In the automation sandbox developed by City From Naught, you do not lay down physical conveyor belts to feed your furnaces. Instead, mastering Brave New Wonders smelting requires coordinating a workforce of robotic automatons to transport raw minerals across post-apocalyptic terrain. Getting your early Brave New Wonders smelting infrastructure running smoothly on the Americas island ensures your fledgling outpost maintains a steady supply of basic construction parts and scientific data packs.
Every advanced production chain begins at the smelter. Whether you need metal plates to construct defensive turrets or refined crystals to manufacture computer logic, understanding how smelting works is essential for conquering the game's logistics puzzles.
Unlocking the Smelter and Laying the Groundwork
Your journey begins at the train station hub on the Americas floating island. You arrive as Pioneer Meera aboard a Monowheel, greeted by your mentor Corin. Before you can construct your first smelter, you must collect initial supplies from supply drop 986, which contains loose metal plates left behind from the old world.
Transfer the metal plates into your backpack by left-clicking or using shift-click to move the entire stack. Drive your Monowheel to the train station research hub and open the technology tree using the default shortcut key H. Deposit two metal plates to complete your initial research project: Monowheel Mining.
Unlocking Monowheel Mining grants two fundamental capabilities:
- The ability to manually mine resource nodes across the map by right-clicking on mineral deposits like coal, crystal shards, and metal ore.
- The blueprint recipe for the smelter, the cornerstone structure for converting raw ores into intermediate manufacturing goods.
When laying out your base, you do not need to worry about permanent mistakes. The construction system allows you to place blueprint sites even if you do not carry the required materials in your inventory. Once you gather the ingredients, pressing the G key instantly constructs any nearby structure. Furthermore, the game features a free relocate button, allowing you to move placed smelters across the terrain without material penalties.
Smelter Recipes and Production Ratios
The smelter functions as your primary thermal refining building throughout the early game. It handles raw inputs mined from sedimentary rock nodes and produces standard items used across manufacturing lines. Pressing the Alt key while hovering over a smelter opens its detailed status window, showing base recipe times and output rates per minute.
| Output Item | Input Material | Crafting Time | Production Rate | Downstream Usage |
|---|---|---|---|---|
| Metal Plate | 1 Metal Ore | 10 seconds | 6 per minute | Basic buildings, power poles, ammo, factories |
| Refined Crystal | 1 Crystal Shard | 10 seconds | 6 per minute | Crystal compounds, technology packs, power cells |
| Gunpowder | Coal | Variable | Batch processing | Dynamite crafting at the Weapon Factory |
Understanding throughput is critical for balancing supply lines. A standard smelter processing metal ore or crystal shards runs on a 10-second cycle, outputting 6 items per minute. However, the internal storage buffer of a smelter can only hold 10 completed items at a time. If completed plates or refined crystals sit uncollected, the smelter immediately enters a waiting for stock state and halts operation.
Mineral nodes on the map also affect input stability. Normal purity nodes yield standard mining speeds, whereas impure nodes operate at half efficiency, requiring twice as many mining automatons to feed a single smelter. Infinite pure nodes produce at 1.5 times standard speed, offering ideal long-term locations for permanent refining hubs.
Powering Your Brave New Wonders Smelting Grid
Smelters cannot run without an active electrical connection. Initial power generation relies entirely on Solar Power Collectors, which generate 4 megawatts of electricity each. You must construct power poles to route this energy from your collectors to your processing buildings.
Each power pole supports a maximum of six simultaneous line connections. When your base expands, track your electrical network status closely in the building inspector:
- Grid Output: Total electricity generated by active collectors and generators.
- Grid Demand: Total energy required by all connected active buildings.
- Building Demand: The individual power consumption of a selected machine.
If your grid demand exceeds total output, all connected structures experience severe operational slowdowns. Placing a Solar Power Collector near your initial metal and crystal nodes provides enough surplus power to run two early smelters and an Automaton Factory simultaneously. As your Brave New Wonders smelting grid scales up to support military production and compound crafting, you will need to add more solar collectors or transition to natural gas power plants unlocked in later tech tiers.
Automating Smelter Logistics Without Belts
Because the game lacks mechanical conveyor belts, all material transport relies on deployable automatons. You manufacture these units at the Automaton Factory by inserting Compute Cores recovered from old-world ruins and supply crates.
Early logistics setups utilize two distinct automaton roles:
- Miner Automatons: Assigned directly to a mineral deposit to extract raw ore or crystal shards and deposit them into a target inventory.
- Mover Automatons: Wheeled logistics units designed to haul finished products or raw items between containers and processing facilities.
A common beginner mistake is setting up two independent mover bots on simple loops—one hauling ore to the smelter, and another carrying finished plates to a storage warehouse. Because smelter crafts take 10 seconds, both movers spend excessive time sitting idle.
Players can solve this inefficiency by writing custom natural language commands in the behavior editor. By typing plain text prompts, the integrated command system compiles instructions into visual behavior graphs. For example, enter the prompt:
Deliver metal ore from [Ore Warehouse] to [Smelter], then deliver metal plate from [Smelter] to [Plate Warehouse].
This prompt programs a single mover to perform a two-way delivery cycle, completely eliminating bot downtime. Furthermore, community reports highlight the value of linking mover routines to colored status signals. You can configure a smelter to emit a red signal when its internal ore drops below 5 units, commanding your mover to restock only when materials run low. Intermediate storage warehouses holding up to 500 items should always be placed at the output end of your smelter lines to prevent buffer overflow.
Integrating Smelters into Advanced Production Chains
Efficient Brave New Wonders smelting forms the foundation for intermediate industrial tiers. Raw smelter outputs feed directly into the General Factory to produce Crystal Compounds. A single General Factory recipe consumes 1 Metal Plate and 1 Refined Crystal every 20 seconds, yielding 2 Crystal Compounds. Setting up two smelters—one dedicated to metal plates and one to refined crystals—provides the exact raw inputs needed to continuously supply two General Factories.
From there, downstream facilities utilize your smelted goods for research and expansion:
- Industry Research Packs: Manufactured in a General Factory using refined crystals and metal plates to unlock core tech tree milestones like Logistics 1, Energy 1, and Combat 1.
- Gunpowder and Weaponry: Smelters refine coal into gunpowder, which is routed into a Weapon Factory alongside thermal plates to craft dynamite.
- Terrain Clearing: Dynamite crafted from your smelter network clears fallen tree obstacles across the Americas map, granting direct access to large infinite resource veins.

Maintaining consistent Brave New Wonders smelting throughput ensures that downstream factories never starve for intermediate components as you prepare your base for continent-spanning airship expeditions.
Frequently Asked Questions
How do I unlock the smelter in Brave New Wonders?
To unlock the smelter, collect metal plates from the opening supply drop near your landing point, visit the train station hub, and select the Monowheel Mining technology in your tech tree (shortcut H). Depositing two metal plates completes the research, granting the smelter blueprint and allowing your pioneer to mine resource nodes manually.
Why does my smelter stop working even when connected to power?
A smelter usually halts for two reasons: a lack of incoming raw minerals or a backed-up output buffer. A smelter can only hold 10 processed items in its internal inventory. If an automaton does not remove completed metal plates or refined crystals, the machine pauses until space opens up. Ensure you have a mover automaton routing outputs to a nearby warehouse.
What is the most efficient mover setup for early Brave New Wonders smelting?
Player experience shows that using a two-way prompt in the behavior editor is far superior to using two separate movers. Instructing one mover automaton to carry raw ore to the smelter and return with finished plates to a storage warehouse cuts your required robot count in half while keeping delivery loops synchronized.
Can I relocate my smelter without losing construction materials?
Yes. Brave New Wonders features a dedicated relocate tool that allows you to pick up and reposition existing buildings instantly without spending additional resources or dismantling the structure.
