Comparative form of glairy; more resembling glair or egg white in consistency or appearance.
From glairy plus the comparative suffix -er. Glairy is formed from glair plus -y (as in 'creamy'), and glairier is the natural comparative formation. Used in technical and historical descriptions of viscosity and appearance.
The fact that we can add -er to glairy to make glairier shows how flexible English is—we can describe something as 'increasingly egg-white-like' with a single word.
