Does anybody know what Pyrax HS is? We have some in the studio and
nobody knows what it is for sure. Our best guess is pyrophyllite. Thanks
for the help! -=Rick=-

Pyrax HS is indeed pyrophyllite. It is sold by R.T. Vanderbilt of
Norwalk CT. 203/853-1400 If you call them they should tell you
who sells it in your area.

Hi Rick,
Yes, pyrophyllite - a hydrous aluminum silicate from R.T. Vanderbilt.
Aids in the formation of mullite at comparitively low temperatures.
Typical analysis

Al2O3 - 13.8
Fe2O3 - 0.2
TiO2 - 0.1
Na2O - 0.4
