It depends who you mean by "they". Glass was not widely available during the Anglo-Saxon period, except for the most wealthy who had drinking vessels of green glass. Small bottles, beakers and other items were made of green glass through the medieval period, but it was always very expensive and out of the reach of most people - much of it was imported from the Middle East, Italy and other parts of Europe.

Glass blowers are craftsman that create pieces of glass. Automation and the advent of plastics have greatly reduced the number of active glass blowers.

By shaping the glass, adding colors, attaching handles and bases and other key items, they create unique works of art that are used as vases, glasses, pitchers, and any other sort of container that can be formed with glass. Some still use metal molds that force the bubble into a specific shape, the way most early glass bottles and containers were created. Glass blowers were actually some of the first craftsman in North America. One of the first industries in Jamestown was a glass factory.
