Easy Kid Craft–Hot Rock Painting

My kids are collectors . . . . which explains this . . . .
Rock Collection
. . . . their rock collections.

Since it’s summer break and they’re begging for crafts we decided to try hot rock painting.
 Super easy.  Heat some rocks in a 350 degree oven for 15 minutes.  Then “color” with crayons.  The crayons actually melt really quickly on the rocks so it’s more like painting.

What we learned:
     * The rocks are hot . . . . . REALLY HOT!  This is the reason for the oven mitt you
         see in the picture on the left.  Even though it looks like it’s just laying there it’s
         really on my daughters left hand.  She used it to hold and move the rock. 
     *  The wet wax is like paint and if you touch it with the oven mitt it will transfer . . . .
         easily.  You can see the smudges on the fingers of the mitt in the photo.  Hopefully
         it will wash out.
     *  I would recommend putting the rock that's being colored on a paper towel or
          newspaper.  The wax runs.  I had to scrub the crayon off my cookie sheet (although
          it wasn't that hard to clean up)
     *  To keep the rocks hot without having to leave the oven on we just removed one at
          a time to color and left the rest in the warm oven after it was turned off.  Each kid
          was able to color 5 rocks and they were still plenty hot. 
     *  The colors will run.  Less is better.  When my kids tried to color too much they started
          to run together.  Needless to say we have a few rocks that are just swirled colors.
          Still pretty but not the original plan.
     *  Smooth rocks work best for drawing a picture, rough rocks still work but are easier to
          just scribble on.

Overall this was a great craft and my kids loved it.  They plan on collecting a more rocks that are smooth to try again soon.  I was worried about the hot rocks and burns but my youngest, who just turned 5, was able to participate with no problem.

  1. That sounds fun! I was thinking about painting rocks but this sounds even easier. Maybe I won't heat them so long since mine is only 4 years old and not coordinated to stop touching it :)

    1. You could definitely heat them for less time. The crayons melt very easily. My kids did forget and touch them a couple of times but they had slightly cooled at that point and it didn't hurt them.
