Feast your eyes on this unhinged crafting recipe lads. Cobble with a tiny bit of lava and some cinder flour makes netherrack, makes sense right? Well how do you get cinder flour? ... by crushing netherrack. You get 1.5 cinder flour per netherrack, which you can craft back into 1 block. So I guess you're taking a feedstock of netherrack and diluting it to a tiny ((aroma)) to wash the cobble blocks with.

Normally this would be pretty much useless since this block is so easy (and satisfying) to gather. However, on PathSerb the Nether Brick and particularly the Red Nether Brick have really nice textures so it's worth collecting a ton of netherrack to smelt up. There's already a brick factory on the serb, I guess I'm setting up a nether brick factory.
