More than 40 fragments of colorless glass from heavy baluster stem goblets were found in the archaeological excavation of the Casa dos Bicos in Lisbon, Portugal, in 1981 and 1982. This article focuses on 20 fragments from this collection, dated between the second half of the 1690s and 1755. The study was designed to identify the possible provenance of the goblets, based on the composition of the glass, as obtained by micro-energy-dispersive X-ray fluorescence, and the typology of the objects. The analyzed glass was determined to have a high content of lead oxide (25-39 weight percent), and a silica content of 49-59 weight percent. These heavy baluster stem goblets were typical of early English lead crystal production, and this archaeological set is, as far as we know, the largest ever found.
