Abstract

The glass was produced by the same recipe all over the Roman Empire and its chemical composition varied in a narrow range. There is no consensus whether the base glass was produced in few centres and then distributed for further processing, or base glass was produced in many glass-making workshops keeping the recipe strictly. This paper is the first to report about chemical composition of glass objects unearthed from Roman time glass-making workshops in Pannonia, contributing to the above mentioned dispute. One of the 5 studied transparent glass objects found in a glass-making workshop in Brigetio (now Komárom– Szőny in Hungary) is potash glass, which was probably made in the early modern era and mixed accidentally to the Roman objects. The other 4 transparent and translucent glass objects are of typical Roman base glass in composition. The base fragment of a very high quality bowl does not contain deliberately added manganese, while all the other transparent fragments are decolourised by manganese. This high quality glass bowl was probably made in another workshop in the Roman Empire or in Pannonia as the style of the object indicates it as well. The opaque white and opaque yellow glasses were opacified by calcium-antimonate and leadantimonate respectively according to the common practice in the Roman Empire.
