Stone ground and polished through the full diamond-pad sequence to a mirror gloss — the surface that brings out the stone's full color and depth. The wet look. Carrara marble countertops, granite kitchen islands, the polished face of a lobby column.
Diamond polishing sequence 50 / 100 / 200 / 400 / 800 / 1500 / 3000 grit resin-bonded pads, then optional buff with cerium-oxide or tin-oxide compound on felt. Surface roughness Ra ≤ 0.1 µm. The polish brings out chroma — water-drop test: if a drop beads and looks shiny on the surface, the polish is complete. Vulnerable to acid etching on calcareous stones (marble, limestone, travertine — citrus, vinegar, wine all etch the polish away). Granite and quartzite are silica-bound and acid-resistant. Modern stone-care formulations include penetrating sealers (siloxane or fluoropolymer) to delay water and stain absorption without changing the surface look.
character — wet-look mirror, deep chroma, shows pattern fully, vulnerable on calcareous stone.

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.
