The mod “Slime Ore” introduces a new type of ore to Minecraft, which can be found naturally only in swamp biomes. While mining this ore in caves, you will collect several slime balls, even if you don’t encounter any slimes. Once you have gathered enough slime, you can place it in a furnace, and a blast furnace will also work for this purpose.
How does it work?
First, you need to venture into a swamp biome and search for slime, which can be found at layers 0-64. You can collect it either by hand or with a pickaxe.
This mod is compatible only with Minecraft versions 1.13 and above.
