As an artist I work in a lot of mediums, actually almost anything can be used to create art. During my search for suburban gold https://www.instructables.com/id/Mining-for-suburban-gold/ I often find crayons which until recently I would just throw out, then I remembered an instructable I had thought was pretty cool https://www.instructables.com/id/Melted-Crayon-Art/
While the one project uses several packs of crayons, I used 2 red, half a pink and only a little of 2 different orange and a white crayon on the one above

Step 1: The Test

I've only found a couple of crayons recently but it was enough to try my idea. I dropped a bunch of broken crayons on a piece of cabinet grade plywood scrap and hit them with a heat gun.

Step 2: What You Need

crayons, I ended up buying a couple of packs from the dollar store
heat gun or hair dryer
wood panel or stretched canvas
putty knife
needle nose pliers

Step 3: Create

The hardest part of this project is probably peeling the crayons! There is no right or wrong way to do this, my qst and second one I used broken pieces but half way through the 2nd one (yellow) I realized that if I held a whole crayon in the needle nose pliers and applied the heat I could get drips or lines on the 3rd (red) piece I grabbed a putty knife to help spread the wax to the edges. The 3rd and so far last piece I used full crayons, Sorry but the process doesn't really allow me to stop and take progress pics. From start to finish (other than peeling the crayons) none of these took more than 10minutes !

Step 4: Its ABSTRACT !

Because I allow the air from the heat gun to move the colors around I don't have much control over anything except the colors used, even the spots/dots/splashes are created by holding a crayon above and to the side of the surface and allow the force of the air to dictate where they land. I do try to add some lines but even those get moved by the hot air.

Abstracts can be a lot like Rorschach blots, different people see different things, my son see's a tree in the yellow one and he see's a dogs head in the red one. I guess it depends on what way you decide should be up
