History
John Bedford came from Kings Norton near Birmingham to Monmouthshire, and moved to Cefn Cribwr c.1771-2, where he started an ironworks, a colliery and a brickworks close to the same site. Calcining was a later development in the early technology of iron founding, which combined coke with limestone products. One battery of coking ovens lies some 10m further S, served by the same tramway - these now survive only at foundation level. Bedford died in 1791, and the ironworks with the other enterprises on the same site, were taken over by his son, then by Bryant & Co in 1824, possibly in anticipation of the opening of the Duffryn, Llynfi and Porthcawl Tramway in 1828, relocating the iron production on another site nearby. The ironworks was acquired by Ogwr Borough Council in 1987 and has since been consolidated and laid out as an important element in the Waun Cimla Country Park.
Exterior
Built of local sandstone, and brick made on site. The structure consists of a central segmental brick-arched tunnel vault with finely laid facing stone voussoirs, through which ran the plateway directly to the upper part of the charging house. The plateway consisted of simple rectangular section fish-bellied rails in 4ft (1.22 metre) lengths set to a 4ft 6in (1.4 metre) gauge and held by cast iron chairs each twice bolted to large stones set in the track formation. To either side of the central arch, similar but slightly narrower arches open from the N side to the calcining kilns, each consisting of a brick lined 'V'-shaped oven. The upper section of the kilns is lost.
Interior
Reason for designation
Included at Grade II as an important element in the small ironworks of the late C18, which has survived largely unaltered as production moved elsewhere. Of group value with other elements of the ironworks.
