Basalt Settings

When laser cleaning basalt, it stands out from softer stones like limestone because of its dense, hard nature. I've seen this density help absorb laser energy quickly, so contaminants lift off without much residue left behind. That makes the process efficient for tough buildup in construction or heritage sites. But watch out mid-way—basalt tends to fracture if heat builds unevenly, unlike those porous limestones that just fizz away. This works best when you keep passes steady and overlap spots well, solving the brittleness by spreading the energy. In my experience, it preserves the stone's strength for marine or aerospace uses, avoiding cracks that could weaken structures later. Just ease into higher intensities gradually to handle its heat resistance without surprises.
