A furnace (also known as a smelter) is a block used to heat and convert items into another form, usually being ores or meat. A furnace (similar to a crafting table) is considered one of the fundamental blocks required to advance in survival mode.

Obtaining

8 pieces of cobblestone are required to craft a furnace. The crafting design should be a square with the center blank.

Cobblestone Cobblestone Cobblestone Cobblestone Invisible-sprite Cobblestone Cobblestone Cobblestone Cobblestone Furnace

Usage

The furnace can be walked through and does not count as a barrier for the player and other entities. However, it does not get destroyed by water and can be pushed by a piston like a normal block. redstone, signs, and any torch can be placed on it like a regular block.

Shift-click (or right click) to open the furnace menu.

  • Top left: items to be smelted. (input)
  • Bottom left: items to be burnt as fuel.
  • Right: items produced. (output)
  • Left indicator: Remaining heat, as a proportion of total heat given by last fuel item consumed.
  • Middle indicator: Per-item smelting progress.

Process

Smelting begins only when both left slots contain items, or input items are added while there is residual heat available.

  1. One fuel item is removed and converted to heat. Note: Heat is depleted at a constant rate, regardless of use.
  2. Smelt indicator progresses. Note: All smelts have the same heat cost.
    1. IF heat runs out before a smelt completes, then more fuel is burnt (1) if available, otherwise the smelt fails. Note: adding fuel afterwards resets progress rather than adding to it.
  3. Upon smelt completion, IF there is output space, one input item is removed, and one output item added. Note: If there is no output space, the input item remains, and fuel is continuously consumed.
    1. IF input items remain, continue from (2).
  4. Once no input items remain, no further fuel is consumed. Any remaining heat will steadily deplete regardless with some waste likely before additional input items can be added to use it.
