Want to see a pretty thing?

@OogieBoogie Volcano 😎

@Pfuzylogic I.wa jist making a hypothetical visual analogy,

But really,?!?!

What part?

@OogieBoogie
The lava flow.
It changes in shape and this looks like it solidified after running off the volcano.

@Pfuzylogicso. It's UN aerated pumice stone?

@OogieBoogie
“In pumice occurring among old volcanic rocks, the cavities are usually filled with deposits of secondary minerals introduced by percolating water. ... Pumices are most abundant and most typically developed from felsic (silica-rich) igneous rocks; accordingly, they commonly accompany obsidian.”
Edit: doesn’t look like they are the exact same thing but I like your observation.

@Pfuzylogic so, they're muddy airy obsidian?🤔

@OogieBoogie
That sounds about right.
Pumice must be more common I would guess.

@Pfuzylogic well, it's I'm my bath, so, I'd say so!!? 😏

@OogieBoogie
any multi color black
can’t help but look excellent!

@Pfuzylogic I adore black opals myself, just stunning!!!

@OogieBoogie
I would totally agree with that along with fire and Tanzanian
