## The record.

From the registry, rebuilt from Peter's researched material cards. Label: purple-navy-series pure black (紫紺系の純黒). Boku-Undo's refined synthetic resin binder: water resistant once dry, will not bleed in wet mounting, no gelling in cold, does not spoil. Previously recorded as a Chinese "Mo Huang" ink; the maker is Boku-Undo.

THE ENGINE

## What V23 read on it.

The mean rung on each ladder for paintings made with it, against the mean across every V23 reading. This mixes the material with the months it was used in; read it as a description only.

Bead: the mean rung on this material across 76 V23 readings. Ring: the mean across all 259. The line between them, and the number at the end, is how far this material sits above (cyan) or below (ember) the archive.
