Hi.Hi Graham
Have a look at this and google for other information. We were well behind," a couple of centuries", really some other countries that had steel making technology well before it was done in the "developed countries". I was astonished to find out about this, and in a country that I had never heard of ??.
"Ancient Ferrous Metallurgy Sites of Burkina Faso
This property is composed of five elements located in different provinces of the country. It includes about fifteen standing, natural-draught furnaces, several other furnace structures, mines and traces of dwellings. Douroula, which dates back to the 8th century BCE, is the oldest evidence of the development of iron production found in Burkina Faso."

Perhaps it's origins are from the simple practice of fanning or blowing on a fire to increase it's intensity?............I can understand how glass could have been observed in the natural world with glass forming at the bottom of fires on a sand base, but where in nature does the beginnings of a blast furnace come from?
Cheers.

Thank you for being so diligent there David S. I am pedaling hard to flick this repair over to whoever has the hands to catch it but one way or the other we will get it sorted. At the present moment I am unable to do any casting but if it can wait a while we'll get it sorted somehow. We Renault people are like that.So M. Fregate, here's a possible casting project for you ...
Fregate parts wanted for restoration job
A friend needs a key alloy casting that holds the pedal cluster shaft AND the brake master cylinder. Some other parts needed too, so basically we are trying to find a car that won't be restored with an owner willing to make it near-impossible to fix later! Does anyone know of a parts-Fregate...www.aussiefrogs.com
Maybe there were a few more active volcanoes in the 8th century BC to be observed.Hi.
Yes I can understand that aspect, but where did the idea come to combine the fuel, ore and flux, and know to heat it to very high temperatures?
Cheers.
There are several definitions of "easy". Good you've taken such good photos. Please put my name down for the book when it is released.Vintage piston making for the home hack.
Of course it is well within the realm of possibility that a home-hack sand caster can find ways to make pistons, I know this because I worked it out a while back. This was all about the exercise rather than the end result and no particular alloy was used, just some leftovers from the bin. If I were to ever have the need to get serious about making a piston I would make some changes to the process, but it is eminently doable at home.
Follow the steps kids, it's easy.
