Janine Altman was born in Uruguay. Studied painting, jewellery, engraving and fused glass as a child. She studied Systems Engineering at Engineering University in Montevideo, Uruguay. Then she felt the need to go back to the art world, which is why in 2002 created her atelier to start an artistic journey of experimentation and discovery within this fantastic world of glass. Altman works with glass using several techniques, such as, Fusing Glass, Flameworking, Casting and Pate de Verre. Moreover, she developed a new technique which she named Openwork Glass. Briefly, it consists of units of glass joined by metal threads. Her artworks are usually inspired by the universe and nature, appeal to different forms and textures in a context in which different tones and nuances complement each other to produce unique pieces. We can notice in her works the presence of geometric and abstract forms, which come together in her own style, as eclectic as it is avant-garde.
