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.

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.

I'm cautious about using fire. It can become theatrical. I am interested in the heat, not the flames.

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.

The stones tear like flesh, rather than breaking. Although what happens is violent, it is a violence that is in stone. A tear is more unnerving than a break.

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.
