U.S. iron mill

In 1817, the first U.S. mill to roll and puddle iron was opened. Plumstock Rolling Mill, built by pioneer ironmaster Isaac Meason (15 Aug 1743 - 23 Jan 1818), stood at Redstone Creek, Pennsylvania. A puddling furnace reduces the carbon content in cast iron to produce malleable iron. The mill produced wrought iron by roll milling rather than than hammer forging. It was destroyed by floods in 1824. Meason had led the iron and steel industry since 1791 when he establishing the first commercially successful iron furnace and forge west of the Alleghenies. A rich man, he eventually owned 20,000 acres of land, six iron furnaces, toll ferries and bridges, two sawmills, grist mills, the entire town of New Haven and property in Kentucky.«[Image: Isaac Meason commissioned architect Adam Wilson to build his Georgian-style mansion (1802), which is now a National Historic Landmark.]
