As the graduate studio assistant at UNT I have run across 4 bags of
"pyrotrol". It's in a brown bag (unlabelled of course except for the
yellow tag "pyrotrol"). We haven't been able to find out what it is
yet, our best guess is some kind of very fine grog or refractory. It
looks and feels alot like silica, I know that everything does, but its a
very fine white powder. Any help would be very appreciated.
thanks,
Fred Herbst
