Furnace

The furnace in Rust is a fundamental crafting item used for the essential process of smelting metal ore, sulfur ore, and high quality metal ore. It is known for being the most cost-effective solution for players looking to convert their raw materials into usable bars. Upon placing ore and wood as fuel inside, the furnace will begin to heat and produce metal fragments, sulfur, or high quality metal, depending on the ore used.

Crafting a furnace requires low-grade fuel, stones, and wood, materials that are relatively easy for players to gather early in the game. Its accessibility makes it an indispensable item for progressing in Rust, allowing players to craft stronger tools, weapons, and armor with the processed materials. Moreover, the furnace has to be used strategically, as it emits smoke and light that could attract unwanted attention from nearby players.

To maximize efficiency when smelting, it's recommended to distribute your ores and wood evenly across the furnace's slots, ensuring a steady production of materials. Experienced players often use multiple furnaces simultaneously to expedite the production process, which is crucial during the crafting of more advanced items that require large quantities of smelted materials. In essence, mastering the usage of the furnace is a key step towards becoming an advanced Rust player.
