After arriving at the manufacturing house, the granite slabs are unloaded onto a conveyor belt where they are cut into smaller slabs. This step is done with a rotary diamond saw. The cut slabs are passed under a varying number of rotating heads from the most abrasive to the least. These pads have water and aluminum or tin oxide powder on them to polish the stone to a smooth, glossy finish. Rock pitching entails chiseling the outer edges of the stone by hand, giving a more defined, personal shape.
