Everyone wants a tough flexible coating but what about the opposite.
Does anyone have a list of brittle coatings?
The salt that dries on pumpkin seed shells might be a start in the right direction.

Are you thinking of someting like an abradable coating.?
That might not necessarily be brittle. A ceramic might be what I want, although high temp. is not an issue.

To do what? Don't ask for a material reccomendation without specifying the application or (if it's proprietary) a reasonably complete list of the desired material properties.
If you don't know where you're going, we can't tell you how to get there.
Yes, for example, a thin layer of plaster on a balloon.

If abradable certamics are not what you want are you looking for Are you looking for a coating that cracks and flakes off when deformed; to serve a function similar to impact indicator paints?
An electric tractor made out of plaster? Is that the application? I wonder who currently owns the rights to the Trabant brand name?
