A striking similarity to the structure of mother-of-pearl (nacre) is displayed by the crystal architecture of highly oriented laminated CaCO3 coatings (see scanning electron microscope image ), which were prepared by a multistep procedure. A novel retardance imaging system (LC-PolScope) was employed to characterize the crystal texture of the polycrystalline thin films.
