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

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
