Rock Types That Can Be Sandblasted

Question: Eric, I am just starting a sand blasting rock engraving business. What type of rocks can I engrave/ have sandblasted?

My Answer: You can blast all types of rock, granite, etc. Basically any type can be sandblasted but brittle stone like sandstone or porous surfaces may not be ideal. A quick look at the rock’s surface will give you an idea if its a good candidate for sandblasting.

A smoother surface is better because the stencil will stick to the rock better and prevent abrasive media from engraving in areas that you don’t want it to. While a more rough or porous surface will be harder for the stencil to stick.

That should give you an idea of the best types of rock that can be sandblasted. This process is commonly known as sandcarving.
