SimpleFactories
by JustMrKoala
SimpleFactories adds two NeoForge machines that turn items into crystallized copies at a rare chance, and an Extractor that produces normal copies of a crystallized seed.
What it does
The Crystallizer takes an item into its input slot, runs on fuel placed in the fuel slot, and consumes its input slowly. Each processed item has a 1 in 1000 chance to produce one crystallized version, which appears in the output slot. Crystallized items carry a Crystallized enchantment with a purple glint and matching tooltip text, so they can be told apart from ordinary stacks.
The Extractor takes one crystallized item into its seed slot and keeps that seed indefinitely. Once fuel is added, it produces one normal copy of the seed every few seconds, dropping it on the ground above the block. Its output keeps going for as long as fuel lasts, and the seed itself is never used up.
The mod works with vanilla and modded items that the furnace-compatible fuel system accepts. It has no dependencies beyond NeoForge and is lightweight enough for small servers. Builds exist only for 1.21.8, with version 1.0.0 as the latest file on the alpha channel. Both the server and every player need the mod, since the machines run on the server side.
