Core-formed and cast glass ships were first produced in Egypt and Mesopotamia as early as the fifteenth century B. C., but only began to be brought in and, to a lesser scope, made on the Italian peninsula in the mid-first millennium C. C. By the time of the Roman Republic (509-27 B. C. ), such vessels, applied as tableware or while containers for expensive oils, perfumes, and medicines, were common in Etruria (modern Tuscany) and Magna Graecia (areas of southern Italia including modern Campania, Apulia, Calabria, and Sicily). However , there is very little evidence in support of similar glass objects in central Italian and Both roman contexts until the mid-first 100 years B. C. The reasons in this are unclear, but it shows that the Roman glass sector sprang from almost nothing and developed to full maturity over a couple of generations through the first half of the first 100 years A. D. Doubtless Rome's emergence as the predominant political, military, and financial power in the Mediterranean universe was a major factor in attracting skilled craftsmen to set up workshops in the city, but essential was the fact that the facilities of the Roman industry roughly coincided with the invention of glassblowing. This invention modernised ancient glass production, placing it on a par when using the other major industries, just like that of pottery and metalwares (as 20. 49. 2-12). Likewise, glassblowing allowed craftsmen to make a much greater variety of figures than before. Combined with the inherent good looks of glass-it is non porous, translucent (if not transparent), and odorless-this adaptability stimulated people to change their likes and habits, so that, for example , glass drinking cups swiftly supplanted pottery equivalents. Actually the production of certain types of native Italian clay-based cups, bowls, and beakers declined through the Augustan period, and by the mid-first hundred years A. D. had stopped altogether. However , although broken glass came to dominate Roman glass production, it would not altogether supplant cast tumbler. Especially in the first half of the earliest century A. D., much Roman glass was made by simply casting, and the forms and decoration of early Both roman cast vessels demonstrate a very good Hellenistic influence. The Both roman glass industry owed the to eastern Mediterranean glassmakers, who first developed the skill sets and techniques that produced glass so popular that it are available on every archaeological site, not merely throughout the Roman empire yet also in lands much beyond its frontiers.
