Notes

Used in structural clay coatings, refractory formulations, whiteware ceramics, art pottery to
increase refractoriness, reduce shrinkage, and widen firing range.
This material is made by crushing & screening of selectively mined andalusite/pyrophyllite/sericite ores
with heavy media separation.
