Air Burial (Oslo), is part of a group of cylindrical glass sculptures developed by Horn since the 1990s. The glass is melted and poured into the cast, before it is left to set over a period of several months. This process gives the work its characteristic expression of a translucent exterior and a transparant, seemingly liquid interior.
The title of the work refers to a Tibetan funerary ritual of leaving the body of the deceased lying on a mountain top, exposed to the elements of nature. Slowly but surely, the sculpture will break down over time becoming one with its surroundings.
