Blaze Rod

Blaze rods can be used as fuel, or for Blaze Powder, which can be used for brewing or Eye Of Ender.

Usage
This is used to cook 12 items in a furnace (with coal only doing 8). Blaze Rods can be cooked for the 2nd longest time(the first being lava, being able to cook a whopping 100 items).

You can craft Blaze Powder and Brewing Stands with it.

Picking up a Blaze Rod from the ground will give you the achievement "Into Fire" which gives you permission to earn "Local Brewery" and "The End?"
