Ngwenya Recycled-Glass Blowing

Ngwenya ('crocodile' in siSwati, the name of both the mountain and village where the factory is located)

The hand-blowing of glassware and figurines from 100% recycled glass -- primarily used soft-drink bottles collected across Eswatini -- at the Ngwenya Glass factory, near the Ngwenya border post beside Mount Ngwenya, a peak whose crocodile-like silhouette gives both the mountain and the glassworks their name, and which is separately notable as home to the oldest known mine in the world. The factory originated as a 1979 Swedish government aid project, initially named Swazi Glass Craft, which supplied glassblowing equipment and sent Swazi trainees to study at the internationally celebrated Kosta Boda glassworks in Sweden. Management transferred to the Swaziland Small Enterprise Development Corporation in 1981, but production halted entirely in 1985. The closure specifically distressed the Prettejohn family -- Richard, Alix, and Chas Prettejohn, South African collectors devoted to Ngwenya's glass animal figurines -- who, following a chance visit to investigate the factory's fate, made the decision to revive it in 1987, restoring production under the Ngwenya Glass name. Today, visitors can observe glassblowers working the glowing furnaces from an overhead balcony, transforming collected glass into tableware, animal figurines, vases, wine coolers, candle holders, decanters, perfume bottles, and paperweights, with designs frequently drawing on the animal themes of the surrounding wildlife-rich region alongside broader Swazi cultural motifs, including stylized warrior figures used as decorative glass stems. The enterprise operates a series of documented eco-friendly production practices throughout, and its products are exported worldwide, with an additional dedicated boutique at the V&A Waterfront, Cape Town, South Africa.
