At this point I realized I had no idea how long or at what temperature to bake the crayons. I did a quick google search and came across dozens of different ways. I decided to go with Close To Homes directions and ended up changing them just a bit.

Preheat your oven to 225. Remove all the crayon wrappers and discard. Break the crayons into small pieces and place them in the tray. You can sort them by color like we did or just pile them in there and see what you end up with.
Place the trays on a cookie sheet for stability and place them in the oven. Bake until all the crayons are melted. We started with 5 minutes but ended up baking them for almost 15. The time really depends on how thick you layer your crayons - ours were pretty thick.
Once the the crayons are all melted removed the trays and place them in the freezer. I cleared off the top shelf of mine and just stuck the entire cookie sheet in. Let the cook in the freezer for about 15 minutes. Now you can pop out your beautiful heart crayons and start coloring. My girls spent the entire evening making valentines with their crayons!
