Liquid glass is poured over a bath of liquid tin where it floats on top, gradually cooling until it can be lifted off, annealed to prevent cracking, cut and packaged.
Also, this all has to be done without oxygen, because tin dioxide will stick to glass
Neat, I never even thought about why window panes were a thing. I like to make a game almost of not taking things for granted but that’s impossible to do completely, and it’s fun when some knowledge and insight comes along about an aspect of how things work that was invisible to me
Surprisingly some companies still make Drawn Glass, mostly sold for restoring historical buildings. Personally I like the slightly curved look it has.
I love seeing examples of the old ways still being produced. I always thought old glass panes weren’t totally flat because of the way things like glass and vinyl warp, and now I’m wondering if it was actually just that way since production. I’m not sure how long it takes glass to warp like that or how it would look different from drawn glass
Glass doesn’t flow, that’s a myth from the fact that when people installed drawn glass they favoured putting the thicker side down so that it was more stable.
