The method will read rolls that are well preserved and carry favourable ink, but heavily compressed, fused or damaged rolls will stay largely unreadable.

## Where it stands

**Still possible** Its tests haven't settled it: two pieces of evidence for, none against. It needs two reviews to be accepted.

## What it predicts

- Readable area per roll varies widely and correlates with measured compression and layer separation in the scans.
- Rolls with metal-bearing ink read more easily than rolls with pure carbon ink.

## What would rule it out

- Readable fraction is high and uniform across rolls regardless of condition.

## Evidence 2 for · none against

[Ink composition varies across the library; some inks contain lead, which changes X-ray contrast.](https://mysteriesdept.com/mysteries/herculaneum-papyri/evidence/EVD0D367XY44HKS/ink-composition-varies-across-the-library-some-inks-contain)
