What does glazing mean?
Glazing is the glass or similar transparent material used in windows, doors, and other openings, as well as the process of installing it. It also has a second established meaning: a smooth, glossy, often transparent coating applied to pottery, ceramics, food, tiles, or other materials. The architectural sense includes both the finished window or door covering and the work of fitting it. Architectural glazing is valued for admitting daylight while separating indoor spaces from the weather, and forms such as double glazing also provide insulation. The coating sense is especially associated with pottery, where firing creates a durable glass-like surface, and with confectionery, where a glossy layer improves appearance and texture. As a verb, glazing can mean either fitting an opening with glass or applying a glossy coating. The word is common in professional construction, conservation, crafts, and culinary contexts and is readily understood beyond those fields.
Glass or similar transparent material fitted to a window, door, or other opening; the act or process of installing it. Also, a smooth, glossy, often transparent coating applied to pottery, food, or another surface.
"Specialists replaced the cracked glazing in the historic windows."
The dominant architectural sense covers both the material and the installation process. The coating sense is common in ceramics and food preparation.
To furnish an opening with glass or another transparent material, or to apply a smooth, glossy, often transparent coating to a surface.
"The technicians are glazing the new conservatory roof."
The appropriate sense depends on what is being glazed: an opening receives glass, while pottery, food, or another object receives a coating.
The plural is uncommon but is used for individual glazed panels or separate pieces of fitted glass.
"Several original glazings were removed so that the frames could be repaired."
Before large panes of plate glass became practical, windows had to be glazed in many small pieces, turning decorative leadwork into an architectural necessity.

Where does glazing come from?
Glazing was formed in English from glaze using the verbal-noun suffix -ing. Glaze came through Middle English glasen from Old French glase, a word closely associated with glass. Glass itself has an Old English ancestor, glæs, and ultimately continues Proto-Germanic *glaz-, a word also reflected in related Germanic languages.

How glazing is actually used
In architecture, the term is common in both British and American English, although regional vocabulary differs for individual panes and their supports. In ceramics and food preparation, glazing usually denotes a decorative or protective coating rather than window glass.
Easily confused with glazing
