Redstone Furnace

Redstone furnace

Coal is for chumps!

A redstone furnace is a machine that smelts items.


A placed redstone furnace can be instantly picked up by dismantling it with a crescent hammer. Its configuration is preserved in the item. It can also be mined using a pickaxe, though this can be much slower.



A redstone furnace is initially at the lowest tier (basic). It can be upgraded to higher tiers using upgrade kits and conversion kits.



When placed, a redstone furnace faces the player. It can face any of the four cardinal directions, and can be rotated using a crescent hammer or similar.


When items are placed in a redstone furnace’s input slot, the machine will start consuming Redstone Flux to process them. Every item requires a certain amount of energy to process. When enough energy has been consumed for an item, the input is consumed and the output is placed in the output slot.

When installed, pyrolytic conversion makes a redstone furnace produce creosote oil, which is placed in an added output tank.

The speed at which a redstone furnace processes items depends on how much energy it can use per tick. This in turn depends on how much power is being supplied, and on the machine’s maximum power usage. A basic redstone furnace has a maximum power usage of 20 RF/t. This can be increased by upgrading the machine to a higher tier, and by installing certain augments.

Input and output

Items and fluids can enter and exit a redstone furnace through its sides. Every side of a redstone furnace may correspond to its input slot, its output slot (and possibly its output tank), or both at the same time.

A redstone furnace can automatically transfer items or fluids out of any sides that directly correspond to its output slot/tank. This is called auto-output. It can also transfer items from adjacent inventories into any sides that directly correspond to its input slot. This is called auto-input. Auto-output and auto-input occur whenever the machine finishes processing an item, or every 32 ticks (1.6 seconds) if the machine is inactive. Auto-output for fluids occurs whenever there is a fluid in the output tank.

A basic redstone furnace can automatically transfer up to 8 items at a time, and can automatically output fluids at a maximum rate of 100 mB/t. These amounts can be increased by upgrading the machine to a higher tier.

Which sides correspond to which slots/tanks and whether auto-output and auto-input are enabled can be configured using the Configuration tab in the machine’s GUI.

Redstone control

A redstone furnace may be configured to respond to redstone signals. It can be in one of three modes:

Redstone control is disabled. The redstone furnace works whenever possible. This is the default mode.
The redstone furnace works when not powered. When powered, it stops working.
The redstone furnace only works when powered.

The current mode can be set using the Redstone Control tab in the machine’s GUI.

When a redstone furnace must stop working due to a redstone signal and is still processing an item, it will finish processing that item before stopping.


A redstone furnace can have a signalum security lock installed to restrict who can access it.


A redstone furnace’s configuration can be saved on a redprint to be copied to other redstone furnaces.

Light source

When a redstone furnace is active, it emits a light level of 14.


Redstone furnaces come in six tiers.

Tier Max. power usage Augment slots Max. items per auto-transfer Max. fluid auto-output rate
Basic 20 RF/t 0 8 100 mB/t
Hardened 30 RF/t 1 16 300 mB/t
Reinforced 40 RF/t 2 28 600 mB/t
Signalum 50 RF/t 3 44 1000 mB/t
Resonant / Creative 60 RF/t 4 64 1500 mB/t


A redstone furnace can have augments installed to improve certain properties or to change how it works. The amount of augments that can be installed depends on the machine’s tier. A basic redstone furnace cannot be augmented.

Augments can be installed in the Augmentation tab in a redstone furnace’s GUI.

Augment Installable in Description
Auxiliary Reception Coil Auxiliary Reception Coil Any machine Increases a machine's maximum power usage (speed). However, also increases the amount of energy required per operation. Can be installed multiple times.
Trivection Chamber Trivection Chamber Redstone Furnace A specialization that doubles the amount of cooked food a redstone furnace produces when processing raw food. However, a redstone furnace can only process food when installed.
Flux Anodizers Flux Anodizers Redstone Furnace A specialization that doubles the amount of ingots a redstone furnace produces when processing metal ores. However, a redstone furnace can only process metal ores when installed.
Pyrolytic Conversion Pyrolytic Conversion Redstone Furnace A specialization that allows for a redstone furnace to process various plant-based materials into charcoal, and coal into coal coke. It also produces creosote oil as a byproduct when installed. However, when installed, a redstone furnace can only process these items and its maximum power usage (speed) is reduced by a factor of 10.


Most smelting recipes can be performed in a redstone furnace for 2000 RF.

Redstone furnaces have some recipes of their own, some of which override regular smelting recipes. The following table lists these recipes.
