Smelting iron from iron-sand is the oldest known method of iron production. As seen here - the effort required to make 10 or 20 pounds of iron is immense. I've long wondered how hard it would be to turn our local iron-sands into iron (or steel). Now I know :-(. Ours has high titanium content. The enthusiasm of the narrator and her evident joy over the hunks of metal that they produce is a delight to see. (She has an ornamental ironwork business and is a black smithing instructor at the related 'project') https://www.youtube.com/watch?v=3DeYga8cdUSnM C*lay & Steel:* https://www.clayandsteel.com/about https://www.youtube.com/channel/UCUFFRgPXg1cqcysYLsih9Pg https://www.facebook.com/clayandsteel/ *The Crucible, Oakland* https://www.thecrucible.org/ Wikipedia - https://wiki2.org/en/The_Crucible_(arts_education_center) Yelp - https://www.yelp.com/biz/the-crucible-oakland Facebook - https://www.facebook.com/thecrucible94607/ Images - https://www.google.com/search?q=3D%22the+crucible%22+oakland&tbm=3Disch&sou= rce=3Duniv&sa=3DX&ved=3D2ahUKEwjdjZWTsfXiAhUHVH0KHS5hDKMQsAR6BAgDEAE&biw=3D= 1440&bih=3D757 https://www.thecrucible.org/our-space/things-to-do/?gclid=3DCjwKCAjwuqfoBRA= EEiwAZErCsi4Lt__b1698SZdmaoc-_JM1mJY8kiw97hWZ_qZaTHZQkeTVVsM6rhoCqdUQAvD_Bw= E&gclsrc=3Daw.ds legion https://www.google.com/search?q=3D%22the+crucible%22+oakland&oq=3D%22the+cr= ucible%22+oakland&aqs=3Dchrome..69i57j0l5.9102j0j4&sourceid=3Dchrome&ie=3DU= TF-8 A web search on - "clay and steel" turned up a remarkable amount of material.
