• Chemical analyses of Islamic glass from Rāya - some characteristics:

– about 1000 samples of glass selected from more than 15 000 pieces excavated in Rāya analyzed since 2001 by means of a portable X-ray fluorescence spectrometer (PXRF);

– analyses: Al2O3, K2O, CaO, TiO2, MnO, F2O3, SrO.

• Classification of compositional types and their production dates and regions:

– N1-type:
- natron glass with low magnesium (Mg) and potassium (K) content, and high strontium (Sr) content;
- appears to have been produced in the Syro-Palestine region, probably at the Bet Eliʿezer primary glass workshop;
- from 8th century context;
- includes lustre-stained, pinched decoration, etc.

– N2-type:
- natron glass with low Mg-, K- and Sr-content;
- Egyptian primary glass workshop production;
- N2-a-type: 8th century;
- N2-b-type: 9th century;
- includes impressed, lustre-stained, scratched, mould-blown, black painted decoration, etc.

– PA-type:
- plant ash glass with high Mg-, K- and Sr-content;
- unknown production;
- from post 9th century context;
- includes cut, impressed, orange-lustre-stained, mould-blown decoration, etc.

• Question with regard to the change in the alkali source: from natron glass to plant-ash glass.
