The article describes the author's experience of a day-long class in glassblowing at a studio in London. It draws out a number of analytic themes in making sense of the pedagogy and the learning experience. The article also makes explicit comparison with the work of Erin O'Connor, who has also studied glassblowing at a studio in the United States. Conclusions are drawn simultaneously about the stability of the craft and pedagogy of glassblowing, and also about the craft of ethnography itself.
