[QUOTE="caojyn, post: 3037842, member: 5425"] [URL]https://io9.gizmodo.com/the-glass-is-a-liquid-myth-has-finally-been-destroyed-496190894[/URL] By studying a glob of 20 million-year-old amber, scientists have proven once and for all that glass does not flow. Some people claim that stained glass windows in old churches are thicker at the bottom than at the top because glass flows slowly like a liquid. We’ve known this isn’t true for quite some time now; these windows are thicker at the bottom owing to the production process. Back during medieval times, a lump of molten glass was rolled, expanded, and flattened before being spun into a disc and cut into panes. These sheets were thicker around the edges and installed such that the heavier side was at the bottom. [/QUOTE]
