But James, you went on to support the idea in what you said that
Flourite
and soil are not the same thing. Flourite is clay, pure clay.

Best regards
PLEASE ....
Fluorite is NOT clay. It may have been once but it isn't clay anymore.
A clay is a soft thin platy mineral. If it is hard it's been altered
and is
something else.
Fluorite looks like clay that has been altered either by fire or
mineralization.
Despite having more luck with it than other substrates ...
I must admit personally as a geologist I find the name it's self
objectionable.
fluorite is calcium fluoride a mineral.
