Random Smelting
by Tviz
Random Smelting swaps the vanilla smelting results in Furnace, Blast Furnace and Smoker for a deterministic random item drawn from the world's seed.
What it does
Smelting an item in a furnace, blast furnace or smoker no longer yields the normal vanilla result. Instead the mod produces an item chosen from a recipe set that is generated from the world's seed material, so each new world gets its own set of smelting recipes.
The same input always gives the same output within a given world, and a new world produces a different recipe set. Items are grouped by value category so the economy stays balanced: cheap items turn into other cheap items, while valuable items are exchanged for other valuable ones. The mod automatically supports items added by other mods, and its configuration calculates the recipes on demand.
Random Smelting is a client and server mod, so both the server and every player need it. It is published for Fabric only, for 1.21.1, under All rights reserved, and is not open source.
Key features
Seeded smelting results
Each smelted item produces a result drawn from a recipe set tied to the world seed, not the vanilla output.
Per-world recipe sets
Creating a new world generates a different set of smelting recipes, so results vary between worlds.
Value-based grouping
Items are sorted into value categories, so cheap items turn into cheap items and rare items into rare items.
Support for modded items
Items added by other mods are included in the recipe calculation automatically, with no manual setup required.

Use cases
Changing a world's economy

Who it’s for: Players and server owners who want furnace, blast furnace and smoker outputs to differ from vanilla and to change from one world to the next.

What the author says
Random Smelting replaces vanilla smelting with a completely new system. Every item and block can be smelted in a Furnace, Blast Furnace, or Smoker, producing a deterministic random item instead of the normal result.
