# Practical ceramics

The space shuttle had thousands of tiles that were close to the ultimate insulators. Has anyone gotten to the point where they're not $1000s a pound yet? I was wondering if anyone has created a thermos bottle that you could put in a microwave for a reasonable price. Why can't they spin off something useful from all those$ they spent on the shuttle?

I can't see what's so useful about a thermos that can be put in a microwave. A good thermos shouldn't need to be put in a microwave, and if you want to heat up your coffee anyway, why carry it in a thermos ? Or maybe I'm just used to getting hot (albeit lousy) coffee from the vending machine.

I think I'm missing the point here...I don't see the relevance of the ceramic tiles.
