Simple, functional, and green as can be. These durable and refined every day drinking glasses are made from recycled bottles and jars that are gathered in Swaziland. The glass is melted in furnaces that are powered by recycled engine oil, then mouth-blown by local glass artisans and transformed into stunning new products. Ngwenya glass has a refined quality unlike any other recycled glass. This is in part because the Ngwenya glass blowers are trained by the company’s original glass artisans, masters who studied the ancient art at influential design firms in Sweden during the 1970’s.
