I know theres some special centrifuge technique that that one guy uses to make those huge 8m lenses for telescopes. I would have to look it up again to get all the details, but maybe he could make it lol.
Are you familiar with the zeroedge aquariums? With proper lighting they just look like a cube of water sitting there defying physics. I imagine they could make one with low iron glass but i think the acrylic is much easier to engineer and work with. Id love to hear from someone who actually has one to hear how well they work.
