I want a forge that requires no blower, is made of dirt, burns
wood, and doubles as a pottery kiln. My first design was to make a rocket forge using the fire chamber dimensions in Ernie/Erica's design. I live in Florida and a sand forge would it good up so I dug a clay mine.
We excavated clay until we hit
water about six' deep.
Plan A: build the forge using E&E's design.
It failed for two reasons:I did not check dimensions often so it slumped and it was clay, not super-insulation. I didn't know the materials were a critical factor.
Plan B. Chip out the interior to specs.
Plan C. Rebuild.
Still wrong material. You can see a Chuck of the old forge.
I then learned that it needed insulation to work
Plan D. I found
this video and followed his design. This is my rendition.
