I used a new (no rust, scratches, dents, wear, etc) non-stick muffin tin (not
teflon or anything fancy like that, just those shiny new pans you find in
KMart etc.) I broke up the peeled crayons just enough to fit into the tin,
and only put related colors in any one spot. Heap them up, because they mush
down as they melt and come out sort of like a hockey puck.
Put them in the oven at about 200 degrees and keep an eye on them. You want
them to get just barely fused together. If they get too hot the pigment and
waxes get separated and they do not work nearly as well. I found the about
twenty to thirty minutes worked pretty well, but it will depend on your oven.
Check them frequently!
As soon as they were melded together, I took them out of the oven and set
them out to cool. When the pan is cool enough to handle, just invert and pop
them out. Then let them finish cooling. If you have trouble getting them to
pop out, just let them cool a little more, they should release easily.
These are great to use for rubbings. I had the students draw simple designs
on corrugated cardboard with thick lines of glue. Let the glue dry
completely, then use to make rubbings. Great for Christmas gift-wrap for
instance. The children can swap glue designs and have an assortment of
designs on one large paper. Ask your local newspaper for roll ends. (Note:
if you do glue designs on thinner cardboard, the moisture in the glue will
warp the cardboard. It will curl up and the glue will run and spoil your
The above was a wonderful project for my profoundly handicapped students.
They could actually hold the hockey puck shape of the crayons, and rub!
