We are surrounded by glass - windows, light bulbs, water glasses. But glass is more than a permanent fixture in our daily life. At a sculpture exhibition called One Earth One Bird One Human, we are exposed to the magical world of glass. It has become a popular material for art creation in recent decades, and many art schools have introduced the study of glass sculpture. One Earth One Bird One Human showcases works by Colin Heaney, Noel Hart and Erika Mayer - three distinguished artists based in Byron Bay in New South Wales, Australia. Once you step into Gaffer Studio Glass, Hong Kong's first gallery dedicated to glass arts, you may be overwhelmed by the many colours and the extraordinary beauty of this seemingly ordinary material. Hart says that making glass sculptures is very technical and requires more than one person to finish the work. The chemical reactions of different types and colours of glass produce colours and effects that are always unpredictable. The three artists have different approaches to their creations. Hart, who initially began as a painter, is responsible for the One Bird part. He says that nature has always been his inspiration. His works feature bright and distinctive colours that can be seen among the 350 species of parrots. And the flat surface shows his origin as a painter. 'Parrots are animals that humans can relate to. They are the ambassa-dors for nature,' he says. 'In my abstract painting I always try to find the spiritual connection with nature, which is always my subject matter.' Heaney's creations head in a different direction. Most of them are in the shape of a vase and consist of the combination of dramatic colours. The rough texture of the surface is a result of different chemical reactions. But, unlike Hart, Heaney says he doesn't think too much when he does his artwork. 'People always put words to explain what other people do, but to me, people's response to art is important,' says Heaney, who would rather devote his energy to the ideas for visuals than expressing a message through his work. 'I experiment and make things that I enjoy making, and things that I think are beautiful.' Mayer's works are very different from those of Heaney and Hart. While the two gentlemen's creations are free-blown glass, hers are cast in crystal sandstone. You simply can't take your eyes away from the crystal-clear sculptures, which praises the beauty of human forms. 'I'm attracted by the transparency of glass, and I love the human-ness,' she explains. 'But I don't actually think too much about [my work]. Creativity comes when I'm not thinking; my mind is in stillness. I don't try to think of the meaning.' Glass sculpture is a relatively new form of visual art in Hong Kong, but the artists find that local people have a positive response to their creations. 'Not everyone is familiar with glass sculpture, so when they see it they are excited by the possibility of turning functional objects into some non-practical aesthetic objects,' says Hart. One Earth One Bird One Human is on until April 16 at Gaffer Studio Glass, Unit 5A, 15/F, The Centrium, 60 Wyndham Street, Central. Tel: 2521 1770.
