On the day we were there, we drank it all in and then traveled the 20 miles south on Interstate 91 to the main factory in Windsor. We perused the spacious shop and then headed for the glassblowing area. Being a weekday afternoon, we were alone but for a woman who had wandered in on the other side with a shopping bag over her arm. I couldn't help looking her way to see if she was as rapt as we were, and by all appearances, she was. It was pure performance art. The two glassblowers, a dexterous gaffer and his young assistant, were spinning a gigantic bowl out of what looked like rubber cement.
