SimpleFactories

SimpleFactories adds two machines that turn rare chance into infinite resource production. Crystallizer Consumes items from the input slot and fuel from the fuel slot. Every processed item has a 1/1000 chance to produce one crystallized version. Crystallized items gain the "Crystallized" enchantment, purple glint, and tooltip text. Extractor Place one crystallized item in the seed slot and fuel in the fuel slot. The seed remains forever. Every few seconds the machine produces one normal copy of the seed item and drops it as an entity above the block. How to use

Place a Crystallizer. Put any stack of items in the input slot and fuel in the fuel slot. Wait. Input depletes slowly. Very rarely a crystallized version appears in the output slot. Move the crystallized item to the seed slot of an Extractor. Add fuel to the Extractor. Normal copies of the original item drop above the block indefinitely while fueled.

Features

Works with any vanilla or modded item Accepts any furnace-compatible fuel Crystallized items show purple glint and "Crystallized" tooltip No dependencies Lightweight and server-friendly

Forge / NeoForge 1.20.1 – 1.21.x Tested in singleplayer and small servers.
