Imagine being an explorer, cracking open a 10,000-year-old tomb, uncovering a priceless ancient artifact – and getting rickrolled. Our deep descendants might just get the pleasure, thanks to a Global Music Vault due to be built in Norway, featuring Microsoft’s Project Silica, a tough new data…
Alright, but the article is talking about long to infinite timescales. The discussion above was about church windows and that is not caused by glass flowing.
Long to infinite timescales for it to crystallise, that is to solidify. This is explicitly noted in the abstract of the paper the article is based on. I understood the “short timescales” on which it “relaxes towards the liquid state” to mean more than one human life time based on figure 4 (the image also shown in the article), but not so sure about the 10ky cited in the OP though.
Yeah that might indeed be an urban legend, could be manufacturing artefacts as claimed here. However I will note that the version of it I am familiar with isn’t about “bull’s eye marks, warps, and lines” as that article states, but specifically about old windows being thicker only at the bottom.
