Where in the blazes can one get plate glass blanks. I am on a tight budget but I want to make something fairly large ~17-20" and therefore I can't really afford much other than plate (since my last post, I looked at BVC prices and still found them to be a tad stiff). I will first learn on a smaller mirror, say ~10", at a mirror making class taught by our local mirror making Guru, so I think that I should be able to work with a large slab of thin plate glass upon completion of this class. (I've already done a fair ammount of background reading on the subject)

"Though parted by a gulf more impassable than any sea, the telescope lets us traverse what otherwise had been barred and lands us at last above the shores we went forth to seek. Real the journey is, though incorporeal in kind. Since the seeing strange sights is the essence of all far wanderings, it is as truly tavel so the eye arrive as if the body kept it company."
