- tifik 2y agoWould/does that actually work? Its been a while since I watched SED Destins video about it, so I dont remember if they experiment with that. But intuitively, heating the glass so non-uniformly that the tail would melt and the bulb remained solid enough to keep the internal stresses intact, wouldnt that steep temperature gradient within the crystaline structure cause the entire drop to break?
- maxbond 2y agoIn this video someone does it and it seems to work. https://youtube.com/shorts/ERDmKW65t38 https://youtube.com/shorts/ERDmKW65t38 But it's a very small drop and they don't melt it all the way to the bulb. I imagine that it could shatter in some circumstances. (Incidentally glass isn't a crystal, but that's just a nitpick.),
- prox 2y agoIs glass still considered a form of liquid? Think I remember reading something about that years ago.
- sparky_z 2y agoNo, that's a classic misconception. People claimed that windows "flowed" because really old ones were thicker at the bottom, but that was just how some old window glass was made.
- dasil003 2y agoYeah if you’re installing an uneven pane where would you orient the thick side?
- Hikikomori 2y agoThe bottom.
- gweinberg 2y agoI think the basis of the claim is that glass doesn't have the same kind of phase transition that a crystalline solid would. It just sort of gradually becomes more liquid-like as you heat it.
- s0rce 2y agoNo, its disordered (ie. not a crystal) but not a liquid, it won't flow like a viscous liquid.
- s0rce 2y agoMy comment was a bit over simplified, they do flow, but the time scale exceeds the entirety of human history [1]. [1] https://doi.org/10.1119/1.19026 https://doi.org/10.1119/1.19026
- maxbond 2y agoSimilar to the misconception that Earth's mantle is liquid. It isn't, but time is deep enough for solid rock to flow.
