Pumice: A Nether Sponge Alternative
Clearing lava in the Nether has always been an almost impossible and extremely difficult task. Everything changes with the introduction of Pumice!
IMPORTANT: REQUIRES FABRIC API
Crafting and Usage
Pumice is crafted by surrounding a sponge with eight basalt blocks. This innovative block functions similarly to a regular sponge but is designed to absorb lava instead of water.
After successfully absorbing lava, Pumice transforms into molten pumice. You need to be extremely careful with this state - molten pumice retains high temperature and causes damage upon contact.
Renewing Usage
To return molten pumice to its original state, simply use a bucket of water in the Overworld. The process will consume the water but will return you a fully functional Pumice block ready for further use.
If the need for this block disappears (although it's hard to imagine such a situation), it can be recycled back into a regular sponge using a stonecutter.
