Hi All,
I came across a publicly available PowerPoint presentation about Kaolin, found at website http://www.smedg.org.au/may01.html (link off ppt file is http://www.smedg.org.au/skardonkaolin.ppt )
PowerPoint appears to be from 2001 but covers some good information about Kaolin, which I found useful and thought it may be of interest to others.
Regards
