Redstone Furnace

Coal is for chumps!

A redstone furnace is a machine that smelts items.

Obtaining

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

Crafting

Upgrading

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

Usage

Placement

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

Processing

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. 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.

Redstone control

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

Ignored

Redstone control is disabled. The redstone furnace works whenever possible. This is the default mode.

Low

The redstone furnace works when not powered. When powered, it stops working.

High

The redstone furnace only works when powered.

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

Security

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

Redprints

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.

Tiers

Redstone furnaces come in five tiers.

Augmentation

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	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.

Recipes

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.
