Granite

- a coarse-grained igneous rock cooled and consolidated at depth in the earth's crust. Three essential minerals must be present; feldspar, mica and quartz. (Illustration)
It can be very smooth faced, ie axed, fine axed, double axed or polished. The first Aberdeen granite masters actually went to London to view Egyptian artifacts to attempt to relearn the art of polishing. Polished granite is frequently chosen for headstones, and can provide unfortunate contrasts with indigenous building materials in historic churchyards.
