Welcome to
Edgar Minerals
Our operation, located in Putnam County, Florida, was established in 1892 by the Edgar family and is proudly one of the oldest continuously operating mining businesses in the state. Initially known as the Edgar Plastic Kaolin Company, and later as the Feldspar Corporation’s Edgar Facility, our focus began with the production of white kaolin clay, while the sand in our reserves was originally considered a by-product of the clay process.
Today, Edgar Minerals continues the tradition of producing high-quality kaolin clay, along with premium and custom-blended sand products for industrial and construction applications. With over 2,500 acres of mineable land, Edgar Minerals is well-positioned to supply both local and global markets with top-tier sand and clay for many years to come.
The Edgar Plastic Kaolin (EPK) Company, founded in 1892 by Charles S. Edgar, is reputedly the oldest continuous mining operation in Florida.
The Edgar family originally farmed in Middlesex County, New Jersey, near Metuchen. In the 1870s, after discovering clay on their farm, Charles S. Edgar and his two brothers established the Edgar Brothers Clay Co. They began mining the clay during the winter months when farming was less demanding. Using shovels, they dug the clay, loaded it onto wagons, and transported it 12 miles to Perth Amboy, where it was sold to scows bound for Trenton, New Jersey. There, the clay was used to manufacture terra cotta, pottery, bricks, and saggers—fire-proof containers for enclosing ceramics during firing.
Recognizing that most ceramics and china in the United States were made from clay imported from England, Charles saw a significant opportunity to find a domestic source. During his travels, he spent time prospecting for suitable clay deposits. While on a business trip to Boston, he learned of potential fine clay deposits in north-central Florida, which eventually led to the establishment of the EPK Company.
