About this site

Dye & Chemistry records how dyeing works as claims with sources, and publishes them so that the evidence and the level of confidence can be traced. Natural and synthetic dyes are looked at in the same way.

Publication is gradual: pages go up one by one, each once its sources have been checked and the site owner has read it through.

The site is written in Japanese first. The English edition is partial: only the themes and entries that have been translated appear in it. Some English entry pages were published before the site owner had read their English text.

The site's declaration appears in Japanese only, on the Japanese about page.

How this site is made and checked

Each page is made in the following steps.

StepWhat is done
Gathering sources and extracting claims and evidenceAI (Claude, by Anthropic)
Opening the original sources and checking against themAn AI other than the one that did the extraction opens the original source and rereads it twice. A coordinating AI also draws a sample and compares it with the originals.
Writing the textAn AI drafts it, a different AI reads it against the original sources, and the coordinating AI revises it. After the revision, another AI checks it again.
Policy and the decision to publishDecided by the site owner.
Reading before publicationEach page is read by the site owner.
Dyeing and photographsPeople do the dyeing. The site owner takes the photographs and keeps the records.
Illustrations and diagramsDrawn by an AI (Codex, by OpenAI); chosen by the site owner.
Translation into EnglishAI
DeclarationThe site owner's original Japanese text, unchanged

Each claim's evidence shows a verification status. “Checked against the source by AI” and “checked against the source by the site owner” are shown separately; only evidence whose original source the site owner has personally opened and checked, with a record kept for each item, counts as the latter. The site owner has looked through the original sources of the evidence and, for frequently read articles, has read those sources through. At present, 0 items have such an individual record (out of 3,951 items of evidence in total).

Each claim carries one of these labels: established, supported, preliminary, contested, contextual, observation, unverified. The label shows how strong the evidence is and how far the claim reaches.
