Date of Study: November 5, 2013
We have performed FT-IR microspectroscopic analysis on both sides of the Gospel of Jesus's Wife (GJW) and the Gospel of John (John) papyrus fragments. Professor Karen L. King of Harvard University provided the papyrus fragments on Tuesday, November 5, 2013.
The fragment is predominantly composed of oxidized cellulosic material, which is consistent with old papyrus.
The fragment is largely homogenous in chemical composition. We found one anomalous feature that we were unable to identify. We did not observe any major spectral differences between “bare” papyrus and papyrus coated with ink. We did not observe any major spectral differences between the recto and verso sides of the papyrus fragment.
The degree of oxidation is similar to that of the John fragment; however, the GJW fragment appears to be slightly less oxidized overall than the John fragment. Oxidation of the fragments is dependent on both their storage conditions and their ages, among other factors.
The fragment is predominantly composed of oxidized cellulosic material, which is consistent with old papyrus. Our analysis indicates that the extent of oxidation is slightly greater than the GJW fragment.
Like the GJW fragment, the John fragment is mostly homogeneous in chemical composition with no significant differences either between bare papyrus and papyrus covered in ink) or between the recto and verso sides.
The John fragment shares a majority of characteristic spectral features with the GJW fragments.
