“…By the mid-first century, Roman glassware was typically produced by the controlled blowing of melted glass through a pipe that was then formed into the required shape or, alternatively, mould-blown into a ceramic mould that was then manipulated [3,9,10]. Sometimes, these moulds contained manufacturers' brands, decorative motifs, texts or active scenes articulated in relief, including depictions of gladiatorial combat and charioteer games dating from c. 50-80 CE described by Pliny the Elder [2] (37.63-64), such as an exquisite example from Colchester, now in the British Museum collections, depicting gladiatorial scenes [11]. Blowing had a transformative impact on glassmaking, prompting the large-scale manufacture of an easily produced and diverse range of glassware vessels that were more accessible, affordable and, consequently, attractive to Roman consumers from across the full spectrum of society.…”
