My memory is *my* second-shortest thing, too. :^)

It shatters into a jillion tiny cubes if you try to cut it. It has a
deliberately built-in stress pattern, and surface under huge tension. This
guarantees that the broken patio door doesn't decapitate your child with
large sheets of falling sharp glass. Much auto glass (not subject to rock or
gravel impact like windshields) is also tempered. Windshields are "safety
glass," which is a laminate of plastic between two sheets of normal glass
(also a brute to cut).
These glasses are essentially made to size, before the final bonding,
bending or tempering.

Plain old window glass. Double-strength for tank exteriors or even thicker
for tanks 20G or larger. Single-strength is great for smaller covers and 10G
or 5G dividers.
If you are filthy rich, you can avoid the faint greenish cast of window
glass by getting "water white" glass from various sources. A brand that
comes to mind is "Starbrite" but bring your armored car to the glass shop to
buy it. :-)
