Thanks, Paul. I have read a couple of the papers that you have suggested for me. I found it easier to start with the work of Buchwald and Wivel I must say, but I will understand the maths with a little more application. It is clearly a matter of calibrating the various oxide ratios for lots of different ores, which is the sort of thing that I shall be doing at Warwick. They are very good at inclusions in modern steels at Warwick. I don’t know Maxime, but I shall obviously have to contact him and his co-workers some time, possibly when I understand a little more about it.

As part of my researches I intend to go to the conference at Falun in Sweden in June. Do you know of anybody else from the Society going?
