Among the declassified CIA Reading Room documents sits a March 1965 technical proposal from Corning Glass Works' Electronic Products Division in Raleigh, North Carolina. The stated objective:

"Investigation of Improved Screens for Rear Projection Viewers."

What makes it fascinating isn't the mission — the CIA had insatiable appetite for better ways to view microfilm and reconnaissance imagery — but the shopping list of exotic materials Corning proposed to evaluate. Under "Materials Approach to the Problem," the table of contents catalogs:

"1. Passive Screens — a. Photosensitive Glass. b. Heterogeneous Materials. c. Polarizing Materials. d. Opal Glasses. e. MULTIFORM Glasses. f. Fiber Optics. g. Porous Vycor. 2. Hybrid Screens"

Read that again. In 1965 — the year Gordon Moore first wrote down Moore's Law, when American living rooms were dominated by cathode-ray tubes — Corning was pitching the CIA on fiber-optic display faceplates as a serious candidate for image viewing.

The list is a hidden history of Corning's forgotten glass technologies:

• Photosensitive glass (marketed as Fotoform) was Corning's remarkable material that could be exposed to UV through a mask and then chemically etched into intricate patterns — essentially photolithography for bulk glass, invented by Stanley Donald Stookey in the 1940s.
• MULTIFORM was Corning's proprietary sintered-glass process: glass powder pressed into molds and heat-fused into complex shapes impossible to blow or cast. It was, in effect, 3D-printed glass fifty years before hobbyists heard the term.
• Porous Vycor — 96% silica glass with nanoscale interconnected pores — is still used today in chromatography and as a substrate for optical sensors, but its consumer visibility has vanished.
• Fiber optic faceplates for displays did become real. They're inside every image-intensifier tube in night-vision goggles, and they were used to flatten the curved faces of early CRTs for reconnaissance readers — very likely a direct descendant of proposals like this one.

The proposal predates commercially available LCDs by roughly a decade and plasma displays by longer. Yet Corning, sitting on a catalog of glass materials most people have never heard of, was already sketching the material science of high-resolution flat displays for a customer who needed to see satellite film clearly enough to count vehicles.

Modern readers know Corning best for Gorilla Glass on their phones — a material also born from Stookey's mid-century experiments. What's forgotten is that the same lab produced photo-etchable glass, sintered glass shapes, and nano-porous silica, and that a Cold War intelligence agency was funding exploration of how to combine them into what we would now recognize as display technology.
