A thick, opaque, mostly-feldspar glaze fired to stoneware temperatures in reduction. Reads as creamy white with orange / red 'fire color' where the body shows through and where carbon trapping happens. The signature glaze of Mino-ware tea bowls, Japanese 16th-century onward. Crawls and pinholes are part of the character.
Glaze chemistry roughly 80% feldspar / 20% kaolin / minimal silica or flux additions — the simplest glaze recipe in the Japanese tradition. Fired to cone 9–11 (~1280–1300 °C) in heavy reduction. Carbon trapping (incomplete combustion of the reduction atmosphere produces free carbon that the glaze captures) gives the characteristic gray streaks and the 'hi-iro' fire-color flashing on the body. Modern American shino (Malcolm Davis, c. 1980s) added soda ash for more pronounced carbon trapping. Surface character: thick, slightly crawled, often pinholed — defects in industrial pottery, signatures in tea-ceremony work.
character — creamy white with orange fire-flashing, thick crawled surface, tea-ceremony 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.
