Machines Mod: Return of Mythril and Onyx Furnaces for Minecraft
Veteran players of Minecraft will remember the powerful mythril and onyx furnaces from the early SimpleOres era. After major updates, those devices were removed, leaving a noticeable gap in resource processing. The Machines Mod: Return of Mythril and Onyx Furnaces for Minecraft is a compact add-on that brings back those lost mechanics and expands them with new block variants. If you want to maximize fuel efficiency and gain extra resources from every smelt, this mod deserves a spot in your modpack.
Core Functionality and Dependencies
This add-on restores the mythril and onyx furnace functionality that was stripped from SimpleOres 2. It acts as a bridge between classic mechanics and modern Minecraft builds. For Minecraft 1.14.4 and newer, the base SimpleOres mod is required. Starting with version 1.16.3, you will also need the SimpleCoreLib library. Notably, the older SimpleCore API is not required between versions 1.14.4 and 1.16.1, which simplifies the installation process.
The mod does not simply copy the old furnace behavior. It adds new variations, including blast furnaces and smokers crafted from mythril and onyx. This integrates seamlessly with the vanilla fast-smelting system while preserving the unique bonuses of the original materials.
Mythril Machines: Fuel Economy and Speed
The mythril line focuses on rational fuel usage. Each device has a configurable fuel burn time multiplier, set to two by default. This means one piece of coal burns twice as long as it would in a standard furnace. Given that mythril is a rare resource, this efficiency justifies the crafting cost.
Available Mythril Devices
- Mythril Furnace - The base model with doubled fuel burn duration. Ideal for mass smelting of ore into ingots.
- Mythril Blast Furnace - Added for 1.14.4/1.15.2, this retains the fuel bonus and smelts ore twice as fast, similar to its vanilla counterpart.
- Mythril Smoker - Also added for 1.14.4/1.15.2, it provides fast food cooking with the same fuel efficiency bonus.
Crafting recipes mirror the standard furnace patterns. For the mythril furnace, arrange eight mythril ingots in a circle around the crafting grid. The blast furnace and smoker follow their vanilla recipe structures but substitute mythril materials.
Onyx Machines: Chance for Bonus Output
The onyx branch offers a fundamentally different benefit: a probabilistic increase in yield. Each smelt in an onyx furnace has a 33% chance by default to produce an extra ingot. This is not just faster processing; it is a direct resource gain, especially valuable for rare ores like diamonds or ancient debris. The number of bonus items is also configurable, with one extra ingot as the standard setting.
Onyx Device Variants
- Onyx Furnace - The classic version with the probabilistic bonus. Crafted similarly to the mythril furnace but using onyx gems.
- Onyx Blast Furnace - Combines the chance for extra output with double smelting speed. The recipe places an onyx furnace in the center with onyx gems on the sides.
- Onyx Smoker - Provides a chance to double cooked food items while cooking twice as fast as a standard smoker.
This mechanic encourages experimentation. You can risk smelting a rare resource in an onyx furnace for a potential bonus or stick with the consistent fuel savings of mythril. The choice depends on your playstyle.
How to Install and Version Compatibility
Machines supports Minecraft versions starting from 1.12.2, but the full feature set is available on 1.14.4 and above. Before you download Machines Mod: Return of Mythril and Onyx Furnaces for Minecraft, verify that you have the required dependencies installed. For newer builds, check that SimpleCoreLib is present alongside SimpleOres. The developer regularly updates the add-on, so watch for new builds on trusted mod repositories.
To install, drop the mod jar file into your mods folder after confirming the correct loader and Minecraft version. The mod works with both Forge and Fabric loaders, depending on the specific build you choose. If you prefer a more automated setup, some launchers allow direct mod downloads from their interface, which simplifies the entire process of managing dependencies and versions.
Configuration and Fine-Tuning
Both machine types have flexible parameters. In the mod's configuration file, you can adjust the fuel burn multiplier for mythril devices. For onyx machines, you can change the bonus chance percentage and the number of extra items produced. This allows you to adapt the mod to any server balance or single-player experience. You can turn the mythril furnace into a hyper-efficient unit with five times the burn time or make the onyx bonus guaranteed if you prefer consistency over chance.
Final Thoughts
The Machines Mod: Return of Mythril and Onyx Furnaces for Minecraft proves that a small add-on can significantly enrich the gameplay loop. By restoring iconic furnaces and expanding them with blast furnace and smoker variants, it fills the gap left by SimpleOres development. Resource savings, faster smelting, and the chance for duplicate ingots add depth without breaking the vanilla spirit. The developer plans to continue expanding the machine list, so future updates may bring even more useful devices. For now, download the mod, set up your smelting array, and enjoy the efficiency.
