The site excavated at Kefar Sava yielded 42 poorly preserved glass items, which originated in the Early Islamic period occupation and in the Ottoman-period cemetery. In addition, small chunks of raw glass, found together with minor remnants of blown vessels, might attest to glass production in the area during the Byzantine–Early Islamic periods. These finds complement Ayalon’s findings in his surveys, which pointed at evidence of glass production in the Kefar Sava area.
