An Antiques Roadshow expert left a guest almost speechless after discovering she'd been using a highly collectible jug as a simple watering can for her plants.

The beloved BBC programme visited Hopetoun House in Queensferry, near Edinburgh, where Roadshow expert Steven Moore encountered a visitor clutching a green jug that sparked memories of a beloved 1960s children's series.

"Were you by any chance a fan of The Clangers?", he enquired.

She replied: "No I wasn't a fan", prompting him to ask: "So was this the reason you bought this very ugly jug?"

"No, I bought it because I needed something to water my plants."

The guest revealed she'd snapped up the piece for a mere £2.50, adding that it "certainly lives up to its purpose".

"Right so this was last used for watering plants when?" he probed as she admitted it was just a "couple of days ago".

Moore then warned the guest: "Well, we might want to stop you doing that.

"It's made by one of the Ewenny Pottery's in Wales, very conveniently dated to 1902 and even more conveniently, we have a Welsh member on our team and she tells me that this literally means 'The Wild Pig'."

He tried to pronounce the inscription 'Y Mochyn Gwyllt' but quickly chuckled: "I apologise if I've said that wrong!"

Moore went on: "But I think it is a wild pig, not a Clanger, although there's some suggestion it could be a hedgehog but I'm not even going to go down that route.

"But Ewenny Pottery is very collectible so your £2.50 flower jug to a Welsh pottery collector, in the right sale, would be estimated at £800 to £1,200."

Upon hearing the staggering valuation, the guest took a sharp intake of breath before simply responding: "OK."

The specialist added: "So if I give it back to you, will you promise not to water any plants with it? And go buy a nice £2.50 plastic jug."

Grinning, she replied: "I promise. I will do that."
