Ca. 100-200 AD. A beautiful blown flask with an ovoid-shaped body, funnel-shaped neck with ribbed horizontal decoration, and two vertical trailed handles. Good condition, beautiful iridescence. The accretions (also known as 'weathering crusts') that are visible on the vessel are a result of age – the item has spent hundreds of years in the ground – and chemical reactions with the soil in which it was buried. While glass-making had been practised for centuries, the Romans invented the glassblowing technique in the 1st century BC, which revolutionized this craft. Roman glassmakers reached incredible artistic heights with both free-blown vessels and mould blown forms and decorations.
