    About

    AE2 Crystal Science is an Applied Energistics 2 addon that restores purified crystals and builds a production and crafting progression around them, from dust through seeds and growth to crystals used in mid- and late-game crafting and energy generation. Its production machines include a Quartz Grindstone for starting dust production, a Crystal Pulverizer for higher-throughput crushing, a Growth Chamber that grows seed stacks in parallel, and an Aggregator for key recipes and seed scaling; configurable machine faces support input, output, bidirectional, or disabled operation. A dedicated Circuit Etcher consolidates processor-crafting steps, while Ender, Meteorite, and Resonating crystal toolsets add further options for AE2 systems. For larger automation setups, the Meteorite Pattern Provider processes patterns internally and holds 63 patterns, while the Resonating Pattern System routes individual ingredients to assigned destinations or sides. The Ender Broadcaster manages wireless channels and allocates them on demand, and the Ender Emitter automatically links nearby ME devices to the network to reduce cabling. Optional integrations add purified crystals when the corresponding mods are installed: Entro Crystal with ExtendedAE, Quantum Crystal with AdvancedAE, Redstone Crystal with Applied Fluix, Ember Crystal with Applied Generators, Rose Quartz with Create, and Irradiated Crystal with Mekanism. The mod also includes JEI and EMI support and an in-game guide covering its systems, machines, and crystals.

    Security

    No harmful code found

    We checked its files and read their code, without running it.

    What it can do on your computer

    Creates settings files
    The mod keeps its settings in the config folder of your game, where you can change or delete them.
    Connects to the internet
    It has code that can go online, for example to check for updates, load skins or send crash reports. Only in its files for Forge 1.20.1. See Privacy

    Why we show this: a mod runs on your computer like any program, so harmful code in it can take your accounts or files. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: malware means no grade, and a Warning in a latest file for a recent Minecraft version lowers it.

    How we checked · All 3 latest files checked, last on 16 Oct 2026
    • FilesWe download the files from Modrinth or CurseForge and look at what is inside them and what their code can do, without running them. Fixed rules tell what is harmful.
      3 latest files: the newest file for each Minecraft version and loader. All 3 are for recent versions. Recent versions: those released in the last 2 years, plus 1.20.1 and 1.21.1, among the most played in modpacks. See each file in Releases
    • Their codeWe turn the code of the files back into readable code and follow what it does, without running it. This shows what it downloads, what it sends and where your login goes.
      Read without running it
    • Author on ModrinthThe disclosure form on Modrinth, where the author declares that the project reads or edits things on your system outside the game. Since 13 Aug 2026, Modrinth's rules require it when this applies.
      Nothing declared about your system outside the game.
    • Looked for, not foundWe looked for these in the file and did not find them.
      Folders outside the game, other programs, updating itself, the webcam or microphone, an AI service.

    Privacy

    We found nothing it sends

    We read its code without running it: it contacts no web address while you play.

    Why we show this: a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.

    How we checked · All 3 files read
    • Files readWe read the code without running it. We list each web address the code contacts while you play, and what it sends. Code that is never used is left out.
      The code of all 3 files, for recent Minecraft versions. See each file in Releases
    • Author on ModrinthThe disclosure form on Modrinth, where the author declares crash reports, usage data and advertisements. Since 13 Aug 2026, Modrinth's rules require it when a project collects data on its users or shows advertisements.
      Nothing declared about crash reports, usage data or advertisements.

    AI

    No sign so far that AI was used to make it

    We looked for AI tools in its texts, files and images and found none.

    We have not read its code history yet.

    No sign of AI in the game

    We found no AI service, AI library or AI model file in its code.

    Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
