Cobble To Magma
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Description
Adds two new recipes to the blast furnace (NOT the regular furnace). You can now make cobblestone into blackstone, and blackstone into magma. This also lets you turn cobblestone into magma
Versions
Supports Java Edition 1.21.5 - 26.2
Compatibility
Incompatible with anything with the same filenames or using the same recipe inputs in blasting
