The quality or state of being decorated with bosses or small rounded projections; the act or process of adding such decorative or structural elements.
From 'bosselate' (to decorate with bosses) plus the suffix '-ation' (forming abstract nouns of action or state), following standard English word formation patterns.
In art history, bosselation techniques show up across cultures—from Byzantine metalwork to Native American pottery—because humans seem instinctively drawn to adding three-dimensional texture to flat or smooth surfaces.
