Here are exposed the glass vessels and beads made in I-II BC in the Roman colonies situated if in the South of modern Ukraine. Here was the first glass production on the territory of Ukraine. The glass melting process was fairly primitive that time and it was quite difficult to achieve transparency. In this purpose it was necessary to blow glass as thin as possible. Ancient glassblowers were exceptionally well skilled and those vessels are the perfect demonstration of it. Their weight is less than 100 grams. It is hard to find nowadays the glassblower capable to perform such high-quality thin-walled glass using rather primitive tools.
