Furnace

Quest: This ruins my aesthetics! ''The vanilla furnace recipe has been changed to instead give a slab furnace. They are functionally identical, but the slab furnace takes up only half a block. You can't put 2 in the same block, but you can make functional stairs out of it I guess.''

The vanilla furnace is made using 8 compressed cobble instead of 8 cobble.

The slab furnace requires 8 cobble, and the full furnace takes 72 cobblestone, crafted into 8 compressed cobblestone.

The slab furnace and furnace can be automated with hoppers early game. Once you build a blast furnace and can make steel, the Extra Utilities pipes with a couple of item transfer nodes can automate an array of furnaces. At this point, it is still cheaper to use hoppers under the furnaces, rather than item transfer nodes.
