   I'm pretty sure ceramic materials like ferrites can't be damaged by mild heating when enough 
heating to shatter them doesn't change the magnetic properties, after being epoxied back together 
the work like new.
I have never heard of ferrites or powered iron cores being altered without physically damaging them.
