I've built and fired a bloomery with success on the first run; it
required a lot of research, sweat, interpolation, and luck.
I posted this a year or so ago. However, the photos are no longer
online. I'm a volunteer at Red Top Mountain State Park in Georgia, a
past iron producing region.
We have run the bloomery several times since, with mixed results.
Mainly because I insist upon experimentation. Tuyere height, air flow,
"limestone, or not" , charcoal size, ETC.
One of these days I'll post a "Thesis" on How to Smelt Iron, From Ore.
For now, the only pic online is here:
Click on Photo gallery, then "Scenes at Red Top".
And yes, a puddling reverb would be a hoot to try to replicate
I welcome questions or comments
