That application would certainly test the temperature extremes:
the deep cold of space and the unbelievable heat of atmosphere
re-entry on shuttle's return to earth!
Cold, yes perhaps, but less than you’d think. The shuttle body
itself is radiating internal heat (why they need those door open to
get rid of excess heat). Vacuum itself is neither hot nor cold.
space itself doesn’t have a temperature. The inner surface of the
tiles is extraordinarily well insulated, and will retain some of the
heat from the shuttle body quite well. And the tape side of the
tiles doesn’t get that warm during reentry. These tiles are amazing
things. pull one from the furnace at a bright glow, wait for the
outer surface to chill for a moment, and though the interior is still
glowing brightly, you can pick it up with your fingers. it’s THAT
good an insulator.
Do you think 3M might make samples or small quantities
available to jewelers? What is the name of the stuff?
Don’t know. A fellow I worked with, a former senior exec at Kodak,
had gotton some to play with. He had the pull to get samples.
Whether an ordinary jeweler could do it, I don’t know. But 3M is
courting jewelers these days, so who knows. A warning: As I recall,
this stuff was VERY expensive, and you couldn’t buy only small
