I want to add a couple of afterthoughts....
As for the base of the pyramids being cut stone, that's very possible. Now everyone seems to wonder how they managed to lift the stones progressively
higher but I want to posit this....
Stones were cleft and put in place for the first "level". Once those were in place, local sand / dirt / whatever you want to call it was piled up
against one wall forming a ramp of sorts to allow stone to be lifted to the next level. As the pyramid(s) grew higher, the ramp was added to in height
and width as well as length in order to maintain a constant grade from the level being worked to 'ground level'. As the pyramid grew taller, it
would require exponentially more sand or dirt to create the ramp and at that point, construction turned from cut stone to 'pour in place' blocks.
Not sure how many here are familiar with trenching and the like, and sorry for derailing a moment but.... Generally, when trenching, you do not apply
any significant load to ground on the side of the trench unless the load is as far from the trench as the trench is deep in order to avoid cave-ins-
basically at a 45 degree angle. So, to be safe, a 1 meter deep trench requires no load be applied to the surrounding dirt within 1 meter of the edge
or the risk of cave-in increases. The same would apply to the ramp. If the ramp were 40 meters tall, the ramp's sides would extend out approximately
40 meters, probably more actually since made of sand, so that the ramp 'road bed' itself wouldn't slough off. Make sense? Anyhow, back on
The large number of people required to move the cut stone would shift from moving blocks to moving smaller quantities- perhaps 5 gallons or so- of
slurry / concrete / whatever you want to call it, and to building and relocating forms. Since their 'crete' wouldn't "go off" as quickly as
modern concrete, delays in pouring mixes into the forms wouldn't result in the blemishes we get today when we try to pour new concrete next to older
concrete. Plus, since they are pulling it all from a common, perpetual mix, changes in composition would be minimal resulting in an overall consistant
Then remove the sand ramp from around the pyramid and voila, a pyramid.
Now back to the pots:
Make a central mold (the void of the pot) out of basic materials such as sand, dung and water (similar to adobe) then put that upside-down on a
surface. Make the body out of the "Egyptian concrete" and let it set up to the point it is 'clay like' but still workable and can be molded around
the central mold. Once that's done, apply another layer of 'adobe' around it, put it in the furnace and fire it... or don't- just let it cure
naturally. Once it's hardened, remove the outer molding and the inner molding- shouldn't be too difficult to wash off some mud, should it? And
you're left with a concrete vase, bottle, whatever. A little finish work on it and 'poof' ancient pre-cast concrete pottery. If you're really
good, you could probably line the inner section of the cast with lambskin, sheep stomach or something, to keep the 'crete from affecting /
interacting with it thus requiring little to no work on the inside of the vessel.
