Canadian IRON Symposium
September 4 - 7 (Labour Day)
Sanctuary Armoury - outside Peterborough ON
https://www.warehamforge.ca/Canadian-Iron/index.html
The focus on this event will be on ORES.
Participants will construct a proven 'short shaft' bloomery iron furnace, but each team will work with a different iron ore type. This will include natural source, commercially prepared and analog ores. Each team will be provided with at least 25 kg of their ore (in some cases additional will be available). Each type has it's own wrinkles towards creation of the best possible bloom.
'Lexington Brown' Goethite - Bratton's Run Virginia
This is an ancient Fe2O3 rock ore, used for the pioneering work by Lee Sauder and Skip Williams. The reported elemental iron concentration is in the range of 59%. The material on hand was gathered by myself at the abandoned Bratton's Run Colonial era mine, so the quality should be considered random and lower. There is a quantity on hand that has been both roasted and broken for size. Although there is more than enough of the raw stones available to support two more smelts, these will need to be roasted and broken still.
DARC Red Analog - Pottery Supply
This is the standard Fe2O3 analog for Bog Iron Ore, used for the bulk of the experiments at the Wareham Forge. In the form provided, the elemental iron concentration is roughly 54%. The fine 'Spanish Red' powder, available from pottery suppliers, is mixed wet with 10% flour as a binder, then dried into lumps ready for the furnace.
This is an alternate analog, made from Fe3O4, again tested in our smelts. As mixed, the elemental iron content is roughly 60% (an excellent ore). Another fine powder, mixed with flour binder. Also available at pottery suppliers, this oxide is considerably cheaper (now) that the red.
Granular Hematite - Opa Minerals
This material is ground down from hematite ore from Quebec into very fine particles, and is sold as a sand blasting grit. An extremely pure Fe3O4, with an elemental iron content of 69%. The lack of silica combined with small particle size can make this ore tricky within these furnaces, without care to air / burn rate / temperature, cast iron can be created. With the addition of some additional sand for slag, this ore is most likely to produce higher carbon iron.
Individuals wishing to bring their own local ores for test smelting are more than welcome to do so! Be aware however, that each ore can rely on variations on furnace set up and method for best results. Any ore without at least 50% elemental iron content is unlikely to produce much by way of a workable iron bloom. At least 20 kg of a good quality ore is required.
