Sandblasting is the process that actually does the cutting of the granite. After the stencil has been glued back into the areas we’ve steeled and the letters and designs cut and pulled, the memorial is now ready to be sandblasted. We again put the memorial in our sandblast room. We sandblast using the aluminum oxide and hitting the exposed areas at about 80psi. As we work our way over the lettering and designs, the aluminum oxide gradually cuts or blows away the granite that is exposed. As the aluminum oxide slowly cuts deeper into the granite, it will eventually get to a point or V shape. From there, we continue to cut deeper, which forces the granite to cut back out at the bottom. This helps in the legibility of the lettering and designs by creating a natural shadow.
