Part of what I'm investigating here is not bronze, per se, but something we can use in lots of materials. Back in 2008, a new participant appeared in the Node Cult and gave the first usable curvature detector. (as matmatic script - nodes are overwhelming here)

Subsequently, runtimedna decided to "improve" their forum software (much like here) and they ruined that thread. Links are gone - text disappeared. (That is why I somewhat abandoned RDNA - now I'm doing the same here - where will I go? At Daz the users think my math is offensive.) Anyway it's hard to decipher the thread. But I'm trying to resurrect that thread because one of the common effects here is that on convex curves, the brass is polished by rubbing. On concave curves, the brass is dull from lack of contact and the easier buildup of verdigris and environmental crud (dust).
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
