3/4 Plate Glass For Blanks?

I just recently purchased three pieces of 3/4 inch plate glass that are each 24 inches by 24 inches.
I am going to have them liquid cut into mirror blanks. My question is this, with 3/4 inch plate and a 9 point cell how large of a mirror can I get.
Understand that I will be cutting a variety of sizes from 6inch on up. I would like to eventually have a 12 inch F5, but thought that I might start with an 8 or 10 inch first to work out any bugs in my grinding process(Pendulum then tile tool). the 8 or 10 inch will keep my kids happy/occupied while I am looking through mine.

Thank you for your input Tony.

BTW I will also have the extra blanks available for any one interested. They have not been cut yet so if anyone is intrested I could cut one to there specs.
