That’s so cool that this exists, but it’s not surprising crystallization releases heat. That’s an exothermic process.

Makes me think of amorphous metals.

Haven’t looked at those things though since a material science recruitment demo where we bounced a rubber ball off one. (Amorphous structure absorbs less kinetic energy than a crystalline one so you get way more bounce off an amorphous metal surface than a crystalline one, which looks real weird)
