AlelChemist — Fantasy Chemistry Datapack
What if alchemy was real science?
If you are going to play AlelChemist on Minecraft 26.3 or later
The latest beta version of the project makes the description below outdated. Please read the changelog for AlelChemist 0.8.AlelChemist recreates the process of scientific experimentation in Minecraft. Over 100 reagents combine inside the Aleldron to produce reproducible reactions — but why and how they work remains unknown. Your role is to hypothesize, test, and gradually uncover hidden principles through observation and analysis.
There are no recipes — only patterns waiting to be discovered.
Every reaction follows consistent, logical rules, but their exact mechanisms are concealed. Experiment, collect data, and build your understanding piece by piece.
Designed for true experimenters, not mere crafters.
This datapack prioritizes curiosity, critical thinking, and the thrill of discovery over grinding or rote memorization.

Key features:
- New workstation: the Aleldron — a custom cauldron for your experiments
- In-game starter notes, accessible from the pause menu
- Over 100 reagents, with more to come
- 20 reaction types, most with multiple variations
- Some reactions may be dangerous — explosions, poisons, and worse
- Others might be surprisingly useful — if you can figure them out
- And secrets
