Iron Smelting

The very first smelting of metallic iron from native iron ore in North America took place in northern Newfoundland some time about 1000 AD. This Norse occupation site, now thought to be the actual LiefsbuDir of the Sagas, is located at L'Anse aux Meadows. The first blacksmithing work also was undertaken there.

This disk is a compilation of a number of materials related to an ongoing experiments concerned with Iron in the Viking Age. It includes the primary documentation of a series of smelts using elements of the technology available in Scandinavia circa 1000 AD. The core team involved in these smelts are made up of members of the Dark Ages Re-creation Company of Ontario, Canada. There are also a series of illustrated articles outlining the work and equipment of the Norse Blacksmith.

Hugely expanded from the initial 2004 version, V2 details the 22 experimental smelts up to November 2006 plus additional materials. The collection now contains almost 2000 images, most of them large scale (20 x 14). It also contains a number of working drawings and plans. Several articles included are primary rough drafts for papers and reports currently under production.

Iron Smelting in the Viking Age is primarily the work of Darrell Markewitz. The disk also includes a modified portion of the original DARC web site, created by Neil Peterson, with additional photographs by Karen Peterson. Some artifact reference images are included, these are attributed to the original sources and photographers. Before copying any materials included on this disk, individuals are cautioned and asked to read the Copyright Provisions.

Darrell Markewitz is an Interpretive Program Designer, a specialist in the Viking Age. He created the 'Norse Encampment' series of programs, starting in 1992. The culmination of this work was the 'Viking Encampment' living history presentation for Parks Canada at L'Anse aux Meadows NHSC. In 2003 he designed and produced the exhibit 'World of the Norse' for the Cranbrook Institute of Science. He was part of the original concept team for the Smithsonian's 'Vikings - North Atlantic Saga'. He also worked on the educational programming related to the Newfoundland Museum's 'Full Circle - First Contact'. In 2000 he created and delivered the college level program 'Interpreting the Viking Age'.

As a working blacksmith, his experience goes back over a quarter century. Since 1992 he has operated the Wareham Forge in Grey County, Ontario. Work is split between consulting with museums, teaching and creating original art metalworks.

He has worked as an artisan / interpreter at a number of historic sites throughout North America and over a range of time periods. He was fundamental in the creation of the Dark Ages Re-creation Company, and remains a driving force behind the group's museum presentations and experimental archaeology projects.

Neil Peterson is a software development Project Manager. His interest in Viking Era Denmark and Iceland goes back into the 1980's. A student of archaeology at Wilfrid Laurier University in his spare time, his publications include statistical reconstructions of rule sets for Hnefatafl, and Viking Era pastimes.
Neil was one of the interpretive team at the 1996 presentation of the Norse Encampment at L'Anse aux Meadows NHSC for Parks Canada. He is one of the founding members of DARC and has been a cornerstone participant in all of the group's museum work. He also has designed and the Company's web site plus contributed a great deal of the written and image content. He exercises his project management skills as record keeper for the team's iron smelting experiments.
