That’s a myth:

Maybe, but I prefer the liquid version — because it raises eyebrows.
I’ve never considered glass a liquid. Unless it is introduced to high heat.
Take a 60 year old piece of plate glass and measure it top and bottom and you will find that it has settled over the years with the bottom being thicker.
Thank you, that was very interesting. I often use glass in my kiln, and I’m always interested in learning more about it!
