This glass chandelier -- which looks to me like a big ball of fur -- was made by glass artist Robert Kaindl. At the link, you can see some simply amazing glasswork.
One does not clean or dust such big chandeliers- one lets them gather dust over the centuries while having outrageaous parties below them and swing from them, draped in Zorro-costumes and Musketeer-costumes....
I think it looks great.
:-D
