Abandoning the project was incredibly stressful after having gone through the process of building the room, installing the kiln, collecting the stones, sitting with the kiln day and night as it came to temperature, experiencing the failures.
As with all my work, whether it's a leaf on a rock or ice on a rock, I'm trying to get beneath the surface appearance of things. Working the surface of a stone is an attempt to understand the internal energy of the stone.
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.
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 soon realised that what had happened on a small scale cannot necessarily be repeated on a larger scale. The stones were so big that the amount of heat required was prohibitively expensive and wasteful.
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.
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.
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.
Occasionally I have come across a last patch of snow on top of a mountain in late May or June. There's something very powerful about finding snow in summer.
