You can pick up a space shuttle thermal tile right out of the furnace

Watch as a tour guide pulls space shuttle tile material out of a 2200-degree furnace and picks it up immediately. Note that for best results, pick it up by the cool corner or edge rather than the white-hot center.

If you're interested in the material and engineering, here is a great PDF on their thermal protection systems.
