ATM B.V.C. concerns

Greetings;
    Some members of our club are going to grind some mirrors this winter
and my thought was to use the BVC blanks offered through ASM in Canada.
I would like some feed back from people experienced with this product.
Questions I have relate to its ease of grinding, ability to determine
when polishing is complete(with pyrex you know when you can no longer
see the haze left on the glass), will it respond well to foucalt testing
, can you use a ceramic tile tool, will the coaters have a problem
aluminizing  and was the ASM prompt responding to orders. Also any other
peculiarities with the stuff. I thank you for your assistance .   Ron
