Paper Material

  • Format Metric
  • Weight Single weight
  • Thickness (mm) 0.18

  • Material Techniques Developing-out paper
  • XRF

    This work was determined to be a gelatin silver print print via X-ray fluorescence (XRF) spectrometry.

    The following elements have been positively identified in the work, through XRF readings taken from its recto and verso (or from the mount, where the verso was not accessible):

    • Recto: P, S, Cl, Ca, Zn, Sr, Ag, Ba
    • Verso: Al, Si, S, Ca, Zn, Sr, Ba

    The graphs below show XRF spectra for three areas on the print: two of the recto—from areas of maximum and minimum image density (Dmax and Dmin)—and one of the verso or mount. The background spectrum represents the contribution of the XRF instrument itself. The first graph shows elements identified through the presence of their characteristic peaks in the lower energy range (0 to 8 keV). The second graph shows elements identified through the presence of their characteristic peaks in the higher energy range (8 to 40 keV).

    Areas examined: Recto (Dmax: black; Dmin: green), Verso or Mount (blue), Background (red)
    Elements identified: Al, Si, P, S, Cl, Ca, Ag, Ba
    Areas examined: Recto (Dmax: black; Dmin: green), Verso or Mount (blue), Background (red)
    Elements identified: Zn, Sr, Ag
