One of the beauties of art is that it reflects an artist's entire life. What I've learned over the past 30 years is really beginning to inform what I make. I hope that process continues until I die.

It's frightening and unnerving to watch a stone melt.

I love the winter. Well, I love all the seasons, but the winter is possibly one of the most intense.

People do not realise that many of my works are done in urban places. I was brought up on the edge of Leeds, five miles from the city centre-on one side were fields and on the other, the city.

The hardened mass of liquid stones had much stronger qualities than those which had simply torn. The skin remained a recognisable part of the molten stone.

For me looking, touching, material, place and form are all inseparable from the resulting work. It is difficult to say where one stops and another begins. Place is found by walking, direction determined by weather and season. I take the opportunity each day offers: if it is snowing, I work in snow, at leaf-fall it will be leaves; a blown over tree becomes a source of twigs and branches.

The main reason I went to digital was because I got time-lapse, video, and still images all in one camera. Having a minimal amount of gear is really important for someone who wants to walk around. That allowed me to have this flexibility to document things in different ways.
