GRATUZE, Bernard ; BARRANDON, Jean-Noël
Islamic Glass Weights and Stamps: Analysis Using Nuclear Techniques
Archaeometry 32/2
University of Oxford, 1990, p. 155-162
Bibliothèque nationale et universitaire de Strasbourg (Strasbourg)

[650, 1250]
• Study of the seventy Islamic glass weights and stamps (from Umayyad to Mamluk Period) from the collection of the Bibliothèque nationale et universitaire de Strasbourg.

• Analytical method:
– analysis with a cyclotron fast neutron beam:
- determined elements: Na, Mg, Al, Si, Cl, K, Ca, Ti, Mn, Fe, Co, Ni, Cu, Zn, As, Rb, Y, Zr, Sn, Sb, Ba, Ce, Pb.

• Results:
– four compositional groups:
- group 1A:
objects stamped between 90 and 102-103 AH;
- group 1B:
objects stamped from 102-103 to 167-168 AH;
- group 2:
objects stamped from 167-168 to 254-270 AH;
- group 3:
objects stamped between 258 and 520 AH.

– differance between groups 1A-1B and groups 2-3:
- increase in calcium concentration,
- decrease in aluminium concentraion,
– interpretation: change in the sand used as raw material.

– differance between groups 1A-1B and 2 and the group 3:
- increase in the concentration of magnesium, potassium and manganese,
– interpretation: change in the source of soda:
groups 1A-1B and 2 – natron glass,
group 3 – either plant ashes or salt obtained from the watar of the Nile.
