ver chloride. Environmental factors like
the exposure to high humidity or water
in addition to external chlorine prod-
ucts enhanced degradation processes of
ink and parchment.
Considering the eventful history of
the manuscript, the miniatures have
survived in surprisingly good condi-
tion. Nevertheless, the following changes could be observed. Most miniatures show abra-
sion, cracks in the paint layers and losses in different degrees (Fig. 23). Larger losses can
be found on folios 1 on both pages, folio 2, page 3, folio 3, page 6, folio 5, page 10, folio 11
on both pages, folio 12, page 24, folio 13, page 25, folio 14, page 27, folio 17, page 36, and
folio 18, page 36. Paint layers mixed with lead white, such as seen in the incarnate areas,
frequently show losses. On folios 11 to 14, the copper blue pigment azurite has caused
brown migration to the verso of the parchment (Fig. 24), see chapter on the miniatures.
The same phenomenon was caused by the use of the copper green pigment malachite on
folio 8. On many folios small patches of colour have been transferred from another page,
possibly due to water damage or high humidity: e. g. folio 4, page 8, folio 5, page 9, folio
12 on both pages, folio 13 on both pages, folio 14, page 28, folio 15 on both pages, folio 17,
page 35, folio 18 on both pages, folio 22, page 44, folio 23 on both pages, and folio 24, page
48 (Fig. 25). A large round lacuna in the painting layer can be found on folio 23, page 46,
and corresponding on folio 24, page 47 (Fig. 26). This loss might be caused by a wax drop
and the subsequent adhesion of the two pages. Yellow and white stains on the miniatures
could originate from the use of candles or oil lamps next to the codex. Stains with a wax-
like appearance show yellow fluorescence under UV-light, e. g. a stain in Joseph’s face on
