Elementarium

The whole periodic table, real ores with real chemistry, and everything you add works exactly the same way.

Elementarium is a data-driven material library for modpack creators. Out of the box you get all 118 elements as ingots, plates, gears, dusts, fluids and more — plus 60+ real-world ores (magnetite, bauxite, cinnabar, wolframite…) with true chemical compositions, world generation, and a multiblock Mineral Analyzer that can study any ore from any mod. Recipes, tags, loot and a clean consistent look are already wired up.

Need your own alloys or ores? Add them in JSON or KubeJS with a few lines and get the full treatment for free. Don't need something? Turn it off in one config file — every single feature has a switch.

The point is: no two mods shipping three different Steel Plates anymore :)

Highlights

• All 118 elements included by default, fully configurable.
• Every material becomes a full set of forms automatically:
  • Ingot, Nugget, Block
  • Dust, Small Dust, Tiny Dust
  • Plate, Double Plate, Rod, Gear, Wire
  • Fluids: Molten, Liquid, Gas (each with a fluid block + bucket)
• 60+ real ores — one real mineral per element, placed with geological logic across the Overworld, Nether and End.
• Real chemistry — every mineral carries its true formula (malachite is Cu₂CO₃(OH)₂, not "copper rock").
• Mineral Analyzer — a multiblock scanner that tells you where any ore generates. Works on ores from any mod.
• Recipe unification built in — Almost-Unified-style: duplicate materials across mods resolve to one item, automatically.
• Recipes generated by default — the full compaction web, ore smelting/blasting, everything.
• Cross-mod c: tags on everything (c:ingots/steel, c:ores/tin, c:raw_materials/tin, …) so your items and other mods' items just work together.
• Add your own materials AND ores in seconds — JSON or KubeJS, same result: real items with recipes, tags, models and worldgen.
• Fully modular — disable any material, form, mineral or feature, globally or individually, from one config file.
• JEI built in — element info pages plus every item and recipe in the catalog.
• In-game periodic table — a collectible element browser (default key: P).

Kinds of Ore — real minerals, real chemistry

You don't mine "Tin Ore" in real life — you mine cassiterite. Elementarium ships 60+ real minerals, one per element, each placed where geology says it belongs:

Every ore:

• Drops a tinted Raw Mineral (silk touch drops the block, Fortune works) — or drops itself, if you configure it that way.
• Smelts/blasts into its primary element.
• Carries its real chemical formula in the tooltip — and the full composition feeds elementarium:contains/<element> tags, ready for byproduct processing.
• Gets baked textures per host rock (stone / deepslate / netherrack / end stone) from a single overlay + your mineral color.
• Generates in the world with per-mineral vein size, count, height range and distribution — all editable.

Name things your way

• namingMode: "real" → Malachite Ore, Raw Cassiterite (immersive)
• namingMode: "simple" → Copper Ore, Raw Tin (familiar)
• renameVanilla: true → vanilla ores get their real names too: Iron Ore becomes Magnetite Ore, Raw Iron becomes Raw Magnetite (display only — nothing breaks)

Iron, copper, gold, coal and lapis are not duplicated: their minerals exist as rename-only entries so vanilla stays vanilla.

The Mineral Analyzer

Elementarium's single machine — and you can't craft it. Stack a Multiblock Casing with a Lift Post on top and assemble it with the Screw Gun (from Navaronee CoreLib). Breaking it gives your blocks back.

Feed it Forge Energy, insert any ore block from any mod, and it reads the actual world generation data of your instance:

• Which dimensions the ore generates in
• Height range (real Y values, resolved from the actual placed features)
• Vein density
• Chemical formula (for Elementarium minerals)
• A free-text description — written by you, the pack creator, in config/elementarium/descriptions.json, per block id or per tag. Document your whole pack's ores in one file.

No hardcoded list: if a mod adds an ore, the Analyzer can analyze it.

Recipe unification

Elementarium is the material backbone of your pack. When two mods both add a Tin Ingot, recipes across the pack are rewritten at load time so that:

• Outputs resolve to one dominant item (Elementarium's, or vanilla for iron/gold/copper)
• Inputs widen to the c: tag, so every equivalent item stays usable
• Duplicate recipes are removed, and non-dominant duplicates are hidden from JEI

It understands machine recipe formats generically (validated with Mekanism, Immersive Engineering and Create) and it's all configurable — teach it new recipe fields, exclude recipe types, or turn it off entirely.

Add a material

Ready-made templates ship with the mod. On first launch, look in config/elementarium/examples/ for bronze.json and material.js.

With JSON — no other mods required

Drop any *.json file into config/elementarium/:

{
  "materials": [
    {
      "name": "bronze",
      "displayName": "Bronze",
      "color": "#CD7F32",
      "style": "metallic",
      "state": "solid",
      "forms": ["ingot", "nugget", "block", "dust", "plate", "rod", "gear", "wire", "molten"]
    }
  ]
}

That's it — restart and you have tinted Bronze items, a Bronze block, a molten Bronze fluid + bucket, all the compaction recipes and every c: tag.

With KubeJS — same thing, in a script

Put this in kubejs/startup_scripts/:

Elementarium.create('adamantium')
    .displayName('Adamantium')
    .color('#7BE3D8')
    .style('shiny')
    .state('solid')
    .forms('ingot', 'nugget', 'block', 'dust', 'plate', 'rod', 'gear', 'wire', 'molten')
    .register()

Scripted materials merge on top of JSON, so a script can override a default.

Add an ore

Same philosophy, same two ways. Templates ship in config/elementarium/minerals/examples/ (ilmenite.json and ore.js).

With JSON

Drop any *.json file into config/elementarium/minerals/:

{
  "minerals": [
    {
      "name": "ilmenite",
      "displayName": "Ilmenite",
      "formula": "FeTiO₃",
      "composition": { "titanium": 1, "iron": 1, "oxygen": 3 },
      "oreStyle": "normal3",
      "rawStyle": "raw_1",
      "color": "#4A4E55",
      "variants": ["stone", "deepslate"],
      "miningTier": "iron",
      "drop": "raw",
      "worldgen": { "veinSize": 9, "veinsPerChunk": 8, "minY": -64, "maxY": 112, "distribution": "triangle" }
    }
  ]
}

You get: ore blocks with baked textures for each host rock, a tinted Raw Ilmenite, loot with silk touch + Fortune, smelting into titanium, all the c:ores / c:raw_materials / contains tags, and world generation — from one JSON entry.

With KubeJS

Elementarium.createOre('ilmenite')
    .displayName('Ilmenite')
    .formula('FeTiO₃')
    .component('titanium', 1)   // first component = smelting target
    .component('iron', 1)
    .component('oxygen', 3)
    .color('#4A4E55')
    .oreStyle('normal3')
    .drop('raw')
    .variants('stone', 'deepslate')
    .miningTier('iron')
    .worldgen(9, 8, -64, 112)
    .register()

Modularity — everything has a switch

One file: config/elementarium/config.json. No need to edit the datasets.

{
  "disabledMaterials": ["titanium"],
  "disabledForms": ["wire"],
  "materials": { "iron": { "disabledForms": ["gear"] } },

  "ores": {
    "enabled": true,
    "namingMode": "real",
    "renameVanilla": false,
    "recipes": true,
    "worldgen": { "enabled": true },
    "disabledMinerals": ["lorandite"],
    "minerals": { "cassiterite": { "veinsPerChunk": 4, "disabledVariants": ["deepslate"] } }
  },

  "analyzer": { "enabled": true, "energyCapacity": 80000, "energyPerAnalysis": 4000 },

  "unify": { "enabled": true }
}

• Disable whole materials, forms (globally or per material), minerals, ore variants, worldgen (globally or per mineral), the analyzer, the unifier, ore recipes — anything.
• Override any mineral's vein size, count and height without touching the dataset.
• Removed content disappears cleanly — items, recipes, tags, loot, worldgen and periodic-table entries all go together, no leftovers.
• The full mineral dataset itself lives in config/elementarium/minerals/minerals.json — it's the default, and it's yours to edit.

Tweak the recipes

Every Elementarium item is a normal, c:-tagged item, so CraftTweaker and KubeJS can retweak the generated recipes with zero special support:

// CraftTweaker: replace the default block recipe
recipes.remove(<item:elementarium:steel_block>);

Want to create new materials or ores from a script? Use JSON or KubeJS (above). CraftTweaker is for tweaking existing content, since its scripts run after the game's registries are built.

Built for modpacks

Most tech mods reinvent the same basic resources — duplicate items, clashing textures, incompatible IDs. Elementarium is a shared material foundation: one naming scheme, one look, one set of tags, one unifier for your whole pack. Define materials once, keep everything consistent, and let mods speak a common language instead of each rolling their own Copper Gear.

Compatibility

Note for 1.20.1 (legacy): the old Forge 1.20.1 version uses the ptmaterials: id and forge: tags, and does not include ores, worldgen or the Mineral Analyzer. All new development targets NeoForge 1.21.1 with the elementarium: id and c: tags.
