Crap! I wasn't getting notifications.. because the FIRST one got buried.. and theen.... I plumb forgot... So what
@Japonicus said is ACTUALLY quite accurate.

Ok.
What I was going to say, is, I've been enamored by these pots, even before I started ceramics.. with the implied (or not) column-esque entities/facets of the design.. matching (or not) the skirts and accentuated Rims. And when feet are involved.. oof! SO elegant, but STURDY-looking... Beautiful designs, Impressions.. throughout.
My FAVORITES are ones that somewhat resemble that same "Poor, cement-esquel construction.. but appear to have Cambodian brick work.

..Those ones DREW me to the design... the standard, cement-block style.. it's just THE BEST, in my opinion.
Buuuuut. I DID run across some Pretty sweet "Gaudy", dang near "over-the-top" ones recently that I actually quite enjoyed... let me try to find the video.
There's a mix.. but it's MOSTLY that "gaudy" stuff!
Aaaanyways...
From a tad of experimentation over my pottery dive.. and seeing several videos of pottery villages and observing their varying methods. Reading a few articles on Vietnamese specific glazing and moulding.. (Korean, too).. It seems to me, that, If using CLAY.. I'd have to construct stamps (as well as an apparatus to steadily HOLD and steady stamps) OR construct circular walls of depressed mold.. and press it in. (there's DEFINITELY a name for this..) OOOR do the Moulding separately... If I was to partake on such a build.
Concrete Seems easier..
But now. I'm second guessing my reluctance.
