Is glass actually a liquid?
I have heard claims that the glass in old windows is actually thicker at the bottom than at the top due to it flowing. However this probably is the result of the poor manufacturing techniques at the time being unable to produce glass of constant thickness and then the glass being installed with the thickest end at the bottom. There is a lot more than the standard 3 phases of matter (gas, liquid, solid) and I have been told that the phase of glass is that of a glass. This isn’t particularly helpfull untill ur told that the glass phase is defined as a solid lacking long range order (ie untidy atomic positions) which when heated undergoes a pseudo phase transition from being solid to being runny. In it’s lack of long range order a glass shares a feature with a liquid. To be honest it’s probably just a pedantic issue of definition whether u call glass a liquid or not: I would feel stupid calling cold glass a liquid but what about hot glass (there isn’t a proper phase transition between bei
