Large Furnace

The Large Furnace is a vital item in Rust, designed specifically for the efficient smelting of bulk quantities of ores. It outperforms the regular furnace in both capacity and speed. The types of ore that can be processed include Metal Ore, Sulfur Ore, and High Quality Metal Ore. As a fuel source, wood is essential, and this furnace can accommodate 2 stacks or up to 2000 wood units, sustaining a lengthy smelting operation.

When it comes to loading raw materials, the Large Furnace features 5 slots, allowing a maximum of 5000 ores to be smelted in a single batch. Finished products and by-products, such as charcoal, are collected in the 5 output slots. Placement of the Large Furnace requires careful consideration as it needs to be on terrain and occupies the space equivalent to 4 square foundations.

One crucial detail to remember is that the Large Furnace cannot be placed on constructed foundations or floors. Planning for its location is important in any base design. Utilizing the Large Furnace can significantly boost your resource processing, making it a game-changer for crafting and base building.
