Conservators at the Fitzwilliam Museum in Cambridge are working restore Qing vases that were shattered when a museum viisitor tripped and smashed into them. What will happen when they’re glued back together? They’ll go back on display. “These vases were given to us in the 1940s and have been in the same place for 50 years. Some 9 million people have walked past them and this is the first time they have been damaged. We have to look at the risk in perspective.”
