Over a century strong.
More than a century of evolution and growth.
In the late 1800s, pioneer Henry Harrison Hunter mined and processed his first sand sample by hand near Berkeley Springs, West Virginia. Hunter entered this sand sample in the Chicago World's Fair. He won a blue ribbon and the medal of excellence for the sand's purity. A small plant was built to mine the deposit to produce silica sand for glass manufacturing.
The company as it exists today has undergone many developments over the years, including the merging of the Pennsylvania Glass Sand Corporation and Ottawa Silica Company to form what is now known as U.S. Silica Company. Today, we have more than 27 production facilities across the country. We upgrade our plants and equipment regularly, and invest in our employees to ensure that our knowledge base remains state-of-the-art.
