Hey A.K.,
We haven't used pyrex, but I know that PECVD and low temperature LPCVD
oxide (LTO) both work fine on borofloat glass. I suspect pyrex will work
just as well. The only possible problem may be that the pyrex *might* not
be able to handle the temperature of LTO (about 450 C). You should have
some specififcations about the maximium temperature your glass can
withstand.
