Mud Bubbles

I had to go all the way back to post #1 to find the reference.

I have my own design, of course. It has a general leveling (see the cut-and-fill that Geoships did). But then to mimic historical precedents it has a fire ring in the center, in a sunken conversation pit.

Except this fire ring would be a smokeless fire pit..

The two step pit would have a sump underneath and an air tube that spirals in from the outside. When the fire pit is not in use, it can be a fan-driven earth-tempering air intake.

Any arbitrary soil sample will need amendments, usually clay or sand. A rammed earth floor can be stabilized with ox blood or rice water. Upper floor levels would be shoes off, burnished hard wood.

Oxblood? Ummm that's a programmer's insider joke.

The issue I see with ceramics is that they tend to be brittle and don't like movement. Not a candidate in the west. However depending on definition, bricks are ceramic and if one used a RTV you could get ceramic "bricks" to work well

It was the practice in Medieval times, when oxen were more common. Can't find a reference.

Technically, it's a geopolymer. The Geoship CEO, Morgan Bierschenk, describes it as similar to bone. It cured at room temperature, in from 45 down to 3 minutes, depending on how hot the mix is.
