Rust was all we could see on the day we first saw Ulysses by Sri Satish Gujral and rust was what we had to struggle with, for nearly a month!
In spite of all the struggle and initial confusion about whats beneath the rust, the whole process of treating Ulysses was educating and a wonderful experience. We learnt so much more about how artists think of metal. colours, material and their interaction.
We could not get any old coloured picture of the artifact to refer to. Things like gilding, paint etc were showing up on their own once we could take control of the dominating rust.
