This is my first PMC COMPLETE submission!

This is a simple redstone contraption that cooks materials by putting them in chests. It could be useful. If you have a whole bunch of one item, or a whole bunch of fuel and you need to cook it, then you can. And easily too.
I included a schematic, and a world save. If you use this on a server, Please give me credit. IDC if you try to copy it though. The only unique aspects of it, is the architecture.
I hope you enjoy!
