Bog iron is also believed to have been used at a bloomery near Golspie, Sutherlandshire. |
The final version of this kind of bloomery hearth survived in Spain until the 19th century. |
The authority's archaeologists have since found evidence of the bloomery forge, a dam, a wheelpit, and slag heaps. |
In 1408 the bishop of Durham established the first water-powered bloomery in Britain, with the power apparently operating the bellows. |
When a Catalan forge is employed in making blooms, it is called a bloomery. |
Work went on continually so the fire never went out, which meant a typical bloomery had an output of about 600 kg of iron a day. |
