The early 1st century process of blowing two bubbles of glass, joining them at their tips, then creating furnace-finished rims on both ends is one that countless glassblowers have used in the ensuing two thousand years. Particularly in western Europe during medieval times and the Renaissance, building compound objects by this method was widely practiced. The video commences with the completion of the vessel body. In Jerusalem, sometime about 40 B.C., it was discovered that molten glass could be inflated. To make this phenomenon useful and practical, manufacturing processes had to be invented. This occurred during a rapid expansion of the Roman Empire that eventually included the entire Mediterranean Basin and extended to the far eastern coast: present-day Israel. Through an extensive trade of goods and the widespread movement of people and know-how, glassblowing found its way to the Italian peninsula. It took root and developed quickly. Glassblowing spread to become—then, as now—the predominant method of making glass vessels. Learn more at https://romanglassblowing.cmog.org.
