2.2. Samples
33 glass samples were measured via LA-MC-ICP-MS. These samples
are Greco–Roman natron glasses, plant ash glasses and home-made
glasses [22]. From PN-MC-ICP-MS measurements, it was known that
the δ11B values ranged from −10 to +40‰ and the B concentrations
ranged from10 to 1000 μg·g−1. The sample descriptions and their B isotopic
composition as obtained via PN-MC-ICP-MS are provided in
Table 3.
