Henry Sandon, who has died of a stroke aged 95, was regarded as the world’s leading authority on Royal Worcester porcelain, known to millions of television viewers for almost 40 years as one of the experts featured on Antiques Roadshow.
Sandon joined the show as a ceramics specialist – or “potaholic”, as he called himself – in 1980 for its second run, a year after the series started on BBC One.
