In that pile of glass there are dust bunnies worthy of mounting on the wall of a lodge. There are gum wrappers, dead bugs, crumpled paper, and other miscellaneous blown-in leavings. And let's not forget the the crusty, dirty, smugged glass that is all in razor-sharp, shard form. This is a curatorial and conservation nightmare. If the whole thing were to be disassembled and cleaned, it would never be put back together the same way. On the other hand, if it is left as is... let's just say that you can't see the art through all the crud. Of course, that leads me to another question? Is the crud part of the sculpture? I am going to say 'no' since it started out all shiny and there have been minor attempts to spot clean over the years.
I am not going to say that artists should not make pieces that are impossible to maintain (I am not going to follow that rule) but I think that there should be some nod to the future conservation of any piece if it is supposed to be a permanent sculpture and not a temporary installation. Although it would be kinda funny to make a sculpture out of grapes, tissue paper, and puppies, just to see a museum deal with the mess. Take that future restorationists!! Muahahaha!!
