You're always frustrated, you don't have the chance to do a song on the album, like the Beatles did with Ringo and George, or like Led Zeppelin, where everybody was given a chance to contribute. There never is a chance with the Stones. ↗
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. ↗
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. ↗
Having loved the Stones all the time I was growing up, I wasn't about to see them go and split up. It got very close to it in the 80s, when Mick thought that Keith hated him and vice versa. ↗
