Not all rock is as dense as the granite and marble we use to build with. Some rocks are much more porous and permeable. This permeability allows air and water to enter into the rock body, where physics and chemistry take over to explode the rock when it heats up.
Sand the quartz surface with a hand-held sander, using the 200-grit sandpaper pad. Use smooth, even strokes and make sure to sand the entire surface. As you work, you may need to wipe away dust with rags. Repeat this process using increasingly finer grit sandpaper pads, ending with the 800-grit paper.
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) mineral particles or rock fragments (clasts) or organic material. They make up about 20 to 25 percent of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface, as seen in the Goldich ...
Why is quartz so common in sand? It is a widespread rock-forming mineral and it is also extremely resistant to weathering. Quartz has no cleavage. So we never see planar surfaces on fresh fractured grains. Rocks that contain lots of quartz are sandstone, .
These can be as fine as sand or grainy or coarse like gravel. The finer the particles, the more uniform the color of the slab will result.

It is easiest to spot in white quartz, though quartz can come in a range of colors including yellow, pink, purple, grey, or black.
Quartz sands, which are high in silica content, are used to make glass. When quartz sands are crushed they produce particles with sharp, angular edges that are sometimes used to make sandpaper for smoothing wood. Some quartz sand is found in the form of sandstone.
