The primary difference is that "Venetian plaster" process is specifically intended to mimic the look of marble or stone and so the method doesn't really veer too far outside of that for materials or process.
These kind of artists seem to only use quartz or other "smooth" acrylic plasters and pigments that don't have the same structure and are generally thin and temporary (less than 20 years expected age) - so not limestone the same kind of lime aggregates like tadelakt which is what I use.
I'm attempting to make something that can last 2000+ years - somewhere between an oil painting and a marble sculpture.
Very interesting idea. So if I understand it can take abuse, pieces could be ground right off and you would have a different texture but the color would remain, unlike basically anything else where it would revert to the base material color.
I’m not quite sure what you have in mind but it’s not really abusable, it just won’t deteriorate as quickly as other types of painting.
If you cut into it then you may or may not get different colors depending on where you slice. In that sense it’s not much different mechanically than oils, just with way more depth.
