Warwick Furnace was the fifth cold-blast charcoal furnace built in PA and the third in Chester Co. Built by the heirs of ironmaster Samuel Nutt on French Creek and managed by John Potts of Pottstown, its early ironmaster was Colonial America's first female industrialist Anna Nutt. It manufactured the first Franklin stove in 1740 and made cannon for the defense of Philadelphia during the Revolution. In its heyday it had thousands of acres of coaling lands and was the largest producer of Colonial iron in PA. It closed in 1867, but had been active for 130 years. This is its story.
