In 1850, Governor William Trousdale chose the Rogersville Marble Company's marble as the state's representative stone for the construction of the Washington Monument. During this same period, marble from Hawkins County, either from Rice's quarry or a rival quarry south of Rogersville, was used in U.S. Capitol extension projects (William Dougherty, the construction superintendent for the Washington Monument, was instrumental in obtaining the marble). Transporting the quarried blocks out of the region presented a major challenge for these early companies. Mule teams, often led by local African American entrepreneurs, carried the blocks to the Holston River, where they were loaded onto flatboats and transported downstream.

Formation
Resources
- Marble occurs in large deposits that can be hundreds of feet thick and geographically extensive. This allows it to be economically mined on a large scale, with some mines and quarries producing millions of tons per year.
Uses
- Most marble is made into either crushed stone or dimension stone. Crushed stone is used as an aggregate in highways, railroad beds, building foundations, and other types of construction. Dimension stone is produced by sawing marble into pieces of specific dimensions. These are used in monuments, buildings, sculptures, paving and other projects. We have an article about \…
Appearance
- Color: Marble is usually a light-colored rock. When it is formed from a limestone with very few impurities, it will be white in color. Marble that contains impurities such as clay minerals, iron oxides, or bituminous material can be bluish, gray, pink, yellow, or black in color.
Reactions
- Acid Reaction: Being composed of calcium carbonate, marble will react in contact with many acids, neutralizing the acid. It is one of the most effective acid neutralization materials. Marble is often crushed and used for acid neutralization in streams, lakes, and soils.
Properties
- Hardness: Being composed of calcite, marble has a hardness of three on the Mohs hardness scale. As a result, marble is easy to carve, and that makes it useful for producing sculptures and ornamental objects. The translucence of marble makes it especially attractive for many types of sculptures.
Advantages
- Ability to Accept a Polish: After being sanded with progressively finer abrasives, marble can be polished to a high luster. This allows attractive pieces of marble to be cut, polished, and used as floor tiles, architectural panels, facing stone, window sills, stair treads, columns, and many other pieces of decorative stone.
Nomenclature
- The name \"marble\" is used in a different way in the dimension stone trade. Any crystalline carbonate rock that has an ability to accept a polish is called \"marble.\" The name is sometimes used for other soft rocks such as travertine, verd antique, serpentine, and some limestones.
