Antiques Roadshow visits the Ulster Folk Museum near Belfast, where treasures include stained glass, teacups from a luxury ocean liner and an unusual piece of medical history. Will Farmer is dazzled by a set of stained-glass windows decorated with mermaids, while Judith Miller admires a striking piece of costume jewellery found in an antiques shop in Australia. Adam Schoon hears the story of an ornately decorated mandolin found concealed in an old cupboard, and John Foster reveals the surprising value of a rare medical artefact — a Heatley penicillin vessel, designed to produce the life-saving medicine. The team are also intrigued by a silver milk jug from Kashmir and a huge bell from a Japanese temple, while Fiona meets the local blacksmith and marvels at a pair of goggles made for a chicken.
