Lego Minifig Crayons. // My suggestions: melt at 190-200* F (much higher and you get waxy separation really easily). Use smaller cans - like for canned veggies, rather than coffee-size (makes pouring into molds easier). After pouring into molds allow to sit 15 min, then place in freezer for 15-20 min. If making multiple colors, use one mold for the same color until finished - if you don't get all the residue out, your crayons will be mixed colors.
