The format for this Netflix show is simple – take a group of glass- blowers and, each episode, give them a challenge and eliminate whoever performs worst. This format is particularly brutal because it doesn’t give the competitors a chance to redeem their mistakes – one false move and they’re out.
When working with glass, it’s easy for one false move to result in the utter destruction of the piece you’re working on. While this can happen at any time, a particularly risky time is getting the piece off the punty (a metal rod used to hold the glass as it’s worked) and into the annealer (an oven that very slowly cools down the glass to room temperature to ensure that it doesn’t crack).
It doesn’t matter how well your glass is worked, if your tap to break it off the punty is a little too hard, or you don’t hold it properly, all you’ve made is a pile of broken glass.
