IPA: /ˈɡlɛərɪŋ/
KK: /ˈɡlɛrɪŋ/
The act of applying a mixture of egg whites and water to surfaces, often used in bookbinding to prepare for gilding.
The glairing of the book covers made them ready for the gold leaf application.
Glairing is derived from 'glair' (from Old French 'glaire', meaning egg white) and the suffix '-ing' (indicating the action or process). The word 'glairing' refers to the act of shining or reflecting light, akin to the glossy appearance of egg whites.
Think of the shiny, reflective quality of egg whites ('glair') to remember that 'glairing' means to shine or reflect light.
