Want Some Bubbly?

Ever wonder how the Italian artisans at Barbini achieved such uniformity in bubble design? One theory is that the molten glass takes a quick nap on a bed of nails (like so many Swamis) prior to being layered and cooled. The ostrich-like pattern is commonly referred to as "controlled bubbles".  This exquisite example is quite large at 6.5" square and just over 3" in height.
