Everything will do that.
Not quite. A shiny steel ball bearing heated in a furnace along with a rusty dull ball bearing will barely glow a bit red while the rusty one will be a bright orange.
Not quite.
Yes, quite. Any material heated to the same temperature will look the same in FLIR. You're literally seeing the temperature, so the material is irrelevant.

That's because it will take the shiny steel ball's surface longer to reach a higher temperature. It's like the difference between holding a match to a 1 kg steel ball and 1 kg of steel wool.
No, the "insulation" effect of shininess works in both directions. I first found this out by trying to find out how hot I could make a paperclip with the alcohol lamp in my chemistry set as a kid. You're just guessing.
So you claim that a shiny steel ball heated to 1000°C will have a different infrared signature than a dull steel ball heated to 1000°C?
