The presence of the slag is necessary for the bloomery iron process. Running the bloom (refined ones) the second time in the bloomery furnace can cause the burning of the iron because the bloom would not be protected by the slag. The Aristotle furnace is the better solution to get carburized.
This is great. Do you have any videos of turning wrought iron, blooms or mild steel into a high carbon fire steel or spark steel for flint and steel fire lighting?
Awesome video! Thank you for sharing. I've got a question - what role do iron gromps play in this process? Could you load the furnace with only charcoal and iron bars? How long does the process take?
You want cold air though, not hot. Sort of counter-intuitive, but cold air is denser, therefore has more oxygen per unit of volume. That’s what an intercooler on an engine is for.
Very nice! Love the sparks, where did you get your ore? I would love to travel to different countries and experiment with different ores and see which one i like best.
In my smelting experiments, I use different types of ore (bog ore, siderite, hematite, and magnetite). In Poland, the most common is bog ore but siderite and hematite also can be found.
Nice Furnace, but why go through all the trouble to manual/traditionally make it if you going to refine it using modern means, seems like a strange duality.
The whole idea is to learn more about how certain processes were carried out by our forebears, the distinct process in this case, being the Aristotle furnace. Whether the bloom it is then struck by a power hammer or a striker with a sledge makes no real difference to the steel, but saves a great deal of time and effort ...... unless you prefer to watch a very much longer video .... ?
Just saw this on facebook. Good to see more bloomery related items on UA-cam!
Thank you for sharing! I’ve wondered about putting a bloom back into a new furnace and running it again to clean out more slag and to add more carbon

bloomery iron gromps are conglomerate iron and slag. A small amount of slag gives better results. You can use slack instead gromps.
Did you use iron you made yourself? What's the composition of the steel you got? C%?
Yes i used my own made iron. The alloy has about 1% of C.
@@officinaferraria cool.
I don't think it would have taken them more than 10 minutes to realize they could heat the incoming air between the bellows and furnace.
