A homogeneous assemblage of glass vessels was uncovered in the lower part of an installation (cesspit?) during excavations in the vicinity of Ramla. The assemblage included bowls and beakers, bottles, jugs, a jar, an oil lamp and a miniature spouted vessel, whose fabric, quality and workmanship are typical of the Umayyad period. The glass is mostly bluish green or greenish blue, without corrosion and weathering, and with very common, simple decoration. The importance of this glass group lies in its dating to the beginning of the Islamic Era, i.e., the first half of the eighth century CE or very shortly thereafter.
