What is Brownstone?
A Guide to the Classic Building Material
Definition
Brownstone is a type of sandstone that is quarried in the northeastern United States. It is a popular building material due to its durability, strength, and rich brown color. Brownstone has been used to construct many iconic buildings in New York City, including the Empire State Building and the Brooklyn Bridge.
History
Brownstone was first quarried in the late 18th century in New Jersey. It quickly became a popular building material in New York City, as it was a relatively inexpensive and durable way to build. Brownstone buildings were often constructed in the neo-Gothic and Romanesque Revival styles, which were popular during the 19th century.
Composition
Brownstone is a sedimentary rock that is composed of quartz, feldspar, and mica. The brown color of brownstone is due to the presence of iron oxide. Brownstone is a strong and durable material, and it is resistant to weathering and fire.
Uses
Brownstone is a popular building material for both commercial and residential buildings. It is often used for exterior walls, window sills, and door surrounds. Brownstone can also be used for interior applications, such as fireplaces and countertops.
Care and Maintenance
Brownstone is a relatively easy material to care for. It can be cleaned with a mild soap and water solution. Brownstone should be sealed every few years to protect it from the elements.
