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.
