don't need water proofing afterwards

and the stone wall becomes like 1 stone piece afterwards

Never though of welding granite though

ever see those stones that look like they're perfectly cut into a wall, but they're several thousands of yrs old

Now we just need a robotic applicatiin technique

Yes

Inca

same principle

Aztec

Older

Olmec

some of them stones....are slag formed

in ingots

Yea butnit looked like they put softened stone and let it harden thats what i think they did

thats what lava is ....it's slag from the earth

Makes sense

So you could just use a form

Use some kjnd of dust for the medium

could, but would need a hell of alot better source of heat

Like granite dust in your case

Yea like lets just get a lava tap and hook it up to the magma

diamond dust works best as a medium for ingot ..cools down fast...highest heat conductor

diamond and emerals and some rubies line the walls of lava tubes

Too expensive

so anywhere a volcano erupted....the dust around the main hole is layered in dirt, stone and gemstones

Seems like foamcrete would work fine

Crust
