Subject: [Clayart] History of Gerstley Borate

I looking for information of the history of Gerstley Borate,
especially
 when and how the mine was discovered and when the material was first
used
 as a pottery or glaze ingredient. There is lots of chit-chat on the
 problems of using it and rumors of its demise, but its background
seems to
 be sparse.
 Any leads would be appreciated.
