|ABSTRACT : A Training Course in Iron Smelting,
using a small scale bloomery furnace. Artisan Blacksmith
Darrell Markewitz offers a regular series of weekend long
programs in a number of aspects of traditional
Blacksmithing. Special courses include : layered steels
(pattern welding), bladesmithing / knife making, bronze
casting, iron smelting. Programs held at the Wareham Forge
in Ontario Canada, with remote teaching offered at other
Potentially this program will be offered in
Expect a Mid Summer to Early Fall date
Your instructor, Darrell Markewitz, is well known
as a specialist in the Viking Age. He consulted on the
Smithsonian's 'Vikings - North Atlantic Saga' and the
Newfoundland Museum's 'Full Circle - First Contact'. He
designed and produced the exhibit 'World of the Norse' for
the Cranbrook Institute of Science and the 'Norse
Encampment' living history program for Parks Canada. In
2001, he was part of a special research team at L'Anse aux
Meadows NHSC working on presenting Viking Age iron
smelting at the site. Since then he has lead a series of experimental iron
smelts, attempting to discover lost techniques as
they might have been used by the Norse undertaken by the Dark Ages
Re-creation Company. He is one of the core group of
demonstrators and team leaders behind the highly
successful 'Early Iron Symposium' - an annual event held
at the Farmers Museum in Cooperstown NY. He continues to
research, experiment into specifically 'Pre-Medieval'
bloomery furnaces. As well as providing academic papers,
he has worked on projects in Canada, the USA, the UK and
Introduction to Smelting Iron is an intensive hands on program, roughly 18 hours in duration. Students will prepare materials, build a smelter, then fire it to produce a workable iron bloom. A bloom weighing roughly 3 - 5 kg is expected from use of about 30 kg of ore.
This program does not require any previous metalworking experience.
Programs are open to any physically able
people, from young adults onwards. (Aged 16 an up -
see a special note : Teens as
Students). Any students with
"learning \ physical disabilities" need to refer to the
detail section on Course
Requirements. English is the language of
instruction. Sorry - the Wareham Forge is not really
wheel chair accessible.

Saturday, the program starts with a background lecture covering the historical development and the practical elements of the small direct process bloomery furnace. The balance of the day will be spent constructing the 'Norse short shaft' clay smelter itself. The smelt normally requires about 80 - 100 KG of charcoal to be smashed to size and sorted. Ore will be prepared, with various potential types being evaluated. At least some rock based ore will be roasted and crushed for the experience. Other furnace types will be examined (as part of ongoing experiments at Wareham). The working site will be prepared for the smelt the following day.
|A LONG day Sunday will start at 9 AM with the pre-heating the furnace. Any more charcoal required will be prepared. The initial charge of charcoal is scheduled for roughly 11 am. The actual process of the smelt takes roughly 6 - 7 more hours. Participants will learn the effective managing of an operating smelter, including adding fuel and ore, controlling air flow, and taping slags. Valuable experience will be gained in how to interpret the sounds of a correctly operating furnace.||
Cutting the Bloom
|After this, the resulting iron bloom will be extracted
from the furnace - while the mass is still white hot!. It
then is given a primary consolidation, compacting the
surface using sledge hammers. The iron produced will be
cut to sections and shared between the participants.
This program does not require any previous metalworking experience, and is of interest to students of history as well as blacksmiths.
|The course fee includes a handout on disk - and a portion of the bloom created. Students should bring a simple lunches - and 'hand meal' dinner Sunday (something that can be grabbed while managing the smelt!). There will be a handout provided with and overview of technique, equipment and material sources. All required safety equipment will be provided. Students are recommended to wear old clothes, which must be all natural fabrics (cotton ideal) and work boots. A long sleeved shirt and cap is recommended.|
