Good to have another geologist on the list Mary, Welcome.
It's good to hear that there is plenty of kyanite in the U.S. I was
recently unable to find a regular and economic distributor of this mineral
in Australia and New Zealand. I formulated a smooth raku clay body which
required -100 mesh kyanite to produce good thermal shock resistance.
However I was forced to reformulate this at the commercial production stage
using other acicular low-expansion minerals, due to the non-availability of
the kyanite.
Kyanite is a wonderful industrial mineral and I would utilise it in a number
of applications if I could get it reliably. But glazing is not one of them
because there are better more-fusible minerals around, which are good
sources of alumina and silica.
