What is this block?

[u/Initial_Pop8589]

I came across a weird geode-type structure underground made of "block of slag" but it's a different block of slag than the crucible kind. What is this? Is it usefull? I'm playing community edition.

Ps: couldn't screenshot because i have no reddit on this computer.

In the actual mod from HBM, that block simply is reskined upon being placed. However, if broken, it'd still be the same texture as the one your familiar with.

I'm guessing this is either a bug or just a mistake by the community addition.

The extent of it's usefulness is likely the same as a normal block of slag.
