Are mineral wool and rock wool ceramics?!

To quote a famous politician: "It depends on what the meaning of the word 'is' is."

Mineral and rock wools contain some proportion of crystalline and amorphous metal oxides and, technically, contain ceramics. They are like the cotton candy version of ceramics -- full of air -- which gives them their great insulation properties. But these wools also typically contain binders and oils, depending on the application. So this muddies the waters of definition. From a strictly purist view, you can't call them ceramics, because they are composite materials.

But I'd be comfortable saying that they contain ceramics and that the major component of most mineral wools is ceramic material.
