I've found several references that indicate Corning Glass Works developed the centrifugal casting process. Both the University of Arizona and Schott are noted for using the process for telescope mirrors.

“The centrifugal casting process (developed during the 1950s at Corning Glass) is used to make television tubes. A gob of hot glass is dropped into a funnel-shaped mold, which spins around, causing the molten glass to climb up the inside walls of the mold. A pressed glass faceplate is later sealed onto the open end of the glass funnel. Centrifugal casting on a much larger scale is used to make telescope mirrors (at the University of Arizona and at Schott Glass). In this case, tons of hot glass on a giant, heated mold is spun around so that the molten glass is forced to move toward the outer edges of the mold.”

This website describes the University of Arizona's history:
This is Schott's version (1988-1993): http://www.us.schott.com/advanced_optics/english/projects/e
This is not an exhaustive search! I am sending a selected list of references on centrifugal casting.
It includes references to the invention of centrifugal/spin casting and its development by Corning Glass Works for television tubes in the 1950s, as well as spin-casting mirror blanks.
You may wish to contact one of the following organizations as well. (Our museum library focuses more on the art and history of glass, with some technical information).
1)The Scholes Library at Alfred University, New York State College of Ceramics. They have a substantial collection of technical information about glass. Pat Lacourse answers technical reference questions (email:firstname.lastname@example.org). Their reference desk number is: 607-871-2951.
