Refiner vs Forge: The Core Decision
One of the first and most important decisions you will make in Tectonic Industries is whether to prioritize building refiners or forges. Both are essential machines that increase your income, but they work in fundamentally different ways and serve different purposes in your mining operation. Building the wrong one first can slow your progression significantly, while making the right choice can accelerate your earnings from the very beginning.
This guide breaks down the differences between refiners and forges, explains when each one is the better investment, and provides a clear build priority guide for every stage of the game. By the end, you will know exactly which machine to build next at any point in your Tectonic Industries journey.

What Refiners Do
Refiners are processing machines that take raw ores and increase their value through various refining techniques. When an ore comes out of the mine and enters a refiner, the machine applies a value multiplier based on its type and tier. Higher-tier refiners apply larger multipliers, and chaining multiple refiners together compounds these effects.
The key characteristics of refiners are:
- They increase the value of individual ores
- They can be chained together for compounding multipliers
- They process ores one at a time (with some exceptions like the Molten Citadel)
- They are the primary way to boost per-ore income
- They range from C-Tier to S-Tier in power
Refiners are your income multipliers. The more and better refiners you have, the more each ore is worth when it finally reaches your storage or gets sold. Without refiners, you are selling raw ore at base value, which is the least efficient way to earn money in the game.
What Forges Do
Forges are the final processing step in your ore pipeline. They take refined (or raw) ores and convert them into sellable material. While refiners boost the value of ores, forges actually complete the processing cycle and make the ores ready for sale or storage.
The key characteristics of forges are:
- They convert processed ores into sellable material
- They provide a final value boost on top of any refiner processing
- They have storage capacity that determines how much they can hold before selling
- They come in standard and advanced variants with increasing capacity and processing power
- They are essential -- you cannot sell ores without a forge
Forges are your income generators. While refiners make each ore more valuable, forges are what actually turn those valuable ores into money in your account. Without a forge, even the most refined ore in the world just sits there.
Side-by-Side Comparison
Understanding the differences between refiners and forges is easier when you see them laid out directly. Here is a comprehensive comparison of their roles, costs, and benefits:
| Feature | Refiners | Forges |
|---|---|---|
| Primary Purpose | Increase ore value | Convert ores to money |
| Position in Chain | Before the forge | End of the chain |
| Can You Skip It? | Yes, but you lose value | No, absolutely required |
| Cost Efficiency | High (compounding returns) | Moderate (fixed returns) |
| Scalability | Excellent (chain stacking) | Limited (capacity-based) |
| Upgrade Impact | Major (multiplier increases) | Moderate (capacity increases) |
| Risk | Some (Flamethrower destruction) | None |
| Required for Selling | No | Yes |
The Build Priority Framework
Now that you understand what each machine does, here is the framework for deciding which to build at each stage of the game. The general rule is simple: build a forge first, then invest heavily in refiners, then upgrade both in tandem. But the specifics matter, so let us break it down stage by stage.
Very Early Game (BP1-BP2)
At the very start of the game, your first build should always be the basic Forge (BP1). Without a forge, you cannot sell anything, so it is literally the most important machine in your base. Once you have the Forge operational, build the Mineral Washer (BP1 refiner) as your second machine.
The order is: Forge > Mineral Washer > Storage Device
This gives you a functional income pipeline from day one. The Forge converts ores to money, the Mineral Washer boosts ore values before they reach the Forge, and the Storage Device holds excess ores during mining runs.
Early Game (BP3-BP5)
In the early game, you want to balance refiner and forge upgrades. Here is the recommended priority:
- Precision Refiner (BP2) - adds a second value boost
- Advanced Forge (BP3) - increases processing capacity and speed
- Coal Smelter (BP3) - third refiner in your chain
- Advanced Storage (BP4) - more storage for longer mining runs
- Electrode Zapper (BP4) - powerful B-Tier refiner
- Energy Chamber (BP5) - B-Tier refiner with high multiplier
At this stage, you are building out your first real chain while ensuring your forge can handle the increased ore flow. The Advanced Forge at BP3 is important because the basic Forge cannot keep up with the output from multiple refiners.
Mid Game (BP6-BP9)
The mid game is where refiners start to significantly outpace forges in terms of income impact. Your priority should shift toward building up your refiner chain:
- Data Factory (BP6) or Encased Steamer (BP6) - your choice based on ore types
- Industrial Forge (BP7) - essential for handling high-value ore flow
- Flamethrower (BP7) - game-changing A-Tier refiner
- Industrial Storage (BP8) - capacity for the increased ore volume
- Portable Ore Purifier (BP8) and Compression Roller (BP8) - A-Tier refiners
- Pristine Processor (BP9) - high-end processing
The Industrial Forge at BP7 is your last major forge investment for a while. Once you have it, you can focus almost entirely on refiners until the late game.
Late Game (BP10-BP13)
In the late game, your forge upgrades are limited to the Sophisticated Storage (BP11) and Nuclear Forge (BP13). Most of your investment goes into S-Tier refiners:
- Sulfuric Dissolver (BP10) and Advanced Charger (BP10) - top A-Tier refiners
- Blast Smelter (BP11) - first S-Tier refiner
- Sophisticated Storage (BP11) - storage upgrade
- Molten Fabricator (BP12) - S-Tier refiner
- Nuclear Forge (BP13) - ultimate forge
- Chemical Sprayer (BP13) and Mini Microprocessor (BP13) - best refiners
| Game Stage | Build First | Build Second | Ratio (Refiners:Forges) |
|---|---|---|---|
| Very Early (BP1-2) | Forge | Mineral Washer | 1:1 |
| Early (BP3-5) | Refiner | Forge | 2:1 |
| Mid (BP6-9) | Refiner | Refiner | 4:1 |
| Late (BP10-13) | Refiner | Refiner | 6:1 |
Why Refiners Eventually Outvalue Forges
The reason the ratio shifts so heavily toward refiners in the mid and late game is simple math. A forge provides a fixed bonus on top of whatever value your ores have when they reach it. A refiner, on the other hand, multiplies the existing value, and those multipliers compound when you chain refiners together.
Consider two scenarios with an ore worth 100 coins:
Scenario A: All Forges, No Refiners
- Ore enters Forge: 100 coins + 30% forge bonus = 130 coins
- Adding a second Forge upgrade: 100 coins + 50% forge bonus = 150 coins
- The improvement from the second forge: +20 coins
Scenario B: Refiners Then Forge
- Ore enters Refiner 1 (1.5x): 150 coins
- Ore enters Refiner 2 (1.5x): 225 coins
- Ore enters Forge (1.3x): 292 coins
- The improvement from the second refiner: +97.5 coins
As you can see, the compounding effect of refiners creates much larger income gains than forge upgrades once you have a functional base setup. This is why experienced players invest heavily in refiners after securing a basic forge.
Common Mistakes New Players Make
The most common mistake new players make is over-investing in forges while neglecting refiners. It is tempting to build a massive forge setup because forges feel more tangible -- they are where the money actually appears. But without strong refiners feeding value into those forges, you are processing low-value ores through high-capacity machines, which is inefficient.
Another mistake is building too many refiners without upgrading the forge to handle the increased throughput. If your refiners are outputting more valuable ores than your forge can process, you end up with a bottleneck at the forge. The key is maintaining balance: upgrade your forge whenever it becomes the limiting factor in your pipeline.
A third mistake is ignoring storage devices. Storage acts as a buffer between your refiners and forge, ensuring that temporary imbalances in processing speed do not cause ores to pile up or, worse, get destroyed by machines like the Flamethrower. Always keep your storage capacity ahead of your processing output.
The Ideal Build Order for New Players
If you are a brand-new player starting Tectonic Industries for the first time, here is the optimal build order to follow:
- Forge (BP1) - You need this to sell anything
- Mineral Washer (BP1) - Your first value multiplier
- Storage Device (BP2) - Buffer between mining and processing
- Precision Refiner (BP2) - Second refiner in your chain
- Advanced Forge (BP3) - Upgrade to handle increased ore flow
- Coal Smelter (BP3) - Third refiner for better compounding
- Electrode Zapper (BP4) - First B-Tier refiner, major income boost
- Advanced Storage (BP4) - More buffer capacity
- Continue building refiners through BP5-BP7
- Industrial Forge (BP7) - Forge upgrade to match refiner output
This build order ensures you always have the infrastructure to process and sell your ores while steadily increasing your income through refiner chain expansion.
Frequently Asked Questions
Should I build a refiner or forge first in Tectonic Industries?
Always build a forge first. You cannot sell ores without a forge, making it the most essential machine in your base. After the forge, immediately start building refiners to boost your income. The basic Forge at BP1 should be your very first purchase.
Can I play without refiners?
Technically yes, but it is extremely inefficient. Without refiners, you are selling raw ores at base value, which means earning a fraction of what you could be making. Even a single Mineral Washer provides a noticeable income boost that pays for itself quickly.
What happens if my forge cannot keep up with my refiners?
If your forge is too slow to process the ores coming from your refiners, ores will back up in the pipeline. This can lead to wasted processing time and, in the case of the Flamethrower, destroyed ores. Upgrade your forge whenever it becomes the bottleneck in your chain.
Is the Nuclear Forge worth the wait until BP13?
The Nuclear Forge is the most powerful forge in the game, providing the highest processing speed and capacity. However, you should not save up for it exclusively. The Industrial Forge at BP7 and Sophisticated Storage at BP11 are sufficient for most of the game. The Nuclear Forge is an endgame luxury that pushes your already-high income even further.
How do storage devices fit into the refiner vs forge decision?
Storage devices are the bridge between refiners and forges. They hold processed ores temporarily if your forge is busy, preventing backups in your refiner chain. Always build storage alongside forge upgrades to ensure smooth ore flow through your entire pipeline.
Can I skip the basic Forge and go straight to Advanced Forge?
No, you need the basic Forge at BP1 before you can unlock the Advanced Forge at BP3. Base Pass progression is linear, so you must unlock each tier in order. The basic Forge is cheap and essential, so there is no reason to skip it anyway.
