Actually that again is incorrect.
You're confusing Cold Cast Porcelain with Polyresin.
Polystone is, yes, Stone additive mixed with Polythalene, not urathane. Polythalene is the most common of all the plastics and cheaper usually. The Stone additives in Polystone are not Porcelain, it's usually harder materials or depending upon how cheap the manufacture wants to be they can even use plaster.
Polyresin is basically the same thing, the difference is that Polystone has more stone additive and polyresin has more plastic resin.
Cold Cast Porcelain is Polyurathane mixed with porcelain powder, hence the name. All three are cold cast but mixed differently with different additives.
That's why they call all three something different, and not an AKA. Anyone who tries to sell you something different is probably ripping you off on materials.
The term "Cold cast porcelain" was used for all resin and stone compounds back in the 90's and up to the mid 2000's by almost every single collectible company regardless of its grade, quality and element composition. In recent years we started to use the term "polystone" for almost all new statues in the market. The truth is that there are different levels of mixture, different additives (as you mentioned) therefore the quality differs from piece to piece and from company to company. This is why some statues feel sturdier than others and better made.
I understand your points. I am not a chemical engineer (like my father) but I understand basic chemistry.
