Anthracite iron technique & process, which he had conceived in an attempt to improve the efficiency of conventionally fueled furnaces. The first person to employ the hot blast technique to anthracite smelting was Dr. Frederick W. Gesenhainer, who filed for a patent on the process in 1831 and received it in 1833. In 1836, he tried smelting anthracite iron on a practical scale at his property, Valley Furnace, near Pottsville, Pennsylvania, while in the same year White & Hazard's LC&N Co. built two experimental blast furnaces in Mauch Chunk. He produced a small quantity of iron, but due to mechanical breakdowns, could
