Crafting[edit | edit source]

The lit furnace block cannot be obtained, even with commands. In Pocket Edition however, the lit furnace block can be obtained by inventory editing, as well as using a Silk Touch pickaxe. This allows lit furnaces to be obtainable in Survival. It will always stay lit, despite no items being inside of it.

Usage[edit | edit source]

Furnaces cannot be pushed by pistons.[Computer and Console editions]
