Bloom of impure iron solidified on a flat surface to form the plano-convex profile and ovate section. The bloom is partly magnetic suggesting that it is not pure iron and therefore more likely Iron Age or Romano-British in date as in more recent times they would have hammered out the slag completely to purify the product (John Smith pers comm). A bloomery is a term used to refer to a furnace used to smelt iron from its oxides and the bloom is the product of that process and usually contains a mixture of fine iron particles, un-reacted iron oxide (ore), slag and charcoal residue. This …

Iron metalworking debris. A large oval-ended furnace bottom or bloom [the finder's identification] with a flat top and near-vertical if irregular sides, formed either in the base of an iron ore burning furnace or in a channel cut to receive molten metal from such furnace. The object was retrieved from a reported depth of c.0.9m, and involved the cooperative labours of two people working at arms' length to extract it from the hole. Dr Kevin Leahy kindly comments that the object has the superficial appearance of cast iron, and that this would carry with it an implication of a date af…

An iron ingot or billet formed from a hammer shaped bloom of probable Early Medieval - early Post Medieval date (AD 550-1550). The ingot is broadly rectangular in plan and triangular in cross section. It has an uneven surface patina and the surviving surface has a series of oval scars, most likely from the spalling of surface corrosion. One end has a flattened and polished removal where the surface had been tested by the finder with an angle grinder. This test suggested that it was formed from wrought iron. Where this test has been undertaken a series of shallow cracks extend in the s…
