Bg3 Melting Furnace Recipes and How to Use the Furnace for Crafting

The melting furnace in Baldur’s Gate 3 (BG3) converts ores, metal objects, and certain salvageable items into usable ingots and crafting components that power blacksmithing, weapon upgrades, and advanced crafting. This guide explains how the Melting Furnace works, common recipes and inputs, furnace locations, crafting workflows, and practical tips to maximize resources and crafting efficiency.

Item Input	Typical Output	Common Use
Iron Ore / Rusted Metal	Iron Ingot	Weapon/Armor Upgrades, Swords, Nails
Copper Ore	Copper Ingot	Basic Tools, Bronze Alloys
Silver Ore / Silver Trinkets	Silver Ingot	High-Value Trade, Jewelry
Gold Nuggets / Gold Jewelry	Gold Ingot	Economy, Special Accessories
Mixed Metal Items / Weapons	Refined Metal (varies)	Raw Material For Forging

What The Melting Furnace Does In BG3

The Melting Furnace is a crafting station that transforms metal-based inputs into purified ingots or refined metal components. These outputs are required for blacksmithing recipes at the forge or anvil and for modding and upgrading certain weapons and gear. The furnace simplifies inventory management by turning cluttered scrap and low-tier metal goods into widely usable crafting materials.

Key Function: Convert ores, rusty metal, and eligible metal items into ingots and crafting components for use with other crafting stations.

How To Use The Melting Furnace

Approach the furnace and interact with it to open the smelting interface. The UI typically shows available inputs on the left and predicted outputs on the right. Players place ore or metallic items into the input slots, confirm the smelt action, and collect the resulting ingots or refined materials when processing completes.

Steps: 1) Open furnace UI, 2) Insert ore or metal items, 3) Confirm smelt, 4) Retrieve ingots.

Common Melting Furnace Recipes

Recipes can vary by game version and installed patches. The following list reflects the common, broadly applicable conversions players expect when using a melting furnace in BG3-style crafting systems.

• Iron Ore / Rusted Metal → Iron Ingot: Iron is the core output for early- and mid-game weaponry and armor reinforcement.
• Copper Ore → Copper Ingot: Used alone for simple tools and combined with tin to make bronze when alloying is supported.
• Tin Ore + Copper Ingot → Bronze Ingot: If alloying rules are implemented, bronze is useful for certain low-tier crafted items.
• Silver Ore / Silver Trinkets → Silver Ingot: High-value metal for trade and crafting specialized jewelry or components.
• Gold Nuggets / Gold Jewelry → Gold Ingot: Primarily for currency, trade, or special high-end craft recipes.
• Mixed Metal Weapons/Armor → Refined Metal Scrap: Breaking down unwanted metal gear often yields variable refined metal used as crafting currency.
• Rare/Exotic Materials → Specialized Ingots: Rare materials (e.g., mithral-like ore) often produce unique ingots for advanced forging—availability and recipes depend on game updates.

Where To Find Melting Furnaces And Ores

Melting furnaces are commonly found in industrial or mining locations such as mines, forge complexes, traders who handle metalworks, and certain camps. Ores and metal scrap are discovered in mines, ruins, patrols, merchant inventories, and by looting fallen foes.

Search Tips: Inspect mining tunnels, blacksmith workshops, and trade caravans. Loot chests and trade with merchants to obtain ores, trinkets, and metal items suitable for smelting.

Which Items Can And Cannot Be Melted

Metal-based items, ores, jewelry, and many weapons and armor pieces are eligible for smelting. Organic materials (leather, cloth), gems, and magical artifacts may not be meltable or may have special outcomes.

Non-Meltable Items: Enchanted artifacts often resist smelting or destroy enchantments and should be handled cautiously. Gems usually require separate crafting processes and do not become ingots.

Managing Enchanted Or Unique Items

Enchantments complicate smelting. Melting an enchanted weapon commonly destroys magical properties and yields base materials only. In many cases, keeping unique or enchanted gear intact and using repair or disenchantment methods available in-game is preferable.

Recommendation: Avoid smelting unique or strongly enchanted items unless the player explicitly wants to reclaim base materials and accepts losing magical effects.

Practical Crafting Workflows With The Furnace

Efficient crafting uses the furnace as part of a multi-step pipeline: gather ores and scrap, smelt into ingots, transport ingots to an anvil or forge, and combine ingots with other components to create or upgrade equipment.

• Batch smelt to free inventory space and convert low-value trash into useful materials.
• Stockpile ingots for late-game upgrades—many high-end recipes require multiple ingots.
• Use merchant services to sell surplus ingots or trade for rare components.

Maximizing Resource Efficiency

Smart players minimize waste by optimizing what to melt and what to keep. Prioritize smelting low-value metal goods and duplicate items. Keep at least one copy of unique or rare weapons to avoid losing valuable mods or narrative items.

Tip: Combine merchant sales, smelting, and targeted looting to maintain a steady supply of ingots without overcommitting to farming runs.

Using Smelted Materials For Upgrades And Mods

Ingots and refined metals from the melting furnace feed directly into crafting recipes at the forge and anvil. They are commonly required for weapon upgrades, armor reinforcement, and crafting new weapon types or specialty components.

Examples: Iron ingots may be required for blade repairs; silver ingots for jewelry sockets or trade; rare ingots for late-game empowered gear.

Common Player Questions And Troubleshooting

Players often ask whether items always yield the same output, whether enchanted items can be safely smelted, and where furnaces are located. Outputs can vary by input type and game patch; enchanted items typically lose magic when smelted, and furnaces are placed in industrial or smithing areas.

Fixes: If a desired output is missing, double-check the input type. Update the game to the latest patch to reflect current recipes and mechanics. Avoid smelting quest-critical items.

How Game Updates And Mods Affect Recipes

Patches and community mods may add new ores, change conversion ratios, or introduce new alloying mechanics. Players should review patch notes and mod descriptions to stay current with the melting furnace behavior and available recipes.

Action: Refer to official patch notes, community wikis, and mod documentation before assuming static recipes across play sessions.

Advanced Techniques And Alloying

Some crafting systems allow combining multiple ingots to produce alloys (for example, copper + tin → bronze). If BG3 implements alloying, players should experiment with different metal ratios and consult in-game recipes or the crafting UI for valid combinations.

Strategy: Keep a small variety of ingots to enable alloy experiments; alloy materials sometimes unlock superior weapon and armor tiers.

Economic Considerations: Selling Vs. Smelting

Deciding whether to sell metal items as-is or smelt them depends on current market prices, inventory needs, and available crafting recipes. Selling low-value items may be more profitable early on, while smelting becomes more valuable as advanced recipes demand ingots.

Advice: Track merchant prices for raw items and ingots. If ingots are frequently required for upgrades, prioritize smelting and stockpiling rather than immediate sale.

Where To Learn More And Keep Updated

For precise, version-specific melting furnace recipes consult the official Baldur’s Gate 3 patch notes, the BG3 in-game crafting tooltips, and active community resources like wikis and forums. These sources reflect live changes and community-discovered recipes that may not appear in base guides.

Official BG3 Site and community wikis are excellent starting points for the most current recipe lists and furnace locations.

Quick Reference: Smelting Best Practices

• Always inspect item descriptions before smelting; unique items may be non-refundable.
• Batch-smelt low-value metal goods to save inventory space and convert trash into useful ingots.
• Keep a supply of common ingots (iron, copper, silver) for crafting flexibility.
• Monitor game updates and community resources for new recipes and furnace changes.
