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

Art for me is a form of nourishment. I need the land. I need it.

Stones are checked every so often to see if any have split or at worst exploded. An explosion can leave debris in the elements so the firing has to be abandoned.

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.

Generally in New York, people just walk over you with no problem about that. Other countries, people want to resuscitate you, like, after a bit.

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.

I can't edit the materials I work with. My remit is to work with nature as a whole.
