materials and processes library

teachable library

"Materials and processes for people who design and make things."

Web only. No install, no account, no sign-in. Static site — every page is HTML on disk; the database is a JSON tree. Works offline once loaded.

Very, very early. ForMatter is 1 day old — the v0 seed shipped 2026-04-26 (63 entries) and the v0.5 buildout closed 2026-04-27 (176 entries, climbing — 119 materials, 36 processes, 21 applications across 14 categories). Everything is provisional: numbers are editorial estimates, voice blocks are still being added, the cabinet drawers don't all open yet. Verify any property, citation, or substitution against a primary source before designing against it.

I. What It Is

ForMatter is a local-first library of materials, processes, and applications, sized for an early product-design student to find what they need and a senior material-science student to really sit with. Same database, two registers, no subscription.

Half of teaching materials is teaching how the material is made into the thing. The standard subscription-paid reference was often 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.

We try to keep a balance between the matter, how the matter is given form, and what other people have done with these processes and materials.

II. Three Entities

Counts are a snapshot — every number below moves while you read this. The library is a baby; entries land daily.

Material

~176 entries today · 14 categories · climbing

What the thing is made of. Metals, polymers, woods, glass, ceramic, textile, composite, biomaterial, paper, smart, gemstone, other. Every entry carries a freshman tier, a technical tier, a sensorial paragraph, PBR starter values, citations, and links to the processes that work it.

Process

~36 entries today · 7 families · climbing

How the material becomes the thing. Subtractive, additive, formative, joining, finishing, treatment, hybrid. A peer entity, not a footnote — the same depth as a material, the same citation discipline, linked back to the materials it consumes and the applications it serves.

Application

~20 entries today · use-cases · climbing

What the thing IS, in the world. A bicycle frame, a chair, a water bottle, an architectural facade panel, a brooch. Each application links through to the materials and processes that build it, and to the substitutions worth knowing.

Form and matter, inseparable.

ForMatter Materials index — 119 entries across 14 categories, with category chips and per-finish facets, then the metal subset listed beneath — **Materials index.** Twelve category chips, three finish facets, then the entries themselves — name, NEW pill where applicable, one descriptive line that lands.

ForMatter Processes index — 36 entries grouped by family: subtractive, additive, formative, joining, finishing, treatment, hybrid — **Processes as peers.** Subtractive, additive, formative, joining, finishing, treatment, hybrid. Same depth as materials, same citation discipline.

ForMatter Applications index — 20 use-cases including bicycle frame, brooch, chair, consumer-electronics enclosure, desk lamp — **Applications.** Bicycle frame, chair, brooch, facade panel, enclosure. The classroom exercises plus the ones nobody usually catalogues.

ForMatter Project panel — saves to this browser only, no account, no cloud, with options to print as brief or clear project — **Project panel.** Open a material, process, or application and tap +project. Saved locally to the browser. Print as brief, or save the page as PDF for a permanent copy. No account.

III. The Choral Fugue

Every entry is built like a small choral fugue. The subject is the material — or the process, or the application — stated plainly. That's the freshman tier. The answer enters in technical register, with property tables and PBR starter values for the readers who render in 3D. The countersubjects come in from the linked processes, applications, and sustainability profile. Citations are the final stretto.

Where a real authored voice attaches to the material, a marked versal block sounds. The voice is named, dated, mode-tagged, and cited. It does not pretend to be the material's own voice. It knows it's a voice in the chorus.

The architecture: archival cabinet on the outside (browse, index pages, sphere wall, by-finish gallery, at-a-glance). Working bench inside the entries (dense, photographic, big property tables, the sensorial paragraph as italic block-quote). Shell carries the identity; the page does the work.

Today's distribution across the twelve categories — a snapshot, not a budget. Numbers move daily.

IV. Voices, Marked And Cited

Polyphony grows where the canon attaches. Nothing faked to fill empty staves. Voice rule, suite-wide: living authors are quoted only — verbatim or not at all. Dead authors may be channeled within their philosophy — marked as channeled, dated to the source work, never impersonated. Citations for everyone and everything.

Roland Barthes

channeled

On PMMA, and on injection molding — channeled within his philosophy of "Plastic," Mythologies, 1957. The block sounds when the material enters the chorus; the citation closes the stretto.

Sōetsu Yanagi

channeled

On white oak — channeled within his philosophy of The Beauty of Everyday Things, Penguin Modern Classics 2017. A craftsman's register; the wood as participant.

Walter Benjamin

channeled

On soda-lime glass — channeled within his philosophy of The Arcades Project, Belknap/Harvard 1999. The glass that shows you the city while showing you yourself.

Chris Lefteri

verbatim

On PLA — verbatim from Ingredients No. 2, September 2007, p. 5. Living author; the rule lets the quote in only as itself, not as a paraphrase, not as an imitation.

More voices arrive as the canon attaches — Untracht and McCreight on jewelry, Miodownik on acoustics. Each marked, each cited. Polyphony grows where the canon attaches. Nothing faked to fill empty staves.

V. Rules Of The House

Citations or it didn't happen. Every property number, every claim, every borrowed register has a traceable source. If the source isn't in the readings folder or independently verifiable, the citation doesn't ship.
Living authors are quoted only. Verbatim or not at all. No paraphrasing into a living author's voice. No invented Lefteri sentences.
Dead authors may be channeled within their philosophy. Marked as channeled, dated, cited, never impersonated. The block reads as a sympathetic continuation, never as a forgery.
Confidence labeled honestly. A senior's low-confidence-with-three-citations beats a freshman's high-confidence-with-none. The interface lets you filter to a confidence floor.
Local-first. Works offline. No login, no subscription, no telemetry. Saves stay in your browser; preferences too. Print as brief or save as PDF for a permanent copy.
Process is a peer. Same schema depth as material. Same citation rule. Same right to a voice block when the canon attaches.

ForMatter About panel — explaining what the library is, why it exists, and the rules of the house — **About panel.** Why this exists. What the wedge is. The rules of the house, stated plainly.

ForMatter Concordance panel — house vocabulary including anisotropic, application, BRDF, channeled, choral fugue, clearcoat — **Concordance.** House vocabulary. Every term ForMatter uses with intent — what it means here, how it differs from a generic reading. Anisotropic, BRDF, channeled, choral fugue, clearcoat.

VI. What It Is Not

Not a CAD database. The PBR starter values are starters; tune in your renderer.
Not a procurement tool. No SKUs, no live prices, no checkout flow.
Not a substitute for ASM, ASTM, ISO, or a primary supplier datasheet. Use those for any number you'd design against.
Not a subscription service. The library is on disk. The build emits static HTML. There is no server.
Not finished. v0.5 today. The number of entries climbs while you read it.
Not a teacher. Willing to be useful to one.

VII. A Research Note

ForMatter is a renato.design research artifact. Released as a teaching surface, not a service, not professional software, not a substitute for an engineer or a metallurgist. Every property in the library — modulus, density, embodied carbon, finish behavior — is an editorial claim about the world, as close to right as we can reasonably get it, and noted as editorial where it matters. Use your judgment. Verify anything load-bearing against a primary source.

Nothing leaves your browser. No analytics, no account, no server. Saved projects, preferences, last-seen entries — all live in localStorage under formatter:. Prefs → Reset clears all of it. Print as brief renders a one-page summary you can save as PDF; that PDF is the only copy that leaves the browser, and only if you ask for it.

Sibling of Plenum, Specimen, Ingenue, gesture, graf, and the Renato Rhino plug-ins. Part of the renato.design ecosystem — same voice rule, same citation discipline, same local-first stance.
