The Cross Punty
The cross punty is very similar to the way in which you make the marvered punty though using a blade of some sort you cut a cross mark deep in to the glass as close to the end of the punty as possible. This type of punty is useful for glass that has a thin base and has a high risk of cracking at the knocking off process. Temperature is of the utmost importance here. to hot and you will practically weld the punty to the piece, making it extremely unlikely to see the piece off the iron without a crack in it. Too cold goes without saying; cross punties are meant to be a fragile connection between piece and punty. Too cold and the piece will never see the light of day.
