Oh yes... one more thing.

Considering the lengthy thread on annealing this week and the importance of testing for 
stress; one thing that is difficult (nearly impossible) to do with the ASM product is 
test it for stress... it's black and cross polarizers are a useless with an opaque 
material.

However, I remember Bill Marriott was able to flash polish both sides of a piece of BVC 
and I seem to recall him getting light to pass through it.... I may have imagined this; 
maybe he'll chime in....

In Australia it's difficult to find mirror blanks, most come from overseas and cost a small fortune. Through your links I came across ASM products page and I was wondering if anybody out there had made mirrors using their products and if they hold their shape due to temperature changes. I want to make a 24 inch mirror.
