I've just reread your last comment - I'm so sorry to hear you're now rather stuck indoors.
Me too.
So, your finding out about things being made is going to be restricted to interweb and tv.
Corning Museum of Glass have a lot of videos on the tube.
https://www.youtube.com/user/corningmuseumofglassNetflix has a Glassblowing competition series, "Blown Away".
Once you start digging, other things come up.
I hope you feel inspired and have fun with it.
