In glassblowing the gaffer is the person in charge. The gaffer is the one who has a vision and plays that vision out in glass. The gaffer does the work needed to be done to create a glass vessel and directs the assistants who are helping to achieve the final form. On a given glassblowing shift two or more people will work together trading off between gaffing the pieces they have designed and acting as an assistant. Glassblowing is about teamwork. Gaffers and assistants must work together to be successful and to create great works of art.
