| Beschreibung: | Within the Restoration-Conservation Centre for Cultural Heritage of Iasi two early medieval manuscripts on parchment (Tetra Evangel and The Greek Evangel) were investigated. The restoring of these manuscripts gave the opportunity of a thorough research on the writing materials, pigments used in the ornamentation and the base material. The study of the base material, carried out by IR spectrophotometry (Transmission and ATR), lead to the identification of a natural polypeptide (parchment) (specific bands at 1630 cm-1- amide I and at 1530 cm-1-amide II), and also of calcium carbonate (chalk), used as surface covering material. Concerning the writing materials we identified ferro- gallic ink (The Greek Evangel), a mixture of ferro-gallic and carbon ink (Tetra Evangel – the first part), carbon ink (Tetra Evangel – the second part) and a cinnabar red ink (Tetra Evangel. The decoration of both manuscripts (frontispieces, lateral bands, frames, miniatures) are of a large chromatic varieties. The pigments were identified by optical microscopy, micro chemical tests and XRF. The pigments determined are: gold (Au), iron oxides (Fe), cinnabar, malachite, transparent copper green, madder lake, lead carbonate (Pb).The phosphorus (S) identified may come from a protein (yolk), used as glue or protection layer. |
