My first smelt attempt (partial success!)

Recommended Posts

First off, hello! This is my first post here--I've been lurking for months, reading the archives and enjoying how much knowledge everyone has shared. I appreciate what you've all built here.

Last week I smelted iron for the first time. I'm a medieval technology historian, and my book-research specializes in early medieval English iron bladesmithing. I'm also a novice bladesmith, and I've always wanted to smelt my own iron, since I saw Darrell Markewitz give a demo at the Kalamazoo ICMS in 2013. I drove up to Mark Green's place in December, and he walked me through the process. I was excited to build my first stack and try for myself.

And I made metal!

Unfortunately, my tuyere melted part way though (I used a ceramic kiln shelf support, and it didn't make it). I think this is what caused most of the slag in my stack to freeze up. I still got 4lb of iron (as well as a bucket full of iron-heavy slag for resmelting later), so I'm pleased for a first attempt.

I've got a copper pipe on the way for next time, and I'm hoping I can achieve a solid bloom on try #2 next weekend.

So far, the iron is forging up well!

Here are two blog posts with some more photos and a discussion of the equipment I used, if anyone's interested:

Thank you to everyone here for sharing so much knowledge. You helped me avoid a lot of newbie mistakes :)

Welcome aboard!  Very nice return for your first smelt, too.  Of course, having Mark to help advise is worth its weight in ore. B)  Looks like you got a little cast in that pic on the stump.  All of which reminds me, one of these days I have 50 lbs of nasty, quartz-filled high-phosphorus ore to smelt...

"Looks like you got a little cast in that pic on the stump."

I did, yes (600g when I sorted it, and 1840g low-carbon iron). I found most of the cast down in the bottom when I tidied up. I've added it to the "once I make enough to decarb in an Evenstad hearth" pile.

Awesome! Thanks for the links too. Nice documentation on the process and failure points. Like Alan, I too have 50 pounds of ore waiting. It's magnetically screened and sifted Arizona black sand. There's also about 160 pounds of charcoal in closed bins, and about 100 fire bricks waiting. I need to quit my day job.........:(

Can you expand on that ore recipe from DARC, or provide a link to it?

The steel I made in this smelt has worked up very nicely.

(The welded-on edge of the longest blade is hearth steel I made from scrap metal from the shop floor—everything else is bloomery steel from this smelt).

Here are three of them!

Horn handles, as per the early Anglo-Saxon period originals on which they're based.
