Hand-made: Meet the stonemason giving rocks 'life'
It was the honey hues of Yellowblock sandstone at the University of Sydney that drew Paul Thurloe away from his academic studies and into a 25-year career as a stonemason.
That same sandstone is now in short supply, with an estimated five years until Sydney's stockpile is depleted.
This is something that concerns Paul, who leads a specialised group of stonemasons restoring thousands of stone buildings owned by the New South Wales Government.
In the third of a series looking at people who make things by hand in time-honoured ways, the BBC met Paul as he restored a badly-weathered monument at the Public Works stone yard in Sydney.
