John is a retired glass-maker who honed his technique and perfected the art of glass-making for decades. After retirement, he missed the pleasure of working with glass. As a means of keeping his hands occupied and his mind active, he decided to begin producing Prince Rupert's drops.

John has always been fascinated by the scientific qualities of glass, and the distinctive shape of Prince Rupert's drops gave him with the ideal chance to combine his passion for glass-making with his scientific curiosity.

He now spends his days producing each drop with precision and care in his modest workshop. Sharing his passion for glass and physics, he sells his drops on the Internet.
