glass
(hexbear.net)
its kinda crazy...
how do you think flat glass is made. what if i told you they fucking pour molten glass onto molten tin at like 1000° so it floats & forms a perfectly flat layer & then slowly bring the temperature down until the glass has hardened enough to exit the tin bath.
that's crazy but what about pre-1960 before that method was industrialized?? oh, they would just literally blow that shit into a cylinder and cut it down the middle & reheat it until it became pliable before smoothing it out no big deal.
ooey gooey molten glass, why do you look so enticing yet frightening....
