Laura over at My Montessori Journey sent me an e-mail wondering if the Letter Ice silicone molds would work for making crayons. I had been meaning to try this, so Natalie and I did a test run this afternoon.
I peeled the paper off the crayons, and Natalie broke them into small pieces. We filled each letter with one or two colors – each letter used 2-3 regular size crayons. By the way, use regular crayons, not washable, or you will end up with a layer of clear wax on the top of your crayon.
Put the molds on a cookie sheet and then into the oven. I set my oven at 275° and it took around 20 minutes for the crayons to melt completely. Remove from the oven to cool. Or, if you are making multi-color crayons, just turn off the oven and let the crayons cool inside. If you move them, the melted wax moves around and the crayons sometimes come out looking brown, not swirled with colors.
Once mine were somewhat solid, I put them in the freezer to speed up the cooling process (because I am impatient!). However, I did break a few when I removed them from the molds (H, N, S, U and W). This is probably because they were a bit brittle from the freezer. And maybe I wasn’t taking my time, like I should have. :) There is no sticking, though, and they come out easily.
Laura mentioned these would make great birthday gifts, spelling out the birthday child’s name. I think I will also make a set to donate to the girls’ preschool and kindergarten classrooms for their art centers.
