The state or quality of having a bullate surface; the formation of bubbles or blister-like protuberances.
From 'bullate' plus the noun-forming suffix '-ion,' which creates abstract nouns from adjectives. Traces to Latin 'bulla.'
Words ending in '-ation' often describe processes or states—'bullation' is what happens when a surface gets those bubble-like bumps, turning a descriptive feature into a process you can discuss scientifically!
