The iron furnace was established by Major John Hanbury, and was certainly in production by 1684. Francis Lewis, who built Clydach House in 1693. The furnace was charcoal-powered and by 1704, Hanbury was preparing to produce 300 tons of iron per year. In 1717, the furnace was reckoned to be capable of producing 400 tons per year, and by c. 1720, it was claimed to produce about 25 tons a week in a 40-week campaign. The works closed at the end of the C18, superseded by the coke-fired ironworks at Clydach, set up by 1793.
