I don't know the exact mix of clay/silt/sand. It was very clay-like.

The earth is loaded into the top of a big hopper with a bucket loader that has sort of a flail on the front of it. The flail sort of scrapes and flings the dirt into the bucket, and then the operator dumps that into the brick machine hopper.

The earth going into the machine is at whatever moisture content it was at when the operator picked it up ten seconds before.

I believe that they were letting the bricks cure for some amount of time, but I don't think it was long, maybe just a day or two.

In this case the earth bricks are going onto a concrete slab, so they have a solid foundation. When finished, they will be covered with a lime wash.
