An oil-and-varnish blend that soaks into wood and cures in place, leaving a thin, low-sheen film. Brings out the figure without the plastic look of a thick varnish. Mid-century furniture, kitchen tool handles, the cabinetry on a small boat, the inside of a guitar.
Blend of drying oils (linseed, tung) thinned with mineral spirits and a small fraction of long-oil varnish (alkyd or phenolic). Drying oil cures by oxidation: the oil polymerizes via O₂ uptake into a soft solid film. Multiple coats wiped on, excess wiped off after 15–30 min, between-coat sanding with 320–400 grit. 3–6 coats build to a satin sheen; final film thickness ~10–25 µm — much less than surface varnish. Penetrating not surface-building, so dings rub rather than chip. Re-finishable in place — flood, wipe, recoat.
character — low satin sheen, deepens grain warmth, refinishable, ages with use.

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.
