One of Britain’s leading stone sculptors, Paul Vanstone talks about his fascination with stone and how he loves the openness and risk-taking involved in carving it, the feeling of vibrancy that it gives him in particular marble for its variety of colours and texture, how he honed his carving skills in Italy and India, the challenge that AI robots are beginning to pose for sculptors and the influences both classical and modern that one can see in his heads, torsos and reclining figures.
