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…
my ancestors were glassblowers. Unfortunately they immigrated to Pennsylvania to mine coal and so no cool glass blowing skills were passed down to me.
