Regarding that list of archived posts, I'd like to make one correction. I
believe that in one of them, I described Flourite as a fired calcined clay -
indicating my belief (at least at the time) that it was "fired" in a kiln as
part of the processing process. I'm not so sure anymore if this is the case.

Dr. Morin, could you please comment on this? You stated at one point I
believe that Flourite was a naturally mined material. Is it subjected to
high heat (fired) during processing (to increase internal pore space I would
assume) or is it just cleaned, crushed and bagged?
