Blaze Rod

Blaze Rods are items which are dropped by Blazes, mobs which are found in or near Nether Fortresses and which appear to have these rods as body parts. They are essential for brewing potions, and are commonly used for locating Strongholds.

Obtaining
When killed by a player or tamed wolf, a Blaze may drop a Blaze Rod. Blazes which are killed by other causes will not drop any Blaze Rods, making fully automated farms almost impossible. The mechanic here is the same as for Experience, i.e. the player does need to deliver the final blow.

As a fuel
When used in a Furnace, a Blaze Rod lasts 120 seconds (12 operations), which is third only to Coal Blocks and Lava. This makes Blaze Rods one of the most effective renewable fuels.

Trivia

 * The Blaze Rod texture appears to be derived from the stick texture.
