Todays round of #MinCup24 is an easy choice. #Copper is all nice and shiny, but #Perovskite occurs in CAIs in chondritic meteorites. CAIs represent the first materials to condensate from the solar nebula, which means that perovskite is among the oldest solid stuff in our Solar System! That's way cooler than newbie-ish copper! 😎
Vote Perovskite! ✅️
