The shiniest a metal gets without plating. Worked through finer and finer abrasives until the surface scatters no light — you see your face in it. The bezel of a stainless watch, the inside of a polished silver bowl, the show side of a chromed motorcycle tank.
Mechanical surface reduction across a sequence of abrasives — typically 320 → 600 → 800 → 1200 grit silicon carbide, then loose abrasive on cloth or felt buffs (tripoli, then rouge or diamond paste 6 → 3 → 1 → 0.25 µm). Achieved Ra ≤ 0.025 µm (≤ 1 µin). Vulnerable to fingerprints and micro-scratching; usually clear-coated or used on stainless / precious metals where light marring polishes out.
character — specular, cool, slick, shows every fingerprint, optical-grade reflective.
But its standards were disastrously imperfect, inaccurate, and wrong.

House vocabulary — terms ForMatter uses with intent.
Materials and processes for people who design and make things.
A local-first library of materials, processes, applications, and finishes — equal weight, citable everywhere, so a student can move from "what is this" toward "what's actually buildable here, now, by me." Part of the renato.design ecosystem — sibling of Plenum, Specimen, Ingenue, gesture, graf, and the Renato Rhino plug-ins. Form and matter, inseparable.
Half of teaching materials is teaching how the material is made into the thing. The standard subscription library was always light on that half. The wedge here isn't better samples or a prettier interface — it's treating Process as a peer entity, not a footnote.
