Calling all geologists/stone experts

[Tidal Bonsai]

I was looking for some stones to make various RoR compositions (trident, cork bark elm, arakawa, etc.)

One type of stone that interested me was basalt. I liked the dark color and it looked to be pretty hard from my searches online. Does anyone know if this is hard enough to withstand pressure over long periods of time without cracking? I don’t want it to break apart when the roots start to put pressure on the stone.

I'm not an expert, but basalt is an igneous rock that has similar durability to granite, so I would imagine that it would stand up to RoR just fine.

Basalt is tough as nails. As long as there aren’t any fissures in the stone it should hold up just fine.

That advice is right on!

Sal, I may have a few pieces of Basalt if you want to check em out.
