An exhibition comparing genuine and fake Chinese porcelains has become the subject of controversy after some experts said that most of the purportedly fake items - previously smashed on a TV show - were in fact genuine.

Organizers of the Beijing exhibit dismissed the accusations, stating that a battery of experts had already carefully examined the items.

The exhibition was organized by the Capital Museum and by World Collection (Tianxia Shoucang), a Beijing TV program that evaluates ancient porcelains. The Capital Museum exhibit has more than 40 genuine ancient porcelains and more than 30 repaired fake ones, a museum spokesperson said on Monday.
