The relationship between the public and the artist is complex and difficult to explain. There is a fine line between using this critical energy creatively and pandering to it.
Winter makes a bridge between one year and another and, in this case, one century and the next.
I am not a performer but occasionally I deliberately work in a public context. Some sculptures need the movement of people around them to work.
Three or four stones in one firing will all react differently. I try to achieve a balance between those that haven't progressed enough and those about to go too far.
It takes between three and six hours to make each snowball, depending on snow quality. Wet snow is quick to work with but also quick to thaw, which can lead to a tense journey to the cold store.
Ideas must be put to the test. That's why we make things, otherwise they would be no more than ideas. There is often a huge difference between an idea and its realisation. I've had what I thought were great ideas that just didn't work.
I'm cautious about using fire. It can become theatrical. I am interested in the heat, not the flames.
I have worked with this red all over the world - in Japan, California, France, Britain, Australia - a vein running round the earth. It has taught me about the flow, energy and life that connects one place with another.
I have walked around the same streets so many times, and then seen a place that had been hidden to me. I now know the sites in a way that makes me think I could have made better use of the connections between place and snowball.
My art is an attempt to reach beyond the surface appearance. I want to see growth in wood, time in stone, nature in a city, and I do not mean its parks but a deeper understanding that a city is nature too-the ground upon which it is built, the stone with which it is made.
I did tests on small stones before collecting and committing myself to the larger ones.
Not being able to touch is sometimes as interesting as being able to touch.
Fire is the origin of stone.By working the stone with heat, I am returning it to its source.
Even in winter an isolated patch of snow has a special quality.
Confrontation is something that I accept as part of the project though not its purpose.
