Why do some metals ring when struck while others don’t?
In: Physics
Crystal thingies ring – not crystal (plastic) doesn’t.
Think stack of attached lego (organized, crystalline) vs. poured out (random, viscous) mound of lego.
Depending on the molecular structure and conditions of cooling to a solid state, crystalline structures may or may not have been formed.
Typically, quick cooling / super saturation leads to large, ringy crystalline structures, your mileage may vary, but I’ll use that as my jumping off point…
Crystalline things that have broken bits also don’t ring as well.
