In pictures: Stoke-on-Trent's pottery history documented in exhibition
The last remaining bottle ovens in Stoke-on-Trent, the historic home of the pottery industry, have been documented for a new exhibition.
Phil Crow said photographing the 47 bottle-shaped structures was originally a way to unwind after visiting his mother in hospital.
The kilns operated until the mid-20th century and remain part of the industrial landscape.
"I hope the 47 remain 47 and that number does not dwindle," Mr Crow said.
His photographs will be exhibited at three sites over the next few months along with ones from Keele University's archive.
The idea for the showcase began when Mr Crow, who moved to Lincoln from Staffordshire, visited his mother in hospital towards the end of the Covid-19 pandemic.
"I would come down, see mum and then go for a walk to sort of decompress," he said.
"I started walking down by the towpath and just started photographing the kilns. It grew out of that."
The structures emerged in the 17th Century and Stoke-on-Trent Museums said at the height of pottery manufacture there were as many as 2,000 of them in the city.
But the Clean Air Act of 1956, along with the introduction of new gas and electric-fired kilns, put a stop to their use, the Potteries Bottle Oven Owners Club said.
"It's great some are left as they are important industrial heritage," Mr Crow said.
His exhibition began at Keele University and will run into May, before it moves to the Gladstone Pottery Museum and then Middleport Pottery.
