this is the mysterious crayon project!using old crayons…i made new ones. i bought these silicon letter trays.(you can make ice or bake in them too.) first break the crayons up and put the pieces into the shapes on the trays.set the silicone trays on a cookie sheet for stability.preheat your oven to 250-ish.put sheet of trays into the warm oven and check at 10 minutes.when all the crayons pieces have become liquid….they are done!remove the sheet from the oven and let cool for at least an hour…or 3 or 4. the liquid wax was beautiful! it was such bright colors.i was loving it!i wanted to pour it all over something and paint with it.maybe another time….
