Nether Furnace

Nether Furnace is an un-released block, scheduled for Version 1.2.

Nether Furnace
The Nether Furnace acts like a normal furnace, except it is only used to smelt ores that come from the Nether.

It's crafted using Hellstone in the same crafting pattern as the normal furnace.

Trivia

 * A bug in the test version of 1.2 caused the furnace to turn back into a normal furnace when smelting started.
