What’s the optimal amount of coal for smelting a full stack of black metal scrap?

In Valheim, smelting black metal scrap into black metal bars is a crucial step for crafting high-tier weapons and armor. To determine the optimal amount of coal needed for smelting a full stack of black metal scrap, you need to understand the game''s smelting mechanics and resource requirements. A full stack of black metal scrap consists of 50 pieces, and each piece requires 2 coal to smelt into a black metal bar. This means you will need 100 coal to process a full stack of black metal scrap.\n\nTo begin smelting, you must first build a Blast Furnace, which is unlocked after defeating Moder, the fourth boss in the game. The Blast Furnace is specifically designed for smelting black metal scrap and requires 20 fine wood, 10 iron, 5 surtling cores, and 20 stone to craft. Once constructed, place it in a secure location near your base, as it is essential for late-game crafting.\n\nCoal is a vital resource in Valheim and can be obtained in several ways. The most common method is by burning wood in a Charcoal Kiln, which converts 25 wood into 1 coal. Alternatively, coal can be found in chests within Burial Chambers or obtained by defeating Surtlings in the Ashlands biome. For efficient coal production, set up multiple Charcoal Kilns near a steady supply of wood, such as a dense forest biome.\n\nWhen smelting black metal scrap, ensure your Blast Furnace is fueled with enough coal to avoid interruptions. Each Blast Furnace can hold up to 20 coal at a time, so you will need to refill it periodically. To smelt a full stack of 50 black metal scrap, you will need to refill the furnace with coal at least five times, as each refill allows you to smelt 10 pieces of scrap.\n\nA common challenge players face is managing their coal supply while balancing other resource needs. To optimize your workflow, consider setting up a dedicated coal production area with multiple Charcoal Kilns and a nearby wood farm. This ensures a steady supply of coal for smelting and other crafting needs, such as forging iron or cooking food.\n\nFor new players, it is important to prioritize coal production early in the game, as it is used in various crafting recipes. Experienced Vikings can streamline the process by using portals to transport resources between biomes, such as bringing wood from the Meadows to the Ashlands for coal production. Additionally, consider using carts or boats to transport large quantities of resources efficiently.\n\nIn summary, smelting a full stack of 50 black metal scrap requires 100 coal, which can be obtained through Charcoal Kilns or by exploring dangerous biomes. Build a Blast Furnace, maintain a steady coal supply, and optimize your resource management to ensure smooth progression in Valheim. By following these steps, you can efficiently smelt black metal scrap and craft powerful gear for your Viking adventures.
