Lava Rock & Wet Saws

[Carey]

Have used my trusty HD wet saw cutting some lava slabs, but they were neither thick, nor that big, less than 18" prior to cutting... but it also depends on the stone picked.... the more frothy pumice stone would seem to be harder to cut with out crumbling, the pieces I cut were more like blue rock & more like thick porcelain/granite to cut (which I prefer...as you get a nice ,solid, smooth cut...

I always wear face protection & really needed the gloves for the lava rock, as the slab edges were sharp

Have also seen guys carving pounders & such from lava stones using a grinder....again, it depends on the rock you start with... but the pounders came out looking really nice
