Hailing from the town of Odumase-Krobo, the epicentre of Ghana's traditional glass bead culture, Tetteh discovered glassblowing in 2012 after spending several months in France and the Netherlands learning the craft with other Ghanaian bead-makers.
He was alone in his desire to continue upon returning home, and set a goal to establish a proper hot shop in Odumase-Krobo.
Undeterred by lack of finance, he built furnaces from scrap-metal and clay using online tutorials. He fine-tuned his abilities watching YouTube videos of famous glass artists like America's Dale Chihuly.
