I had a very long response typed up, but just deleted it because I cannot think of how to say my honest feelings without coming off aggressive or offensive. So I'll retreat from this discussion, and just say we have two points of view on this.
My point of view on "handling" museum work causes no potential danger to priceless works of art when you apply it to the millions of people through museums every year.
I'm sorry, and not to be contentious, but am I the only one that's a little horrified by the blasé attitude being given towards inappropriately handling what are, in all honesty, priceless and irreplaceable works of art?
If everyone with an "uncontrollable urge" (which is absolutely controllable) were to touch these vases / bowls / paintings / whatever... They'd either have to be locked behind plexiglass or they'd be destroyed by now.
It's the same kind of carelessness that leads people to take flash photography of delicate manuscripts like those on display in the British Library, despite many of postings not to.
No matter if you are in complete reverent awe of a piece, or if you're a curious five year old child, these pieces belong to posterity and we all have a social obligation to preserve them.
In a gallery where handling is encouraged? Absolutely. Go for it. In The Louvre? Tie your hands behind your back if you have to.
