I think Kodak still sells glass plates (Timex 100) for scientific and industrial uses. Expensive but available by speical order. I would guess that plates are available in China, Russia, and Japan for the same reasons. But for 20XI24, they would be very expensive. Making plates at home, because of the toxic materials (at least in Arizona) you would need a permit for industrial use. The police will think you are making crank.
