The work of a 29-year-old pottery designer is held in such high regard by her employers that they have insured her for £1.5m.
Emma Bossons' work is responsible for 40% of the company's sales
Emma Bossons' career began on a £40-a-week government training scheme at Wedgwood in Stoke-on-Trent.
She then moved to the Moorcroft factory in Burslem as a pottery painter and was quickly promoted to designer.
Bosses at Moorcroft said Ms Bossons is responsible for 40% of the firm's £6m annual sales.
Chairman Hugh Edwards described Ms Bossons, the firm's youngest designer, as a "phenomenon" who had helped the company grow in a difficult economic environment.
He said: "It's not a case of saying that our other designers are no good because they are extremely good, but Emma is unbelievable."
