"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"

In this quote, artist Andy Goldsworthy is going over the unforeseeable nature of firing stones in a kiln. He describes that even when fired together, each stone will have its own special reaction. Goldsworthy's goal is to discover a balance between stones that have not been fired enough and those that are on the brink of being over-fired. This balance is important in creating an effective art piece, as excessive or too little firing can considerably impact the result. Goldsworthy's words highlight the fragile and elaborate process of working with natural materials and the importance of discovering harmony in their transformation.
