Martha Stewart Kids, Volume 5 2002
Parents can use the knife to chop crayons into pea-size pieces, taking care to keep colors separate so kids can combine them as they like.
Preheat the oven to 150 degrees while children fill the tin with crayon pieces, arranging them in interesting designs.
Bake just until the waxes have melted, 15 to 20 minutes.
Remove the shapes after they have cooled. If they stick, place tray in the freezer for an hour, and the crayons will pop out.
Mini-cake tins (we used pans with heart- and circle-shaped pockets)
Heat makes a crayon a little loopy; it may melt into a swirl or pool into a whirl. With this in mind, we chopped up crayons and baked them in shaped mini cake tins, making large blocks that are easy for toddlers to hold and will surely inspire older artists. Encourage kids to come up with combinations: A blue-and-white blend for drawing the sky, for example, and a mix of reds and oranges for sunsets.
