A mold-side texture that mimics fine sandcasting or sandstone — irregular, slightly directional, soft. Reads as suggestive of cast aluminum or as cast bronze, even when the part is injection-molded ABS. Studio-design plastic that wants to read 'cast not molded.'
Photochemical / laser-etched mold cavity in the sand family — Mold-Tech MT-11020 sand variant (Ra 8–14 µm), VDI 3400 plates 36–40. Distinguishes from leather grain (which has a regular pebble pattern) by the irregular, slightly fractal sand-like distribution. Common on consumer-product housings going for a cast-metal look — speakers, cookware handles, faux-bronze hardware. Pairs with the textured plastics injection-molding process (proc_injection_molding_textured_grain) and with matte resin formulations.
character — irregular sand-like texture, slightly directional, evokes cast metal even on plastic.

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.
