New Galilee, Pennsylvania
Clay was an abundant resource in Beaver county. According to the 1955 circular of the Pennsylvania Geological Survey, In 1955 Beaver County produced 13.7% of Pennsylvania's total clay output. There were 13 companies that mined clay in Beaver county at that time. Two of these companies, The Negley Fire Clay Co. and Ralph A. Veon, Inc. mined fire clay of the plastic variety from open pits and marketed the output for use in manufacturing fire brick and block, foundries, and heavy clay products. In addition, Ralph A. Veon, Inc., mined and sold fire clay of the burley variety. In 1955, New Castle Refractories mined stoneware clay from an underground mine near New Galilee for use locally in manufacturing pouring channels

Load Brook was developed from a farm to a minor industrial site in the late 19th and early 20th centuries. A "pot clay" mine (pot clay – a type of fireclay from the Stannington pot clay bed) was developed to the southwest in the 1850s by William Trickett, a local farmer. Trickett obtained rights to mine pot clay from the landowner, the Duke of Norfolk in 1852 and was mentioned in the Sheffield Trade Directory of 1862 as a clay merchant. William Trickett died in 1890 and the business was continued by his three sons, William, Benjamin and Matthew under the name of B. Trickett & Co.
