Hi Cynthia,
Permatill is one of the trade name for stalite, an expanded slate product.
It's also sold as vole-bloc. Like perlite, it is inert and porous, but it
does not float. It's a nice neutral grey, and the particle size is fairly
uniform, pea sized or smaller.
I don't have easy access to pumice, but I would image in that permatill
would work in most of the same applications. I use in mixes and also as a
top dressing.

Nick, could you describe 'permatill' for us? I know the term but not the
actual composition.
