Example project from our rock blasting course using sandblast filler for a porous brick surface.
Eric-
My wife and I are starting up a small business doing glass and stone etching and carving, mainly using sandblasting.
I’ve read some articles on the difference between dead rock and living rock, but have found nothing on how to tell if there dead or living and if sandblasting is better on one then the other. Have you had any experience on this?
Thanks,
Ryan
Hi Ryan,
I am not too knowledgeable on blasting living rocks but from what I am aware, I thought living rock was typically porous rocks from the ocean.
I do know that if the rock is porous, then it would not be ideal to sandblast for many reasons. One is, I don’t know how the stencil would stick to the surface. Of course, you can try to use a heavy sandblast filler as explained in our course, how to sandblast rocks but it will be troublesome getting the filler out.
Not sure if that helps you, but smooth rock is ideal for sandblasting.

I would have thought ‘living’ rock is part of the landscape, cliff face or whatever (before it’s quarried)
‘Dead’ rock is anything after it’s quarried and dried out (I studied geology for 4 yrs, living and dead rock are not ‘scientific’ terms)
Thanks Peter. That makes sense.
