CauldronFix
by ryan100c
CauldronFix changes how cauldrons fill, empty and react to tools, adding new fill levels and recipes for cobblestone, stone, obsidian, gravel and burnt fills.
What it does
The mod extends vanilla cauldrons with extra contents and interactions. Cauldrons can be filled with cobblestone, stone, obsidian, gravel and burnt material, and each fill can be emptied back into a block. Water placed above a lava cauldron produces lava, and a lava cauldron at levels one to three of water produces lava as well. Shapeless crafting recipes combine a cauldron with a cobblestone, stone or obsidian item to produce the matching full cauldron.
Some interactions depend on the tool used. A diamond pickaxe with silk touch can lift a filled cauldron, a shovel-like item can interact with cauldrons, and a mace used on a full cobblestone cauldron triggers its own result. Dispensers can also interact with cauldrons, so automated setups can fill or empty them without a player present. The mod runs on Fabric, is published for 1.21 and 1.21.1, and is released under the Creative Commons Attribution Non Commercial Share Alike 4.0 license, so it is not open source.
Key features
Stone-family cauldron fills
Cobblestone, cobblestone slab, stone, obsidian and gravel can each fill a cauldron, and emptying leaves the source block behind.
Lava from water cauldrons
Water above a lava cauldron produces lava, and the level one to three water cauldrons produce lava as well.
Shapeless cauldron recipes
Cauldron combines with a cobblestone, stone or obsidian item in any arrangement to produce the matching full cauldron.
Tool-based interactions
Silk touch with a diamond pickaxe, shovel-like items and a mace each trigger specific cauldron results.
Dispenser interaction
Dispensers can fill and empty cauldrons, allowing automated fills without a player standing nearby.

How it compares
Milk in Cauldron is a Fabric mod for client-side use only, for 1.21.9 – 1.21.11, released under the Apache License 2.0 and open source. Chaotic Tweaks is also Fabric, server-side only, for 1.21.10 and released under the MIT License, but it is not open source.

CauldronFix differs by targeting 1.21 – 1.21.1 and needing both sides.
