By the fourteen hundreds they had blast furnaces that totally took over for these and rendered them completely antiquated.

This must have been one of the most shitty jobs ever. But at the same time, you look absolutely badass doing it. There’s something about dragging a ball of flaming metal around and then proceeding to beat the shit out of it with a hammer that commands respect.

Excellent work. Understanding how much work this is/was makes you appreciate modern furnaces, blowers, and power hammers more. A lot of blood, burns, and sweat goes into a smelt.

I’ve always wondered how they got furnaces hot enough to melt Metal back then . This is so cool

Great job!, thank you all for showing how hard is to get metal. 👍👍🙏

I have to say, this is ideal as opposed to an automatic blower. You have so much more control over the amount of airflow at any given time. I was just watching another video in which the blower was so strong it was blowing their ore and charcoal right out the top. It's just more work.

It also seems to be a good idea to have two bellows to work in parallel, as in this video. Then one of the bellow is still blowing while the other one is restoring, maintaning a constant flow of air :)

Besides trapping, the American fur trade, which resulted in many of America's great trails being blazed, was carried on the back of steel. Native Americans would trade many pelts for steel in the form of knives initially and later hammers and raw stock. Very interesting stuff. I was in a village in India about 17 years ago and my mother thought to bring them some mirrors. I remember us giving out these tiny 6x6 mirrors and they were stoked! Apparently, they only had one in the village and it in the bathroom of a government building. People rarely had access to it. It's so easy to take for granted the technological, industrial and logistical apatatus that makes mirrors (something once highly prized) something disposable. Amazin.

The carbon content in the iron bloom depends on the temperature in the furnace and the charcoal/ore charging ratio. Usually, it is rather low carbon content. Low carbon, soft iron this is result what we want to get.

the goal of this experiment is to get low carbon alloy. I carburize it in different process. To get high carbon bloom directly in the furnace, the ore/charcoal ratio must be changed, more charcoal less ore. The hard wood charcoal gives usually better bloom carburize.
