That is what I suspected. You want ceramitized glass, not vitrified ceramic. They are a world apart in quality and price. Zerodur can be bought from Schott Glass Works in Germany or USA. I would guess that you are looking at about $20,000 US for the blank. For about 1/15 the cost you can have a 57mm thick (thin) Pyrex blank which will give supperior performance in typical applications.
