How is Granite Processed?
Granite is natural rock formed over millions of years. Granite is the signature rock of the continents. More than that, granite is the signature rock of the planet Earth itself. The other rocky planets—Mercury, Venus, and Mars—are covered with basalt, as is the ocean floor of Earth. But only Earth has this beautiful and interesting rock type in abundance. Granite is the most widespread of igneous rocks, underlying much of the continental crust. Granite is an intrusive igneous rock. Intrusive rocks form from molten material (magma) that flows and solidifies underground, where magma cools slowly. Eventually, the overlying rocks are removed, exposing the granite. Granites usually have a coarse texture (individual minerals are visible without magnification), because the magma cools slowly underground, allowing larger crystal growth.
Granite is mined in huge blocks, it is then cut with diamond blades into smaller blocks. These blocks are then cut into slabs of various thickness. The granite is polished to a very high shine and then processed and cut into various shapes to make your tombstone.
