Granite as a monumental stone
The U.S. Bureau of Mines does not classify all granites suitable for monumental stone. According to the Bureau’s standards for class 1 granites, they must:
- Meet exacting requirements, such as uniform texture and color
- Freedom from flaws
- Suitable for polishing and carving
- Resistance to weathering.
In a test completed on all recognized monumental grade granites by the U.S. Bureau of Mines, they stated the following. Many trade names are applied to memorial stones and prospective users may raise questions as to whether these names, varieties, or types are superior to others. The Bureau of Mines has no data indicating that any of them are more enduring. In fact, all of the monumental granites produced by reputable firms in the well known regions last so long with little visible change that the factor of endurance should scarcely be given consideration in making a choice. Selection may therefore be made on the basis of color, texture, design, and workmanship that suit individual taste.
