I have always wanted to make my own hammer from ore...
most probably this will be refined and carburised (some not) and made into seax , I have a big store of samples from past smelts to mix and match different carbon levels all the way from wrought iron to cast iron
all the best Owen

The pancake piece in the photos weighs 11kgs and is about 12" diameter by 1 1/2" thick. We did not have anytime to cut it up but it will be very solid now its had a go under the 200cwt hammer.
To give you an idea of the product, here are some photos from a smelt we did in April last year. This time we let the bloom cool down and then cut it up.
This bloom weighs 18kgs

First several years were had very small outputs but got to getting good 15 pound blooms on a regular basis towards the end. Ore makes a big difference with magnetite being a dream to smelt compared to taconite---which is even worse than goethite!
Our rituals always included cooking steaks and sausages over the furnace as well as singing and telling tales---6+ hours feeding the furnace you need some entertainment!
I really envy you that bloom consolidator!
And slag has a very good use if you have swampy bits in your driveway or garden path...

You are right we did break up the stack. This was to get the bloom out. We did try to wiggle the bloom out and keep the stack but this is about the 3rd or 4th smelt using this stack so we decided that it would be best to build another one for the next time.
Here is the stack before we started to patch it up,
This photo shows a glass over the air pipe so we can see how hot it is running and also see when its getting blocked up or the level of the slag is up to the tuyere,

Now, I've got access to magnetite, but not for free since I don't work at the ore refinery anymore.
I would like to try this with bog ore at some point, but in the area there's also a ready supply of pyrite from the scrap piles of various mines.
I'm thinking it would be less cost and work to try with roasted pyrite first, are there any objections?
