History

Founded in 1868, Washington Mills began as Washington Mills Emery Manufacturing Company. It was the first abrasive producer in the United States and its sole product at that time was imported Turkish Emery Ore – a natural abrasive that was crushed and sized primarily for the polishing of farm tools. By 1929 sales of Turkish Emery had fallen as more consistent man-made materials in the form of electrically fused aluminum oxide became available. In order to keep pace with the superior fused materials, Washington Mills converted its emery plant into a more modern plant suitable for processing the new fused materials.
