Sandustry crackstone has just one HP but ignores the Shovel and Gun. Only a Rocket Launcher, Drill, Laser or Void Gun opens it, and it yields nothing.
Crackstone is a barrier material rather than a resource. It has only one HP, but the Shovel and Gun cannot touch it - you need a Rocket Launcher, Drill, Laser or Void Gun. When it breaks it leaves nothing behind, so its whole role is gating: it walls off areas until you have unlocked a more advanced digging tool.
There is a full walkthrough for this material as well: read the Crackstone guide.
How to get Crackstone
Crackstone has exactly one documented source in the current build: naturally occurring terrain. Everything downstream of it therefore depends on keeping that one step supplied.

Tips
