About This Video:
I smelted iron bacteria in a short furnace and produced a small quantity of iron prills (small iron spheres). In my ongoing quest to reach the iron age, further experiments were conducted concerning furnace design and the treatment of ore. I began by making a very short furnace. A pit 25 cm wide and 25 cm deep was dug and the tuyere of the forge blower placed in a 15 degree downward angle into the pit. Onto this, a furnace stack made of mud and grass was built 25 cm above ground level. The furnace was fired at various stages to help dry it. It took less than a day to build.
Eucalyptus wood was collected dead off the ground and stacked into a re-useable charcoal mound I had made previously. The top was sealed with mud and the mound lit. It took about 2 hours 30 minutes for fire to reach the air entries, at which time the holes were sealed and the top closed with mud.
Iron bacteria from the creek was gathered and brought to the smelting hut for processing. Charcoal was ground into a powder and mixed with the ore and water in the proportions of 1:1 char to ore by volume. This mixture was formed into 59 pellets 2.5 cm in diameter and then dried on top of the furnace.
To make the smelt, a wood fire was made in the furnace and allowed to burn for about an hour by natural draft and blowing. When the wood burnt down to the tuyere the furnace was filled with charcoal and 10 pellets were added to the top and the blower was engaged. Three handfuls of charcoal and 10 pellets were added at about 7 minute intervals totaling about 42 minutes. Charcoal was then continuously added after the last charge until the basket was empty. It took a total of about 3 hours working the blower until the operation ended.
The mass of slag and iron prills was prized out of the furnace using a log and wooden tongs. It was hammered flat while hot but no large bloom was made. Instead many small iron prills were found. These mostly seemed to be cast iron.
So far this is the largest amount of iron I"ve made in the wild and it used less charcoal than previous attempts, so I consider it a success of sorts. The ore must be mixed with carbon to ensure the correct reduction chemistry normally provided by carbon monoxide in a taller bloomery furnace. The fact that cast iron was produced suggests that next time less charcoal powder be added to the ore pellets or perhaps none at all considering that dead iron bacteria may also contribute some carbon to the ore. Alternatively, cast iron can be re-melted in a "finery" furnace, a small highly oxidizing furnace, to remove excess carbon, producing steel or iron. Alternatively cast iron can be converted into malleable cast iron by heating it in an enclosed container at 800-1000 c for long periods. Further experiments will be conducted.
About Primitive Technology:
Primitive technology is a hobby where you build things in the wild completely from scratch using no modern tools or materials. These are the strict rules: If you want a fire, use a fire stick - An axe, pick up a stone and shape it - A hut, build one from trees, mud, rocks etc. The challenge is seeing how far you can go without utilizing modern technology. I do not live in the wild, but enjoy building shelter, tools, and more, only utilizing natural materials. To find specific videos, visit my playlist tab for building videos focused on pyrotechnology, shelter, weapons, food & agriculture, tools & machines, and weaving & fiber.

Assembling blower A bark fiber string is simply used to drive the impeller in a reciprocating manner Tuyere is put in place 25 cm wide, 25 cm deep pit is dug Lined with mud Mud and grass Building a stack to a height of 25 cm above ground Fire to help dry it Finished furnace.
Stacking charcoal mound with Eucalyptus wood Sealing top with mud Lighting mound Fire burns back down into the mound against the draft Volatiles exit the top while the wood converts to charcoal When fire reaches the air entries, it's time to seal them with mud to prevent the newly made charcoal from burning After a 2 hours and 30 minutes the top is sealed and the mound left to cool overnight The next day the mound is opened and the charcoal is collected Partially burnt timber is tossed aside to be reused in the mound next time.
Dry mud is returned to the pit to be used next time Useable charcoal is put into the basket Charcoal is stored in the smelters hut out of the weather Ordinary creek on land with normal iron levels Ordinary iron bacteria (found on all continents) concentrate iron from the water table Collecting iron bacteria Add to storage pot Crushing some charcoal to powder 1:1 ratio by volume of ore to charcoal.
Mix with water Form into 2.5 cm diameter pellets Dry on furnace Wood preheat for 30 minutes Fill with charcoal Add 10 pellets Begin blowing furnace 3 hand fulls of charcoal every 7 minutes or so 10 more pellets.
More blowing Final charge added Whole process took about 3 hours of blowing Extraction procedure Hammering slag flat to hopefully flatten iron Mostly slag But quite a few prills (small spheres) of iron These are larger and more abundant than the yields of previous attempts I've made See how the prills form on the surface of the slag. Microscopic pieces of solid/liquid iron must join together as the molten slag flows.
More prills Separating iron prills from slag These prills are mainly cast iron or steel due to the high carbon content of the initial ore pellets. Less char powder should be added in future Iron prills and slag

It's largely forged-iron attributable to I added too valuable charcoal powder. Old attempts (at dwelling, no longer within the wild) yielded malleable iron that will likely be hammered flat. I believed that this form of quick furnace would be too oxidizing then all once more it turns out enough. Any iron smelters with out a doubt be happy to inquire of of questions/ offer advice voice. Thanks.
Right here’s inaccurate. I do know he didn't develop that camera out of grime and sticks. What, did he lower down a microchip tree? Come by sincere, dude.
3 years later, and we in the end purchased a knife
Like this video this asmr 😩😩😩😩
Daring to be doing blacksmithing barefoot
Thanks
yo what set of cargo shorts are those? higher than propper ?
