A high-shine produced not by removing material but by deforming the surface — a hard polished tool (agate stone, polished steel rod, hematite, bone) rubbed against soft metal compacts the high points into the low ones. The bright surface on water-gilded leaf, the polished bezel on a hand-set silver bowl, ancient burnished black-pottery (Greek terra sigillata).
Cold plastic deformation polishing — a tool harder than the workpiece, with a smooth polished face, rubbed under controlled pressure across the surface. No abrasive, no material removal: the asperities flow downward into the valleys. Surface roughness drops by an order of magnitude (Ra 0.4 → 0.04 µm typical). Cold-work hardens the surface (~10–20% Vickers increase on silver / gold). Burnishing tools: agate stones (water-gilding standard since the medieval period), polished hematite, polished steel rods (modern jewelry workshop), wood tools (terra sigillata burnishing in pottery). Distinct from compound polish — compound polish abrades; burnishing compacts.
character — high specular shine without material removal, work-hardened surface, traditional craft register.

Materials and processes for people who design and make things.
A local-first library of materials, processes, applications, and finishes — equal weight, citable everywhere, with cost-over-volume curves, trade-off profiles, equipment-tier filters, and second-life paths layered onto the data 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.
