Carbon deposited by PVD as a deep-black, low-friction, near-diamond-hard film. Reads as the modern matte black — knife blades, watch cases, gun barrels, fishing reels, firearms. Beats anodize and powder coat for hardness and wear; expensive but lasts.
Plasma-enhanced CVD or filtered cathodic-arc deposition of amorphous carbon with substantial sp³ bonding (tetrahedral amorphous carbon, ta-C). Film thickness 1–4 µm, hardness 3000–8000 HV (approaching natural diamond at 10000 HV), coefficient of friction 0.05–0.15 dry. Color characteristic deep matte black with slight silver-gray cast in oblique light. Substrate prep critical — film replicates substrate roughness; mirror-polished substrate yields smooth black, bead-blasted substrate yields satin black. Service temperature limit ~350 °C (oxidation onset). Standard finish on premium kitchen knives, sport-watch cases, firearm slides, racing-bicycle drivetrains.
character — deep matte black, low-friction slick, hard wearing, modern-tech register.

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.
