Halfway through making many glass forms, one must transfer the shape onto another type of iron – a punty. This allows the glassblower to work on the other end of the piece.
Here a pad is being shaped on the end of a punty.
The two irons (the original blowing iron where the form has started, and the punty where the piece will be finished) must then be made absolutely parallel on the same axis.
The glass is then scored and broken off just next to the tip of the blowing iron.
Once a shade has been transferred to a punty, the other end of the piece can be shaped.
