Tiles burn up?

Not if they are facing the direction they are supposed to.
What would happen as it is hurtling through space twisting and turning in every direction?
I don't pretend to know, just bringing it up.

The backing would certainly blow disintigrate. One aspect of the tile substance I hadn't considered is pulverization. The ceramic portion might not burn, but it might be turned to dust by atmospheric terbulence.
