Coal is for chumps!
When placed, a redstone furnace faces the player. It can face any of the four cardinal directions, and can be rotated using a wrench.
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.
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.
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. For fluids, auto-output also occurs every 4 ticks (0.2 seconds).
A basic redstone furnace can automatically transfer up to 16 items and up to 1,000 mB of fluid at a time. 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.
A redstone furnace may be configured to respond to redstone signals. It can be in one of three modes:
The current mode can be set using the Redstone Control tab in the machine’s GUI.
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.
When a redstone furnace is active, it emits a light level of 14.
Redstone furnaces come in five tiers.
|Tier||Max. power usage||Augment slots||Max. items per auto-transfer||Max. fluid per auto-transfer|
|Basic||20 RF/t||0||16||1,000 mB|
|Hardened||30 RF/t||1||16||1,000 mB|
|Reinforced||40 RF/t||2||28||3,000 mB|
|Signalum||50 RF/t||3||44||6,000 mB|
|Resonant||60 RF/t||4||64||10,000 mB|
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.
|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||Redstone Furnace||A specialization that increases 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||Redstone Furnace||A specialization that allows for a redstone furnace to process ores more efficiently. However, a redstone furnace can only process ores when installed.|
|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 2,000 RF.
Redstone furnaces have some recipes of their own, some of which replace regular smelting recipes. The following table lists these recipes.
|Result(s)||Ingredients||Energy||Redstone Furnace recipe|
|Metal Ingot||Smeltable Metal Dust||1,500 RF|
|Cooked Food||Raw Food||1,000 RF|
|Cactus Green||Cactus||1,000 RF|
|Lapis Lazuli||Lapis Lazuli Ore||2,000 RF|
|Redstone||Redstone Ore||2,000 RF|
|Leather||Rotten Flesh||4,000 RF|
