Redstone Furnace (Thermal Expansion 5)

The Redstone Furnace is a machine added by Thermal Expansion 5. It functions identically to a Furnace, but consumes Redstone Flux (RF) instead of burning solid fuels like Coal. It smelts items such as foods and dusts faster than a vanilla Furnace. Each face can be configured to automatically input and output items to tubes or adjacent inventories.

Uses
Most smelting recipes can be performed in the Redstone Furnace for 2000 RF. Smelting dusts uses 1500 RF, and cooking food or making Cactus Green uses only 1000 RF, making it more efficient to use a Redstone Furnace for these purposes. Additionally, the Redstone Furnace can be used for unique recipes:

Upgrading
A Redstone Furnace is crafted at the lowest tier (Basic). It can be upgraded to higher tiers using Upgrade Kits. As it is upgraded it is able to use more RF per tick, which allows it to process items faster. Upgrading also adds augment slots, and increases the input and output rate of items and fluids.
