot cookie sheet *does* work, even if it is a bit less convenient. So you could always do that if the heating pad doesn’t.

      Also, if you find a warming tray at the thrift store, you could pick it up for a couple weeks of melted crayon art and then pass it on to a friend, give it to a preschool, or donate it back to the thrift store. To give the activity a try and avoid the clutter issue. :)

    Would this work directly onto wax paper for a better stained glass effect, or would the paper melt?

      The stained glass effect is pretty remarkable on regular paper, Jane! I’d worry about all the wax on the wax paper melting off and causing a problem, but if you give it a try, let us know how it goes!

    How hot does a warming tray get? Seems like little ones could get easily burned. And it’d be difficult to keep them from touching the surface. Sounds risky.

      You can adjust the heat on ours and it didn’t seem to get too hot even when cranked up. I don’t have experience with other warming trays, though, so I guess just use your best judgement. I’ve always had talks with my kids about safety when using heat in art and in cooking and have never had a problem. Sometimes in the past they would use a mitten type potholder on the non-drawing hand.

    Good news: I found a warming tray at a garage sale this summer!!! Bad news: I haven’t brought it into class yet because I have yet to figure out the logistics of 1 warming tray + 18 kids with only 1 hour MWF to let them color at their pace. So, still on the lookout for another 1 or 2 trays. I’ve tried it and it is awesome!!

      Good news, indeed! Perhaps have a side table with 1 or 2 warming trays for kids to come work on in between other projects?

    I’ve been doing this since 2001 on the same warming tray. It just gave up but I have a new one standing by. Be aware that the quality of the crayons makes a big difference. I tried a couple of house brands instead of Crayola and the colors just weren’t intense enough. I like the technique of having the kids draw on foil and then take a “print” with a piece of white cotton. Old sheets work well! You get a batik effect. There’s often enough color left on the foil that you can display it next to the cotton print.

      Thanks for sharing! We did prints on paper, but not on cotton. I’ll definitely give that a try next time we get the warming tray out. Thank you!
