Mirror Glass

[A.S.I.G.N_Baz]

Can anyone tell me if Annealed float glass 19mm to 25mm thick and 16 to 20 inches across would be good enough for mirrors to grind at home?

I have never build one before but I would like to give it a crack.

I know it may be better to try a smaller mirror as a first go, but I already have a commercial 11" SCT and it doesnt make sense to me to make a smaller telescope.

Information overload is good, but please try to keep it simple as I am a bit slow....
