Appearances across the corpus
0.3 mm thick (12 thousandths of an inch), available in 1.5 × 1.8 m sheets. Fusion-drawn alkaline-earth boroaluminosilicate. Melting furnace nozzle and tube made of platinum (~$10M of platinum per furnace).
[Tom holds up a sheet of ultra-thin Corning glass.] If you go to the Corning website, you'll find that they will make glass for you that is 0.3 millimeters — twelve thousandths of an inch — thick, and you can buy it from them in sizes of one-and-a-half meters by 1.8 meters. So if you want to have a big TV screen, but it's only twelve thousandths thick. Be careful how you hold this — because it's brittle, believe me, it's brittle.
100–200 micron alkali-free borosilicate glass sheet, ~2014 release. Tom's inference: must be a laminated three-layer structure (like Corning Ware) with mismatched-CTE middle layer keeping surfaces in compression. Architectural backsplash application.
