I mean, what mineral is it? I have “some” in my world’s nether (Netherlicious mod adds it, or Et Futurum, or both). I want to spend much energy to refine it into something useful. Maybe somebody has a good idea what it could be?
For example, Netherrack is mostly sulfur, some redstone, coal and gold.
That is actually a good question, I have no Idea what it could be. We could go with the GameTheory that the Nether was frozen over a while ago and that is how Blackstone formed, similar to how Basalt formed when Ice and Soulsand got hit by Lava.
Aaaaand I just remembered you can infinitely generate Blackstone similar to how you can Basalt and Stone! So I cant just give something useful from that!
Any suggestions as to which things you should get out of Blackstone?
Blackstone is closer to Obsidian considering how shiny the rock is. And Netherlicious has a special Spectral Dew Cobblegen alike Recipe for Blackstone, which by the way also has an Extruder Generator in GT6 that DOESN’T require Spectral Dew to exist, so it also works for Et Futurum Requiem. But yeah its available through bartering too in Vanilla, so the Cobblegen way is not that exploity.
Not to mention Soulsand is already the Coal thing, so no doubling up on that one.
